4″ Radius Arm Systems | 2020 Ford Super Duty | NPA #370

PR372-1

The next generation 2020 Ford Super Duty is here chocked full of cool tech and a new 10-speed transmission. While the suspension carries over many similarities to the 2005-2019 model Super Duty, a few kit updates have been needed to ensure the fit and finish BDS customers have come to expect. The first kits to be officially launched for the 2020 Super Duty are 4" radius arm systems, available for gas and diesel trucks as well as offered with NX2 shocks, FOX 2.0 shocks, FOX 2.5 RR coilovers and FOX 2.5 DSC coilovers. Joining these 2020 compatible lift systems soon will be a wide range of 2-8" lift systems as well as some additional kits and options. These 4" radius arm systems will allow clearance for 37" tires to be installed. As with all BDS kits these include Factory Protection Plus (FPP) for peace of mind wherever you adventure. Included in FPP is BDS's No Fine Print Warranty and a 5-year, 60,000-mile supplemental drivetrain warranty. Improve the performance, capability, and curb appeal of your new 2020 Ford Super Duty with BDS Suspension.

Coldwater, MI: BDS Suspension adds new lift options and accessories for the 2020 Ford Super Duty. These 4” radius arm systems are the first of many options for these new trucks.

4" Radius Arm Lift Systems:

Built to take full advantage of the factory suspension design, these 4" radius arm systems correct suspension, steering, and driveline geometry with room for 37" tires. At the heart of this system is a pair of heavy duty radius arms built to withstand whatever abuse you can throw at them. Built from 1.75" OD -10GA DOM tubing with support gussets, these replacement arms are far superior to the factory stamped steel units. They use a high clearance design for extra ground clearance and are formed inward to allow for additional clearance of oversized tires. They incorporate factory style 3.25" rubber bushings to minimize road vibrations and allow for a long, maintenance-free bushing life. The arms bolt into the factory mounting points and reposition the front axle to correct caster angle. The additional 4" of lift comes from a pair of full length diesel of gas specific ProRide coil springs. These paired with your choice of BDS NX2 series gas shocks or the precision tuned FOX 2.0 performance gas shocks offer a smooth ride and improved control over rough terrain. To improve steering angles, a forged drop pitman arm is supplied with an integrated drag link flip. Used in combination with the 1/4" thick heavy duty track bar drop bracket will position the front axle and keep the track bar angle in phase with the steering for improved handling. Also included for the front suspension are a pair of sway bar relocation brackets, bump stop extensions, brake line relocation brackets and a NX2 series steering stabilizer with mounting bracket. Out back a 4.5" fabricated block with integrated bump stop wing is used in place of the factory block on the F250 or F250 to level the stance. Longer black e-coated u-bolts and your choice of NX2 or FOX 2.0 shocks round out this 4" radius arm lift system.

4" Radius Arm Coilover Systems:

Built to take full advantage of the factory suspension design and take performance to the next level, these 4" radius arm coiler systems correct suspension, steering and driveline geometry with room for 37" tires.

Built from 1.75" OD -10GA DOM tubing with support gussets, these replacement arms are far superior to the factory stamped steel units.

They incorporate factory style 3.25" rubber bushings to minimize road vibrations and allow for a long, maintenance-free bushing life. The arms bolt into the factory mounting points and reposition the front axle to correct caster angle. The additional 4" of lift comes from a pair of specially tuned FOX 2.5 factory series remote reservoir coilovers. Available with or without the optional DSC (dual speed compression adjustment) these coilovers are preset right out of the box for optimal performance with the weight of the 6.7L Powerstroke diesel engine. They are an easy install using the supplied frame and axle mounting brackets and pair with FOX 2.0 performance gas shocks offer a smooth ride and improved control over rough terrain. To improve steering angles a forged drop pitman arm is supplied with an integrated drag link flip. Used in combination with the 1/4" thick heavy duty track bar drop bracket will position the front axle and keep the track bar angle in phase with the steering for improved handling.

Hi I have a 2017 f350 Ccsb platinum I am only looking for a
3-3 1/4” lift would just like to know if 2020 and 2017 4” coilover lifts are identical or are the 2020 ones 3/4”-1” lower in the front thank you so much for your time in this matter
Ultimately if they are lower I would like to put a 2020 lift on a 2017 with a rear 5” block to have a little rake thanks again

Hey Paul,
Base kits are the same between 2017-2019 and 2020-2021 Super Duty models, we use the same coilovers (or coils) between them all, the rear block height does vary. There is a slight height difference from the factory on these models with the newer models (other than Tremor models) sitting slightly lower from the factory which will affect net lift achieved. The ride height measurements we list are based off the 17-19 models. Our coilover options have some ride height adjustability and the radius arms have cam adjustment for 2-6″ of lift. On the rear block we offer several rear lift block options so you can set the stance of the truck to your liking. While our website isn’t set up to swap rear block options within a kit, it can be done easily enough by calling our sales/tech support team (517) 279-2135 or heading to your local BDS dealer to get you set up and place your order.
