BDS 8″ 4-link Systems for 2014-16 RAM 2500 Trucks

After more than a year of development, BDS Suspension is excited to announce the addition of 8″ 4-link suspension systems for the 2014-2016 RAM 2500 4WD diesel trucks adding to its seller lineup of 2″, 3″, 4″, and 5.5-6″ lift systems currently available. This new 8″ system has been meticulously engineered to improve the ride quality, stability and performance of your RAM 2500 with room for up to 40” tires. Up front the system utilizes the 4-link conversion and dual rate coil springs similar to the widely popular RAM 3500 8″ kits. In the back, the engineers developed a rear spring outboard kit with new coils to improve the trucks stability and ride quality.

As with all BDS kits, this new 8″ 4-link system is backed by Factory Protection Plus (FPP) giving you the piece of mind to use it and abuse it wherever your next adventure may be. FPP combines BDS’s No Fine Print Lifetime Warranty and a 5-year 100,000-mile drivetrain warranty.

For more information on the kit see below, head online to BDS Suspension or call (517) 279-2135.

BDS SUSPENSION SYSTEMS ARE PROTECTED BY THE FACTORY PROTECTION PLUS PROGRAM

Factory Protection Plus
  • 5-year, 100,000 mile drivetrain warranty
  • BDS’s exclusive No Fine Print Warranty

8″ RAM 2500 4-Link Lift Kits: BDS Suspension adds to its industry leading lineup for the late model RAM 2500 4WD trucks with 8″ 4-link systems. This new 8″ 4-link system offers premium on-road comfort and superior offroad capability for the best all around performance out of your new 3/4-ton RAM trucks. The system converts the factory radius arm suspension to BDS’s true and true 4-link design for improved stability, wheel travel, and handling across all terrains. The 4-link design limits caster change to less than 1-degree of change throughout wheel travel for better handling, steering control, and overall driveability. The heart of the system are a pair of massive frame-mounted brackets precision welded and engineered to position the new upper and lower control arms for optimal suspension geometry for late model RAM trucks. The 4-link brackets are fabricated from 1/4″ thick steel and wrap around the frame as well as the factory radius arm brackets to create an extremely sturdy mount for the new arms. Removal of the factory radius arm brackets is not required allowing the brackets to stay intact to speed up the installation time. The upper and lower control arms are built from 2″ OD x 3/16″ wall DOM tubing for the strength to take any abuse you can throw at them. They utilize large 2.5″ OD polyurethane bushings to isolate road vibrations and are formed inward to allow for extra tire clearance. These arms are finished in a durable textured black powder coating and use grease fittings for easy servicing.

The additional height comes from a pair of specially designed dual rate ProRide coil springs. These 8″ coils have been engineered and tested to improve the ride quality and performance across all terrains while holding up to the rigors that 3/4-ton truck owners demand without bowing or sagging over time. A heavy duty track bar relocation bracket is supplied to recenter the front axle once lifted and a forged drop pitman arm is used to correct steering angles to keep them in phase for proper handling. New extended sway bar links are included to correct the front sway bar operating angle. These new links are greasable via pre-installed grease fittings and feature a unique poly-flex ball design to provide bind-free operation. Extended front bump stops are included to limit suspension compression and braided stainless steel kevlar-lined extended front brake lines allow full droop of the suspension. Rounding out the front are your choice of specially valved BDS-5500 or FOX 2.0 performance gas shocks for a smooth ride across any terrain.

At 8″ of lift, transmission/transfer case relocation is required to allow front driveshaft functionality. BDS includes a new laser cut transmission crossmember and adjustable transmission mounting plate to increase clearance front driveline clearance. The transfer case is repositioned by way of a supplied indexing ring kit to correct the operating angle and a billet aluminum driveshaft spacer is supplied to allow the use of the factory driveshafts. Indexing rings are available for both 6-bolt and 8-bolt transmission equipped trucks, confirm transmission before ordering.

In the rear careful consideration was taken to design the system for load carrying capacity, handling, and ride quality. The factory coil positioning inside the frame rails is sufficient at smaller heights, but at 8″ of lift needed to be modified to increased stability. The engineers developed an all new outboard coil spring design that relocates the coil spring position outward 8″ on each side (16″ total) using a set of bolt-on mounts. This new position mimics that of a leaf spring on the 3500 models and provides increased stability without compromising ride quality. The new upper and lower coil seats locate off of existing features on the frame and axle, requiring only minor drilling for mounting hardware. The new position allows for a much shorter and more stable coil spring design. This virtually eliminates any chance of coil bowing and ensures the coils react predictably throughout the full range of travel. In addition to the coil springs/mounts, a new track bar relocation system is included to properly set the rear roll-center height and center the axle under the vehicle. The rear track bar relocation includes a new heavy duty adjustable track bar. The track bar uses high-durometer polyurethane bushings at the frame and an adjustable forged COM bearing joint at the axle. Extended rear sway bar links round out the rear suspension components. Rounding out the rear of this kit is your choice of BDS-5500 or FOX 2.0 performance gas shocks.

