Coldwater, MI: While Ford is gearing up to begin shipping 2021 Ford F150, the team at BDS Suspension took advantage of their early access to the all new F150 (through Ford's Auto Night Event) to swiftly work through the development, testing, manufacturing and ultimately release of new lift kit options. With that BDS Suspension is excited to announce first to market 4" and 6" lift kits for the 2021 Ford F150 designed to improve on-road handling and offroad capability. Available as standard (strut spacer) IFS systems or FOX 2.5 factory series coilover systems, BDS takes the new Ford F150 to the next level with clearance for 35-37" tires. These systems are based around the tried and true high clearance technology that has made BDS the go to for F150 trucks and are designed from the ground up to get the more out of your truck with the most ground clearance on the market.

At the heart of these new lift systems a pair of specially designed 1/4" thick laser cut high clearance crossmembers to maximize clearance and provide a solid mounting point for the OE lower control arms. These paired with the heavy duty front skid plate system create a rigid subframe while adding protection for vital steering and driveline components. In place of the factory steering knuckles a pair of newly designed ductile iron replacement steering knuckles are supplied to accomodate the new OE sway bar mounting location while maintaining proper steering geometry for ESC system compatibility. The front differential is repositioned via multipoint relocation brackets to keep CV angles in check. A billet aluminum front driveshaft spacer is supplied along with longer hardware to allow the reinstallation of the factory driveshafts. A pair of BDS-branded sway bar drop brackets used to correct the operating angle of the factory sway bar as well as created a strong brace between the rear crossmember and the frame. Rounding out the front of this kit are new lower control arm cam bolts to allow alignment and a weld-in frame reinforcement plate for extra strength.

In the rear of these lift systems, the factory block is replaced with either a 3" or 5" lift block and longer u-bolts to lift and level the stance depending on front lift height. Also included, BDS supplies brake line and ABS line brackets allow the use of factory brake lines. Specially tuned NX2 twin-tube gas or FOX 2.0 IFP performance series monotube gas shocks are supplied to round out the rear of these kits. All kits come finished in a durable textured black powdercoat and sent with all hardware packs to complete the install along with step-by-step installation instructions. All BDS kits include Factory Protection Plus for the ultimate extended warranty to include BDS's No Fine Print Warranty, ESC System compliance and a 5year-60,000mile drivetrain warranty to match the dealer. Improve the look and capability of your 2021 Ford F150 with these first to market 4" or 6" lift systems from BDS Suspension.

Hey Daniel,
While there is some crossover with the chassis/suspension design from 2015-2020 F150 over to the 2021 models, there are several differences that needed to be addressed for our 2021 lift kits. These trucks use a new steering knuckle and sway bar design along with new upper control arm, differential brackets and a few other minor changes. These kits are on the shelf and ready to go for the 2021 F150 models

Hey Jordan, two setups on our test F150.

(black wheels)
BDS 4″ lift kit, 35×12.50 Nitto Terra Grappler G2 tires on 20×9 Eagle Alloy 050 wheels

(polished wheels)
BDS 6″ lift kit, 35×12.50 Mickey Thompson Baja Boss tires on 20×10 Method 304 wheels

Hi, Just waiting on my ‘21 raptor come in, wanted to know if any of the systems on the F150 are affected. Specifically, the CoPilot 360, Trailer Backup Assist, or Park Assist

Hey Shane,
At this time we haven’t tested the ’21 Raptor variant. In general there are a number of minor differences that need to be addressed before releasing kits, with the intention being to retain full functionality of all the truck’s built in technology. Once we have kits ready to go we’ll send out a ’21 Raptor specific announcement and add them to our website.

We don’t plan to offer a basic 2″ (spacer) leveling kit for the 2021 F150s. Similar to the 2009-2020 F150s we will be offering 2″ FOX C/O UCA Kits in the future. Both the coilovers and upper control arms are new for 2021 and in development currently. Keep an eye out for upcoming announcements once available.

