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 tried 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 NX² series 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.