Get your new RAM 2500 ready for the trail with BDS Suspension. For more info on this new 8″ 4-link suspension system and available accessories, visit BDS Suspension or call (517) 279-2135.

Available Accessories:
BDS has a number of accessories available to fit the new 2014-2016 RAM 2500 trucks to compliment the new 8” 4-Link System. Both single and dual steering stabilizer kit are available to meet your on-road and off-road performance needs. Available with 5500-series (white body), 9500-series (brushed stainless body), and FOX 2.0 (50/50-valved aluminum body) BDS steering stabilizers improve drivability by reducing front end shimmy caused by oversized tires and mount above the tie-rod for extra protection when offroad. The dual stabilizer kits mount end-to-end with an attractive BDS branded center bracket. In addition to steering stabilizers, BDS offers a heavy duty adjustable front track bar to allow you to dial in the front axle lateral positioning. Constructed from 1-3/8? solid steel stock this new adjustable track bar is built to handle on and off-road abuse and uses a 1-3/8?-12 fine threaded pinch bolt design turnbuckle to allow easy tuning to properly recenter the front axle for a range of lift heights. The track bar is formed for proper clearance around critical front end components and features gusseted ends for additional rigidity. The ends utilize high-durometer polyurethane bushings with thick-walled steel sleeves for strength and reliability. Along with the FOX 2.0 IFP shock upgrade, BDS offers front dual shock mounting brackets to improve dampening. The upper hoop ties into the factory coil bucket and frame rail for added rigidity and allows you run a pair of BDS-5500 or FOX 2.0 shocks at each front corner. If you’re looking to improve your RAMs flex out on the trail, BDS offers a sway bar disconnect upgrade kit to convert the front links supplied in the 8” system. Lastly, BDS offers several components to improve the driveline angle and eliminate potential driveline vibrations. In addition to the t-case indexing ring kit and crossmember supplied with the kit, BDS offers carrier bearing drop kit and rear billet aluminum driveshaft spacer. Enhance the performance of your 8” 4-Link System equipped RAM 2500 with accessories from BDS Suspension and FOX.

    good afternoon. I like to ask you to send me copies of certificates, licenses, contracts with companies for the installation of a lift kit, RAM. In Russia, there are problems with the law by installing a lift kit, I want to get permission. I need all the copies of the documents for your products, certificates. Thank you.

    Is there anything in the works for the hemi-powered Ram 2500’s?

    Reply
    • Carter @ BDS Suspension says:

      Hey Jesse,
      The short answer is yes with some modification. The largest kit we offer for the gas RAM 2500 is the 5.5” 4-link. We don’t offer an 8” front coil spec’d for the weight of the hemi, and installing the diesel springs will likely net about 9.5” of lift (we advice against going that tall because it will cause driveline and alignment issues). The base 8” kit components could be used in conjunction with the 5.5” gas coils in addition to our 2” coil spacers to net around 7.5” lift and a smooth ride quality, another solution could be to run out 6” diesel coils to net roughly 7.5” as well. While we haven’t tested this exact setup on a gas truck, we know from other Hemi RAM 2500 installs that driveline modification may be needed once installing the lift. Also, if equipped with the 6.4L Hemi, extensive exhaust modification will be required for the exhaust to clear the 4-link brackets. For more on the topic contact our sales/tech team at (517) 279-2135.

    Carter, I sent an email in to the sales team link that you posted above. I’m looking into what it takes to be sponsored by BDS, I’m currently running a 5″ Rough Country Suspension lift but would really like to get in with the big dogs, however, cost is always an issue. I’ve been working on a 2014 Ram 2500 little at a time with the help of some local companies. Would you have any input or someone I can speak to in regards to this matter?? Marketing Maybe?? If you can send me am email I’d like to communicate with you further. Thanks for any help.

    Do you know if the 8″ is to big (IE Illegal) in the great sate of CA? I am picking up a new Ram 2500 Mega Cab and don’t want to worry about being pulled over by the Nazi’s every time I drive this rig. I want the 8″, but may have to go the 6″?