If you’re looking for a spacer leveling kit our sister company Zone Offroad offers has them available for the 2021 F150, check it out at F1205.

i just ordered a 2021 f150 platinum power boost engine, 4×4.
I have several questions for you before deciding which kit to buy.
First I order wheel well liners front and rear. If I use the 12.50 x 35 tires and rims and the 4″ kit will the tires rub anywhere?
Can you tell me what tires and rims are on the black truck in your video? I would like to use 18″ rims because I think there is more rubber on the side walls and the truck rides smoother. I don’t want tires that sing bad. I used Goodrich KO2 on my raptor and they were great.
My next question is what is the difference between regular shocks and coil overs as far as the benefits and ride quality?

I really want to make sure when I buy tires rims and 4″ lift that everything works good and no rubbing or other problems, especially with Ford and warranty by me changing the front end. I want to make sure I have the proper rim and backspacing. I am not sure if the Power boost engine and front end are the same as the eco boost or 5.0 liter. Since the trucks are all new

Hey Wayne,
Thanks for your interest in BDS and congrats on the new truck. You had a number of questions in there so to start off wheel/tire clearance. We list our recommended wheel/tire dimensions with each kit, however true tire sizes vary slightly by manufacturer and to maximize the shape of the factory wheelwell it is common to do minor trimming, especially to help optimize the wheelwell shape with oversized wheels/tires, or if the truck is used offroad (cycling the suspension more than if only used on road) or you plan to install fender flares, etc. Our 4″ kits allow use of 18″ aftermarket wheels, the recommended spec is 35×12.50×18 tires on 18×9 wheels with a 5″ backspacing. The truck with the black wheels is running the 4″ kit, 35×12.50 tires and 20×9 wheels (5.5″ backspacing). BFG KO2 is a great tire so if you had success with them in the past I’d say go for them on this truck.

Standard (strut spacer) lift kits vs coilover kits. Ultimately the strut spacer will retain the factory ride quality due to the factory strut being reused. While these provide a decent on-road ride, they have their limitations when used for high-speed offroad driving. The FOX coilovers offer improved damper performance, adaptability to various on/off-road terrains and adjustability. If driven 100% on-road you wouldn’t be taking advantage of all the FOX coilover features, mainly just the high-end appearance. If you plan to use the truck offroad, that’s where you’ll see the benefits of the upgrade. Something to keep in mind, we do sell the coilovers separately so its something you could always upgrade later.

Last topic, warranty. All of our kits include Factory Protection Plus, which provides you with BDS’s No Fine Print Warranty on our parts, FMVSS No.126 (ESC System) compliance testing, and a 5-year 60,000-mile drivetrain warranty to match the Ford warranty in the event you have any issues.

If you have any other questions feel free to reach out to our sales team or head to your local BDS dealer

What about the 20x9s on the 4” lift.
Offset makes a big difference but it’s always a detail that’s left out

Hey Matt,
agreed on the importance of wheel specs. For a couple reasons we measure based on backspacing (BS) rather than offset. Offset is dependent on the width of the wheel and is more of a car term. Each manufacturer measures offset slightly differently which is why we list recommendations based on backspacing (BS) as it is provides a more critical measurement to ensure the backside of the wheel clears the steering knuckles used more commonly for trucks and is not dependent on the width of the wheel. For the 4″ kits our recommendation is to use a 35×12.50 tire on 20×9 wheels with 5.5″ backspacing (BS) for optimal clearance. That said other 20″ wheels with smaller BS measurements can be used, it will just affect tire clearance to the fenders.

There are a number of sites that help convert from offset to backspacing, one we like is calculator.

Hey Gilbert,
This particular kit is designed for 4WD models only as it includes diff drop brackets/diff skidplate. We haven’t test fit parts on the 2WD models to configure those kits. While it may fit (Ford typically uses the same chassis/suspension design between 2WD/4WD applications), its not one we’ve officially approved for use at this point.

hello I am about to purchase a 2021 lariat 4×4 super crew, I was wondering if I could put on a 6 inch lift with some 26×14 inch fuel wheels? also do you make the custom trail arms for the 2021s yet

Hey Rod,
Our wheel/tire recommendations are just that, recommendations, based on what we’ve test fit. Other sizes can be used like the 26×14 wheels you mentioned, but you need to understand that will affect tire clearance and likely require additional trimming to allow clearance when turning. At this point the kits and coilovers are available, the skid plate, upper control arms and other accessories are still in development at this point and can be upgraded later.

