6-Inch Lift Kit

The BDS Suspension 6-inch lift kit with radius arms is engineered for 2014-2018 Ram 2500 diesel 4WD trucks equipped with rear air ride. This comprehensive kit is designed to significantly improve your truck's stance, performance, and off-road capability, offering ample clearance for up to 37-inch tires. Up front, the kit features diesel-specific, progressive rate Pro-Ride coil springs for a balanced lift and ride quality. Heavy-duty, high-strength tubular radius arms replace the factory units, offering caster adjustment and OE-style rubber bushings for smooth operation. Steering geometry is optimized with a forged drop pitman arm and a heavy-duty track bar drop bracket to maintain proper axle positioning and steering angles through suspension travel. The kit also includes bump stops, brake line brackets, and a choice of precision-tuned NX2 Nitro Series or FOX 2.0 Performance Series nitrogen-charged shocks. To address driveline angles at this height, a transfer case indexing ring and a new transmission crossmember are supplied, ensuring compatibility with factory front driveshafts. In the rear, the kit incorporates heavy-duty air bag spacers, a track bar relocation bracket for precise axle positioning, bump stop extensions, and sway bar links. It also includes new air ride leveling sensor brackets to maintain factory ride height functionality and full air bag range of motion. Recommended tire and wheel combinations for this kit include 37x12.50 tires with 17x8 wheels (5.625" backspace) or 18x9 wheels (4.5" backspace), as well as 35x12.50 tires with 17x9 wheels (4.5" backspace). Trimming may be required depending on tire and wheel selection.
