Coldwater, MI: BDS Suspension expands its listings for the late model 2019+ RAM 3500 4WD diesel trucks with new 8" 4-link conversion systems that are on the shelf ready to ship. Designed to improve the look and performance of your new RAM, these new kits join existing 2"/3"/4"/6" lift kit options offering improved strength, capability and handling at a new taller lift height. Kits include everything necessary to correctly lift them for improved offroad capability with room for up to 40" tires while improving overall vehicle handling.

Up front these systems use a pair of 8" diesel specific progressive rate coil springs to provide the extra height and smooth controlled performance in the harshest of terrains. A forged drop pitman arm is supplied to correct steering angles along with an HD bar drop bracket to re-center the front axle. A pair of sway bar drop brackets reposition the OE sway bar for optimal performance along with extended polyurethane bump stops to limit up travel and brake line brackets to allow full droop. To correct the front suspension geometry at the new height, the factory stamped steel radius arms are converted over to 4-link using a pair of 1/4" steel brackets and high strength upper and lower control arms designed to limit caster control throughout suspension travel for more predictable handling characteristics. Also supplied are your choice of BDS NX2 gas shocks or FOX 2.0 Performance Series IFP gas shocks for improved ride and performance.

At 8” of lift it is critical to make front driveline adjustments to maintain use of 4WD due to the increased operating angle. To do this, BDS Suspension provides a heavy duty replacement transmission crossmember as well as a transfer case indexing ring to reposition the front driveline output which will need to be used in combination with an aftermarket front driveshaft (not included with kit). In the rear of the RAM 3500 kits a 5" block and add-a-leaf kit along with longer u-bolt for a level-to-slightly tail high while maintaing tow capacity. Finishing out the rear are a matching set of BDS NX2 gas shocks or FOX 2.0 Performance Series IFP gas shocks.

As with all BDS Suspension kits, these include Factory Protection Plus for a limited lifetime warranty, ESC System compatibility, and 5-year, 100,000-mile drivetrain warranty. Get the look and the ride you are after with these new 8” 4-link systems from BDS Suspension.

RAM 2500 w/ rear air ride - 6" BDS Systems: Since 2014 when RAM introduced the optional rear air ride suspension there has been a buzz over how it performs and curiosity about how it will hold up over time.  Both of those questions have been answered with years of use and abuse from truck owners with very few air ride system failures. With that success and the long term testing of new products by the BDS engineering department, we are excited to introduce the newest expansion into the air ride RAM market with new 6" lift options available for the rear air ride equipped RAM 2500 4wd diesel trucks.

Up front BDS Suspension offers (2) versions of this lift kit; the standard and the 4-link conversion. Both use a specially designed pair of progressive rate ProRide front coil springs for optimal performance across any terrain, heavy duty fabricated track bar bracket and forged drop pitman arm to correct steering geometry, extended bump stops and sway bar relocation and brake line relocation brackets to keep the suspension functioning properly. Also standard in the 6" kits a high clearance transmission crossmember and transfer case indexing ring kit are supplied to allow the stock driveshafts to be reinstalled. The standard 6" system retains the factory front radius arms and corrects the suspension geometry by  adding a pair of 1/4" steel frame-mounted drop brackets. The 4-link converts the factory radius arms over to a much stronger 4-link design for improved stability, handling and articulation. The 4-link limits caster change throughout wheel travel for much more predictable driving habits. It uses 1/4" steel brackets that key off the factory radius arm mounts for increased strength and use 2" OD x 3/16"-wall DOM control arms with large 2-1/2" OD polyurethane bushings for smooth, quiet operation. Rounding out the front are your choice of BDS-5500 series hydraulic or FOX 2.0 IFP gas shocks for improved performance.

In the rear both lift kits are designed to work with the factory rear air ride system. 1/4" steel, 5" tall gusseted air bag spacers are used along with a rear track bar bracket to correct axle positioning, extended length sway bar links, and bump stop extensions. BDS supplies new air ride leveling sensor brackets to position the ride height sensors at the stock angle. This allows the rear suspension to be perform just like it does at factory ride height and maintain full air bag range of motion. The rear suspension is rounded out with your choice of BDS-5500 hydraulic, BDS NX2 Nitro or FOX 2.0 performance gas shocks.

Along with these new systems, BDS offers several accessories including shocks and steering stabilizer kits, adjustable track bars, stainless steel brake lines and more. The 6" suspension systems allow for up to 37" tires to be installed. Upgrade your rear air ride equipped RAM 2500 with BDS Suspension.

Rear Adjustable Track Bar System for RAM 2500 Trucks

BDS Suspension expands its product lineup for the 2014-2016 RAM 2500 trucks with a new adjustable rear track bar designed to dial in the rear axle positioning. This new track bar provides improved control of the rear axle by replacing the soft factory rubber bushings in the OE track bar to a thick wall-DOM link with high durometer polyurethane bushings at the frame and a forged COM bearing joint at the axle. Can be used with or without track bar relocation when needed for lift heights from 0-8″.

For more information on this new adjustable track bar see below, head online to BDS Suspension or call (517) 279-2135.

#122609 Adjustable Rear Track Bar
While the engineers designed the new BDS 8″ 4-Link Systems for new RAM 2500 trucks, the need for a heavy duty replacement rear track bar became evident to recenter the rear axle and keep it under control in extreme conditions. As part of the rear track bar system the team designed a new rear track bar able to be used as both an OE replacement as well as to be integrated with track bar brackets. This track bar can be used with all BDS lift kits as well as most other kits on the market.

The new adjustable rear track bar uses a 1.75″ OD x .250″-wall DOM steel tube construction, fully welded with a greaseable from mounted end using high-durometer polyurethane bushings. At the axle mount, the track bar uses a steel forged end with fine 1″ threads for precision adjustments with a high load capacity COM bearing insert. The COM bearing uses an injection molded race for long lift and quiet operation. Its been precision machined for an exact fit to mimic the stock bushing allowing it to be used in the OE location as well as with aftermarket track bar relocation brackets. The track bar comes in a durable textured black powder coat finish and is ready for install right out of the box. Get your RAM’s rear under control with BDS Suspension.

Important Notes 
1) Must be used with an appropriate track bar relocation bracket for heights over 3″.

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.

  • 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.