Hi,

I am trying to order a few kits to lift trucks for our lot but the company we are buying them from is saying that they are not compatible on trucks with the ccd suspension that comes standard on lariat and higher trims levels? We are in Canada and so these trucks have just arrived and we are not getting very clear answers so any helo would be great. we wants to install the 6″ BDS kit.

Thanks

Hi Craig, sorry for any confusion. At this time we are not offering kits compatible with the CCD equipped 2021 Ford F150 4WD models, there is a note about it on our site (important notes). Engineering is working on kit variants for additional F150 trim models, that said I don’t have an ETA on when hose variants will be made available.

I am getting ready to purchase a 4″ coil over system for my 2021 f150. I think I prefer the Black Rhino stadium wheels in 18×9. Those come with a 12 offset and 5.4″ BS. I am hoping to put some 35×12.5 ridge grapplers on there. I love the look of your model truck shown with the 4″ coil over system and black wheels. Im just checking to see if there would be any issue with the particular offset and backspacing of the wheels I like. thanks!

Hey Ben,
Thanks for your interest in BDS and congrats on your new ’21 F150. The 4″ C/O system is a great option to correct steering/suspension/driveline geometry, while offering great on road handling and impressive offroad performance. When installing the lift kit, the replacement steering knuckles move the steering mount up to maintain handling, ESC compatibility with the factory steering rack which can limit wheel options, especially for smaller diameter wheels. For 18″ wheels we spec 18×9 with 5″ backspacing to allow sufficient clearance to the tie rod ends mounted into our steering knuckles. If your wheel has 5.4″ backspacing you will likely need about a 1/2″ wheel spacer to achieve that spec.

Does the 6″ kit increase the turning radius on the 21 Powerboost? My 2018 F150 has another brand lift and it greatly increased it making u-turns impossible. Thanks

Hey Mark,
in general our aim is to maintain the turning radius before/after the lift is installed. On the late model F150 kits there is zero track width increase and with the steering stop in the same location this kit the turning radius is vary similar to as the truck was stock.

Just got my 2021 King Ranch with the 20 inch rims. I would like to use the stock rims and add 35 inch tires with your 4inch lift. What tire size do you recommend? With a 295/65/20 work? Or could I use a 35 x 12.5 ?

Hey Jake,
congrats on the new truck. Factory 20s can be reinstalled with out lift kits, we recommend up to 305/60r20 tires to allow sufficient steering clearance.

Hi,

I have a 2021 F150 Lariat Powerboost SC LB and want to lift the truck but I’m at an impasse for what to do about a 2″ lift and not necessarily needing a 4″ lift. The 2″ works well for me but only a couple brands are making a coilover setup right now and I really don’t want to use a spacer since the 2021 (vs my 2019 platinum) seems squishy with lots of body roll.
99% of my driving is on road with most of it being highway so (as you’ve said in previous comments) the BDS lift would be more glam on the truck and never quite fully be taken advantage of.
Do you expect BDS to release a 2″ coilover setup? I would particularly be interested in not replacing my LCAs or UCAs.
I would really appreciate the help narrowing down my options.

Thank you,

Hey Brandon,
We have a few 2″ coilover setup in the works for the ’21 F150. Similar to our 2″ coilover options for the ’09-20 F150 we’ll have a few complete kits coming available soon that utilize front FOX coilovers, BDS UCA and rear FOX shocks to improve the offroad performance, handling responsiveness and on-road ride quality. In this case the FOX 2.0 Performance Series IFP loaded coilovers may be a better fit for your needs when they come available.

