4-Inch Lift Kit with Air Ride Support

The BDS Suspension 4-inch lift kit is engineered to elevate the performance, stance, and capability of 2014-2018 Ram 2500 diesel trucks equipped with factory rear air ride. This comprehensive system allows for the fitment of up to 35-inch tires, transforming your truck's off-road and on-road presence. Up front, the kit includes diesel-specific, progressive rate Pro-Ride coil springs crafted from high tensile steel for a reliable and smooth ride. Heavy-duty tubular radius arms replace the factory units, offering improved strength, caster adjustment for optimal alignment, and OE-style rubber bushings for quiet operation. Steering geometry is corrected with a forged drop pitman arm and a heavy-duty track bar drop bracket to maintain proper phase through suspension travel and recenter the front axle. Additional front components include sway bar relocation brackets and brake line brackets. The front driveline angles are also corrected with an HD transmission crossmember and t-case indexing ring, allowing the use of factory driveshafts. In the rear, the kit utilizes heavy-duty air bag spacers and a track bar relocation bracket to ensure correct axle positioning. This ensures the vehicle's electronic suspension systems operate as intended. Buyers can choose between two shock options: the NX2 Nitro Series, featuring a nitrogen-charged, twin-tube design with 10-stage velocity-sensitive valving and a 1-3/8-inch high-flow piston, or the FOX 2.0 Performance Series, boasting a 2-inch impact extruded aluminum body, internal floating piston (IFP) monotube design, and a massive 5/8-inch hard chrome-plated alloy steel shaft. Both shock options are tuned to enhance ride quality and off-road performance.
