Upgrade the stance and suspension capability of your 2019–2024 Ram 3500 4WD gas truck equipped with factory rear air ride using the BDS 5.5 Inch Radius Arm Lift Kit. Engineered specifically for trucks with the factory rear air suspension system, this kit delivers increased ground clearance, improved suspension geometry, and dependable off-road performance.
The front suspension utilizes gas-specific Pro-Ride progressive rate coil springs, designed to deliver the correct lift height while maintaining a smooth and predictable ride across a variety of terrain conditions. These high-strength springs are built from premium tensile steel and engineered to maintain consistent performance without premature coil bind.
To improve suspension durability and handling, the factory stamped steel radius arms are replaced with heavy-duty tubular radius arms. These arms mount directly in the factory locations and provide caster adjustment to maintain proper alignment at lifted ride heights while utilizing OE-style rubber bushings for quiet and maintenance-free operation.
Steering geometry is corrected using a forged drop pitman arm paired with a heavy-duty track bar relocation bracket, keeping the steering linkage and track bar properly aligned while maintaining accurate front axle positioning throughout suspension travel.
Because of the increased lift height, the system includes a transfer case indexing ring and heavy-duty transmission crossmember to maintain correct driveline angles and allow continued use of the factory front driveshaft.
In the rear, the system is designed specifically for Ram 3500 trucks equipped with factory rear air suspension, utilizing heavy-duty air bag spacers, lift blocks, and extended hardware to maintain proper suspension travel and ride height calibration. The suspension system is completed with NX2 Nitro Series shocks or optional FOX Performance Series shocks, providing improved damping performance and ride control.
This complete bolt-on suspension system increases ground clearance while allowing clearance for up to 37-inch tires, giving your Ram 3500 a more aggressive stance and enhanced off-road capability.