Hi,
I just bought a 2021 F150 Limited Powerboost and looking at doing a similar build to your F150 Limited project with BDS with a 4in lift.

My big concern is towing and payload, I need to retain towing capability and for some reason, although Ford lists on its towing chart that my specific truck/bed size/engine setup can tow 11,000lbs, and payload should be 1830 lbs, the sticker in the door frame shows actual payload is only 1353 lbs!!! I don’t know why that is (powerboost batteries eating up all the payload?) and Ford dealer is not forthcoming with an answer. So I need to conserve, if not increase payload back to 1800+ lbs… can you please clarify how your lift kits affects towing and payload capacity, and if you can help me in any way to resolve this issue with your kit or other add-ons?

Thanks as I really like your kit and also need to find a towing/payload solution.

Stephan

Hey Stephan,
Thanks for reaching out and your interest in BDS. Similar to the setup on the Work/Play F150 our 4″ kits retain the factory leaf springs and utilize a 3.25″ rear lift block that replaces the factory 1.25″ rear block and level out the stance once lifted. Ultimately that won’t have much, if any affect on tow/load capacity, but the tire/wheel setup you choose might if they have a lower load rating.

On the additional improvements we did on our F150 to improve load capacity and towing performance we opted for the Ridetech LevelTow system. This air-bag setup is connected to a compressor and uses a ride height sensor to automatically adjust pressure in the bags based on how the bed is loaded down. There are other air bag setup on the market, but we’ve had great success with these Ridetech kits the last couple years.

Hope that helps, if you have any other questions feel free to reach out to our sales team (517) 279-2135 or stop by your local BDS dealer.

My 2021 Ford F150 Platinum will be in soon. I want to install a 6″ lift and new tires and wheels. No off-road driving. I’m told BDS is the only 6″ lift available at this time. On my 2018 I installed Cooper, Discoverer AT3, 35X12.5R20LT tires and they rode well down the freeway so I will install the same again. New rims will be 20’s and I will let the tire shop figure out how wide. What off-set should I ask for front and back? Any issues I should be aware of for the 2021 F150 Platinum? Thanks

Congrats on the new truck Floyd, we’re loving our ’21 F150 Platinum with a similar setup. We list our recommended wheel tire spec on our website as well as in the instructions. These are just recommendations as other tire/wheel specs can be used.

6″ Lift Kit on 2021 F150 we spec:
35×12.50 tires w/ 18×9 wheels (4.5-5″ backspacing)
35×12.50 tires w/ 20×9 wheels (4.5-5.75″ backspacing)
37×12.50 tires w/ 20×9 wheels (5.5-5.75″ backspacing)

Will the lane centering, adaptive cruse and future auto pilot on the F-150 still all be fictional? Will any recalibration be needed for the sensors?

Hey Mark,
Thanks for your interest in BDS. To answer your question everything will function as it does from the factory once the lift is installed. No recalibration is required unless the battery was unhooked for too long, but that’s not related to the lift itself.

Can the 2″ kit be installed on a 2021 PowerBoost Platinum? 4 Wheel Parts wasn’t able to install a leveling kit on my PowerBoost. They said some of the hybrid components prevented installation?

Will the 2″ kit with 35″ tires interfere with the Co-Pilot 2.0 or the Hybrid functionality?

Hey John,
At this point we haven’t released the 2″ kits for the 2021 models including those with the PowerBoost, but we have options in the works that will be similar to our offerings for the 09-20 F150 models coming available soon. Kits will retain all vehicle functionality and factory systems. Once kits officially launch we’ll have more info available.

I noticed the post about the 2021 2WD F150 lift from before. Have you tinkered with it yet or heard if the 4wd lift will work on the 2WD?

At this point we haven’t brought in a 2WD to confirm compatibility and make the 2WD updates to the BOM.

Hi, I am confused that it’s advertised to work with the factory ESC (electronic stability control) system, but the “import note” says it wont work with the CCD (continuously control damping) system, which is part of the ESC system. Just wonder how did you guys install the 4″ and 6″ lift on the F150 Limited (with CCD as standard option) in the demo video?

