BDS takes RAM 3500 4WD Trucks to the next level with 6" Radius Arm Suspension System - now available for trucks with Rear Air Ride.
Designed to improve the looks and performance of your RAM 3500, these kits include everything necessary to correctly lift them for improved offroad capability while maintaining on-road handling. The 6" kit will lift and level the stance with clearance for up to 37" tires. They use a pair of full-length progressive rate coil springs to provide extra height and smooth controlled performance. A forged drop pitman arm is supplied to correct steering angles along with an HD bar drop bracket to re-center the front axle. A pair of sway bar drop brackets to reposition the OE sway bar for optimal performance along with extended polyurethane bump stops to 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 bolt directly into the factory location. These new radius arms are a massive upgrade to the factory stamped units, using tubular construction and a lower cam adjustment to dial in the 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 5.5" 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, a 6" lift block and u-bolts are supplied to lift and level the stance along with heavy duty air bag spacer brackets for models equiped with rear Air Ride. This allows the rear suspension to 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.