    Reply
    • Carter @ BDS Suspension says:

      Hey Mike, each state has different lift laws and we don’t claim to be versed in them all. There are a number of websites and forums that discuss lift laws, a quick search pulled up this, http://www.liftlaws.com/california_lift_laws.htm. I’m not sure the accuracy, but you cross check it with other sites and even check with local offroad shops on the topic

  • Mike says:

    Thanks Carter, I actually found the exact site today. It looks like I can basically be 31 inched from the ground to the bottom of the frame. You wouldn’t have happen to have measured any of the rams running this kit would you?

    Reply
    • Carter @ BDS Suspension says:

      That’s not a measurement we take, but a good estimate would be to take the stock frame rail measure, then add 6” or 8” (for the lift), plus 1/2 the difference in tire sizes (i.e. stock 33” tires to 38” tires will raise the frame height roughly 2.5”)

    Hello, March of 2015 I bought your 6″ long arm kit for my 2015 Ram 2500. I limited myself to only your products due to my knowledge of BDS quality. By limiting myself to your products I also thus limited myself to a 6″ lift. Now less than a year later you have an 8″ kit out… Are some of the parts the same what do I need to turn my 6″ kit into the 8″ that i would have purchased if it was available? Thanks Ed

    Reply
    • Carter @ BDS Suspension says:

      Hey Edward, we appreciate the loyalty. Much of the front 4-link kit and t-case indexing crosses over between the 6” and 8”, the rear however is different with our outbounded spring setup. The BDS sales/tech team will be able to give you a parts list based on your current setup. Give them a call at (517) 279-2135 or email at sales-bds@sporttruckusainc.com

    How about a 6-8″ kit for rear air ride 2500 cummins.
    There are 2 other companies out there who already have a kit that lifts 4.5″-5.5″….I would like a BDS. So please bring something out soon before I go ICON.

    I also have a 2015 RAM 4×4 Crew Cab Cummins 6.7 diesel with OEM rear air suspension. What do you offer in lift kits for this.
    Thanks

      Hey Remo, unfortunately we don’t offer an kits currently of the fact rear air ride equipped RAM 2500s at this time.

      Reply
      • Mike says:

        So you would have to take the air ride out of the Ram 2500 to make the 6″ 4 link work? The only Ram 2500 diesels I can find all have air ride. I guess I can take the rear system out, but I wonder what kind of labor is involved to remove it?

        Reply
        • Carter @ BDS Suspension says:

          Hey Mike, at this point we’re not offering any kits for the air-ride equipped RAM 2500/3500 trucks. While I would assume the air-ride system could be removed and a standard kit installed, I can’t say whether or not the rear mounts are the same to accept the standard rear coils or how much labor is involved. You’re welcome to contact the BDS tech support team and discuss it further with them, (517) 279-2135.

    Hey Carter, I was wondering if you can tell me what differences there are in the 8″ setup to allow for different size tires. The black truck pictured above has 38×13.50″ Toyo Tires and the Silver truck has 40×15.50″ tires. Obviously the back spacing has something to do with it, I was just curious if you had a simple guideline I should follow as I’m going to order this lift for my 2015 Ram 2500 Mega Cab. I do a lot of towing in the 10,000lbs range and don’t want to over do it. I’m a huge BDS fan, I had your 8″ kit on my 2011 3500 Mega cab that was on 40×15.50 Toyos. I used the 8″ lift with your 2″ coil spacers but had to do extensive trimming. I’m currently running your 6″ kit on my 2014 Ram 3500 crew cab and have it on 37×12.50″ Nitto’s. Thank you in advance, I look forward to getting this kit on my truck!

    • Carter @ BDS Suspension says:

      Hey Brendon, thanks for reaching out to us. As far as difference between the white truck and the black one, the suspension is identical, the owners just chose to run different size tires on them. For reference to your old RAM, while they look the same the new suspension design on the 2014+ sits about 2” taller than the older trucks so this 8” system will sit at the same height as your previous 10”. In the case of the white RAM 2500 the 40×15.50×20 tires on 20×10 (4.5” BSing) wheels were a bit large on that truck and did require some trimming for clearance when turning full lock or using the truck offroad. The black truck had plenty of tire clearance in the fender running 38×13.50 tires on 22×10 wheels.
      The biggest thing for you will be finding a tire load rated high enough for weight that you tow, D works, but E would be ideal. I believe the 40×15.50 Nitto Trails and Toyo M/Ts are a D rating a which has worked well for us towing show trailers in RAMs on 40s, but an E rated 10-ply sidewall would be ideal if you could find them.