Hey Dominic,
No timeline at this point on the 2WD variants to the ’21 F150 4WD kits due to limited vehicle availability and focus on other applications currently.

Just purchased a 2021 Limited Hybrid and was curious if there was anything specific to the hybrid build that would make either of these lifts incompatible. Thanks!

I have a 2021 F150 Platinum and will soon have the 6” BDS lift installed that I located and ordered last weekend.

I have a question about my tire selection cause I know that it can take a 37” tire with the right spec, and most 35” tires are more like 34.5”.

Looking at a BFG KO2 in 325x60x20 which would be 35.4” tall and 12.8” wide. My wheels are 20” fuel beasts with 5.75” Backspacing. Would this fit correctly or am I too close with the extra .3” of width?

Hey Bill,
While we haven’t tested that particular wheel/tire combo on the new F150 I’ll say our recommendations are just that, recommendations. Additional wheel/tire specs can be used and will ultimately depend on other mods made to the truck that may affect tire clearance (fender flares, mud flaps, aftermarket bumpers), how you use your vehicle (on-road only vs cycling the suspension offroad) and your comfort level trimming if necessary. That said those are close to recommended specs and should go on just fine.

Hey, I recently purchased a 2021 F150 XLT 4WD and the setup I wanting to run was 37×13.5r24 – 24x12s. Is that possible if so, how much trimming would be needed / would it be recommended.

Hi Dan,
Ultimately that tire/wheel combo is outside of our recommendations for the new F150 and their would likely require a fair amount of trimming to for clearance in all driving situations (on/off-road).

Just purchase a 2021 f150 with all the cameras and those features. I’m installing a 4 inch lift. Does it need recalibration or not

Hello,

Will 17×9 Fuel rims on 35/12.5/17 Fuel Tires work with the 4″ BDS Lift kit?

Thank you,

Hi Christian, due to the steering mount positioning on the new knuckles for ESC compatibility this kit requires 18″+ wheels.

It looks like the new F 150 Limited’s are coming with CCD standard now. It is an option in all other trim levels. Has BDS come up with a 4″ kit that is compatible with CCD, or do I need to focus on a different trim level?

Hey Jake, we’ll have some additional lift heights available for the 2021 F150 in the future, keep an eye out for upcoming announcements.

Hey Andrew, while we do plan to offer 2WD F150 variants in the future, there isn’t a timeline on when that will happen currently.

2021 ford F150 Platinum 4wd with PowerBoost engine and CCD. will your 4 inch coilover system work with this truck? see conflicting answers and no notes on lift kit details. i need a for sure answer before install. thank you

Hello just got a 2021 f150 lariat I ordered the 6”inch lift (1579f) I’m going with 37×13.50r20 tires on a 20×12 rim with a -44 offset I know I will need to do some trimming but other then that do you see any other issue ?

Hey Robert,
Ultimately that wheel/tire combo is outside of our official recommendations to clear on the 6″ lift kit. You’ll likely need to trim the bumper/valance, inner fender liner, and intrusion beams (aka crash bars) to allow sufficient clearance.

We plan to offer a kit for the 2WD F150 models, but at the point haven’t sourced a truck to compare check compatibility with our 4WD systems. If you’re interested in bringing your truck up to Michigan for test fit it is on our list of vehicles wanted for R&D.

Looking for lifts compatible with the F150 Tremor I have in order. I see the note stating the incompatibility.

What causes the incompatibility and do you plan on offering a kit specific to the F150 Tremor?

Hey Mike,
At this point we haven’t test fit kits on the F150 Tremor to confirm compatibility or make any adjustments. While the majority of there suspension is the same, we’ll need to verify prior to officially releasing, it is on our “vehicles wanted” list

Hey, I have the 2021 F150 limited powerboost with CCD and onboard scales. The rear shocks appear to be electronic. My local BDS dealer says your kit won’t work??? Right now they’ve put a 2” level on it and rides terrible. Shakes above 50mph and have tried to balance multiple times. Ideas?

