4-Inch Radius Arm Lift Kit

The BDS Suspension 4-inch radius arm lift kit is engineered to elevate the performance and capability of your Ram 2500 gas-powered truck, specifically for models equipped with factory rear air ride. This comprehensive system is designed to enhance your truck's stance and accommodate up to 35-inch tires, with options for larger 37-inch tires with potential trimming. Up front, the kit features gas-specific Pro-Ride coil springs for a progressive rate and smooth ride, complemented by heavy-duty tubular radius arms that offer caster adjustment and OE-style rubber bushings for quiet operation. Steering geometry is optimized with a forged drop pitman arm and a track bar drop bracket to maintain axle centering and minimize steering angles. To address driveline angles at this height, an indexing ring and a new transmission crossmember are included, allowing the use of the factory front driveshaft. The rear of the vehicle is addressed with heavy-duty rear air bag spacers, a track bar relocation bracket for proper axle positioning, and bump stop extensions. The kit offers a choice between BDS's NX2 Nitro Series shocks, featuring a twin-tube design with 10-stage valving, or FOX 2.0 Performance Series IFP monotube shocks, known for their application-specific valving and durable aluminum construction. Both shock options are nitrogen-charged to improve performance and off-road capability. This lift kit is exclusively designed for 2019-2024 Ram 2500 4WD gas models with factory rear air suspension. Trimming may be required for larger tire fitments.
