BDS Suspension 2014-18 Ram 2500 4WD Gas - 5.5" Radius Arm Drop Suspension System. Gas Only
This 5.5" Radius Arm Drop System uses a pair of 1/4" thick steel radius arm relocation brackets to reposition the factory radius arms and correct suspension geometry and caster at 5.5" of lift. These brackets are designed for quick installation and create a stout mounting location for the radius arms by tying into both the factory radius arm frame mount and the side of the frame rails.
The additional height comes from a pair of specially designed progressive rate ProRide coil springs. The 5.5" coils have been engineered and tested to improve the ride quality and performance across all terrains while holding up to the rigors that heavy duty truck owners demand. A heavy duty track bar relocation bracket is included to recenter the front axle once lifted as well as a forged drop pitman arm to correct steering angles. Sway bar relocation brackets are used to reposition the front sway bar assembly and the supplied brake line brackets allow for the easy adjustment for the stock lines to be reused with the lift kit.
With the redesigned front suspension on 2014+ 2500 trucks, the 5.5" lift requires transmission/transfer case relocation components to allow the front driveshaft to function properly. BDS includes a new laser cut transmission crossmember and adjustable transmission mounting plate to increase clearance. The transfer case is repositioned by way of a supplied indexing ring kit to correct the operating angle of the front driveshaft.
In the rear, 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 NX² series or FOX 2.0 shocks.