Hey Wes, we don’t offer any kits compatible with the CCD-equipped F150 at this time. We have had limited access to the CCD-equipped F150 models to date to develop kit options, but you are welcome to contact our tech support team to see if they have any input on the issues you are experiencing, tech-bds@ridefox.com

We have any ETA on a 2wd 6inch lift yet for the 2021s? Rough country came out with their vertex one and I’m tempted but really want BDS. I’m impatient lol

I ordered a 2022 F 150 4×4 Limited in November 2021, which should be to me in March 2022. Will you have a 6 inch coilover lift that is compatible with CCD?

Hi James, congrats on the new truck. At this time we haven’t released F150 kits compatible with the CCD. Its on our list of kit variants to develop product for, but these trucks have been hard to come by so that will factor into the timing. We have 2021-2022 F150 w/ CCD on our list of R&D vehicles wanted.

2022 Powerboost Platty (4WD)
I work for Ford and several people have told me the Powerboost doesn’t have the same compatibility as a standard 2022 Lift Kit Non Hybrid? Can you confirm this? Or am I just good to order the 4 or 6 inch lift with no concern?

Hey Wes,
Does your truck have the CCD (continuous controlled damping) system on it? Many 2021 F150 Platinums didn’t, but we’ve seen it popping up more commonly with 2022 trucks. If it has CCD – see reference here, than our current kit offerings will not work on there. We have a call out to bring a 2022 F150 (w/ and w/o CCD) on our list of R&D vehicles wanted to confirm fitment and in the case of CCD trucks develop the kit variant for compatibility. If interested in using yours check out the online application to connect with our R&D team at https://blog.sporttruckusainc.com/vehicles-wanted/

Any update on the 6inch for the 2WD models for the 2021+ F150? Been waiting for almost a year. I’m on the list for R&D already and they haven’t said much.

Nothing to report at this time on the 21+ F150 2WD kits at this time from the sales/marketing side. That project is currently on the list within our R&D team among other projects. If they have a need for your vehicle for test fit and you’ve already submitted via the online form they may reach out. Once kits come available we’ll be adding the listings to our website and sending out an announcement.

I’m getting my 2021 f-150 lifted with the 4in BDS kit. The wheel i want is either a 5.04BS or 5.79BS. I really don’t want a lot of poke and my sweet spot is in between this 2 BS. Since the 5.79 is only .001mil more BS, will this cause issues?

Hey Edgar, That’s somewhat of a loaded question without knowing the full wheel/tire specs as the answer is somewhat dependent on the wheel diameter you go with, 18s we spec for a 5″ max backspacing which will allow sufficient clearance for the steering tie rod ends. 20s allow for clearance for the steering so we say you can use up to 5.75″ backspacing with oversized tires. The kit will allow for stock 20s (ie 20×8.5 w/ 6.5″ BS), but only with factory size tires as the wider tire setups begin to interfere with tire-to-suspension clearance.

If both wheels are 9″ wide, the 5″ backspacing will stick the overall wheel/tire combo out an additional 3/4″, but won’t be stuck way out of the wheel well. You shouldn’t have any issues on a 20×9 wheel with 5.79″ backspacing, but it’ll be dependent on the tires you choose. For more on this topic I’d recommend contacting our sales/tech support team at

Hi, I just bought a 2021 f150 lariat and had your 4” lift installed. I ordered 35×12.50×9 tires and rims with a offset of 24 I believe, but dealer says they don’t fit the truck. What modifications need to be made as your instructions says “some modifications may be needed”?

Hi Brad, we’d need additional info on the wheel/tire spaces to be able to give you feedback. A wheel offset measurement is dependent on the wheel width (not provided). Please provide the following wheel specs (diameter, width, and backspacing). Typically the modifications required consist of trimming to the inner fender, bumper, etc to ensure sufficient clearance in all driving situations.

I’ve been wanting a 6inch lift on my 21 2wd f150 for forever now. Could I use the 4wd kit and just not use the transfer case drop down brackets?
