Coldwater, MI: BDS Suspension expands its listings for the late model RAM HDs with new 4" radius arm and 4-link systems for the rear air-ride equipped RAM 2500. Based on the popular BDS lift kits for the standard RAM HDs, these kit variants retain full functionality of the factory rear air-ride and on-road comfort while improving offroad capability.

[Radius Arm Kits] Up front these systems use a pair of progressive rate 4" 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 a HD bar drop bracket to re-center the front axle. A pair of sway bar drop brackets reposition the OE sway bar along with extended polyurethane bump stops to correctly limit up travel and brake line brackets to allow full droop. To correct the front suspension geometry at the new height a pair of heavy duty replacement radius arms are supplied to bolt in place of the factory arms. These new radius arms are massive upgrade to the factory stamped units, using tubular construction and a lower cam adjustment to dial in front end caster. 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 4" of lift it is critical to correct the front driveline angle to maintain use of the 4WD. 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 to allow use of the factory drivelines. In the rear, heavy duty air bag spacer brackets are used to level the stance 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.

[4-Link Kits] Up front these systems use a pair of progressive rate 4" 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 a HD bar drop bracket to re-center the front axle. A pair of sway bar drop brackets reposition the OE sway bar along with extended polyurethane bump stops to correctly 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.
