BDS Suspension 5.5" 4-Link Suspension System for 2014-18 Ram 2500 4WD Gas Models w/ Rear Air Ride. Gas Only
The heart of this system is the 4-link conversion that replaces the factory radius arm. Key benefits include to doing this include increased stability, wheel travel, and improved 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. Included are a pair of massive frame-mounted brackets precision welded and engineered to locate the new upper and lower control arms to create the 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 allow the brackets to stay intact to speed up the installation time and make these kits reversible. 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 while repositioning the front axle slightly forward for increase tire clearance to the backside of the front fenders when turned. These arms are finished in a durable textured black powder coating and use grease fittings for easy servicing.
The additional front 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 3/4-ton 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 end 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 and allow you to reinstall your factory driveshafts.
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.
