4-Inch Radius Arm Lift Kit

The BDS Suspension 4-inch radius arm lift kit is engineered to elevate the performance and appearance of your 2019-2024 4WD Ram 2500 diesel truck. This comprehensive system is designed to improve stance, enhance capability, and accommodate up to 35-inch tires. Up front, the kit features diesel-specific Pro-Ride coil springs for a balanced lift and progressive rate. Heavy-duty tubular radius arms replace the factory stamped steel components, offering increased strength and caster adjustability with OE-style rubber bushings for quiet operation. Steering geometry is optimized with a forged drop pitman arm and a heavy-duty track bar drop bracket to keep the axle centered. In the rear, progressive rate Pro-Ride coil springs are used, along with a track bar relocation bracket, bump stop extensions, and sway bar links. To address driveline angles at this height, the kit includes a high-clearance transmission crossmember and a transfer case indexing ring, allowing the use of the factory front driveshaft. Buyers can choose between three shock options: the nitrogen-charged NX2 Nitro Series with a twin-tube design and 10-stage valving, the FOX 2.0 Performance Series IFP monotube shocks with a 2-inch aluminum body and application-specific valving, or the FOX 2.5 Performance Elite Series shocks featuring a 2.5-inch aluminum body, external reservoirs, and Dual Speed Compression adjusters for enhanced off-road performance and serviceability. It is important to note that this kit will NOT fit air-ride equipped models.
