Coldwater, MI: BDS Suspension is now shipping suspension lifts and accessories for the rear air ride equipped 2013-2018 RAM 3500 4WD trucks. Available in 4" and 6" lift heights with either standard (drop bracket) or 4-link conversion and gas-or-diesel spec'd progressive rate coil springs these new RAM 3500 kits are designed to improve the performance, functionality, and curb appeal of your late model RAM 3500 while retaining the handling characteristics and functionality of your RAMs auto-leveling air bag system. All kits are offered with your choice of BDS NX2 series gas shocks or upgrade to the precision tuned FOX 2.0 gas shocks for superior performance as well as several optional accessories to include steering stabilizers, dual shock hoops, traction bars and more.

4" Standard Lift Kits: These standard kits are designed to retain the factory radius arms by relocating the frame mounting location using a pair of 1/4" steel drop brackets to maintain suspension geometry. The drop brackets key off the factory mounts and tie into the frame for extra strength. Also included in the kit are specially designed gas or diesel engine specific progressive rate ProRide front coil springs offering improved performance across all terrains. Also included is a heavy-duty fabricated front track bar bracket, forged drop pitman arm, extended bump stops, brake line relocation brackets, sway bar links, rear block and u-bolt kit along with rear air bag lower spacers and sensor brackets. Rounding out the kits is your choice of BDS NX² series gas shocks or FOX 2.0 performance gas shocks at each corner. These kits allow for 35-37" tires to be installed.

4" 4-Link Lift Kits: These kits are designed to convert the factory radius arm over to a stronger 4-link design offering improved stability, handling and articulation. The kit is designed with 1/4" fabricated 4-link brackets that key into the factory radius arm pockets for added strength. The 4-link design improves handling and drivability by limiting castor change to less than 1-degree throughout wheel travel. These kits also include gas or diesel engine specific progressive rate front ProRide coil springs, front and rear track bar brackets, a forged drop pitman arm, extended bump stops, brake line relocation brackets, sway bar correction, rear block and u-bolt kit along with rear air bag lower spacers and sensor brackets. Rounding out the kits is your choice of BDS NX2 series gas shocks or FOX 2.0 performance gas shocks at each corner. These kits allow for 35-37" tires to be installed.

5.5-6" Standard Lift Kits: These standard kits are designed to retain the factory radius arms by relocating the frame mounting location using a pair of 1/4" steel drop brackets to maintain suspension geometry. The drop brackets key off the factory mounts and tie into the frame for extra strength. Also included in the kit are specially designed (5.5") gas or (6") diesel engine specific progressive rate ProRide front coil springs offering improved performance across all terrains.

  • Dave says:

    I just installed the BDS 4″ lift kit on my 2020 Ram Rebel (non-air ride) and the rear sits about 1.75″ lower than the front. What could be causing that?

      Hey Dave,
      That’d be a better question to direct to our tech support team and see what info they need to help you get to the bottom of this. You can reach them at (517) 279-2135 or tech-bds@ridefox.com. You can also head to your local BDS distributor to have them look over the setup.
