BDS Suspension 4 Inch Lift Kit w/ Radius Arm Ram 3500 Rear Air Ride 4WD Diesel (2019-2024)

Upgrade the stance, performance, and capability of your truck with the BDS Suspension 4 Inch Radius Arm Lift Kit for Ram 3500 diesel trucks equipped with factory rear air ride (2019–2024). Designed specifically for heavy-duty trucks with the factory auto-level air suspension system, this kit provides improved ground clearance, enhanced off-road capability, and excellent on-road ride quality.

Engineered as a complete bolt-on suspension system, this lift kit includes diesel-specific Pro-Ride coil springs, heavy-duty tubular radius arms, steering correction components, and precision-tuned shock options to ensure optimal suspension performance at the lifted ride height.

The upgraded tubular radius arms replace the factory stamped arms, providing increased strength and improved caster correction to maintain proper alignment. These arms mount directly into factory locations and use OE-style rubber bushings to deliver quiet operation and long-term durability.

To maintain proper steering geometry after lifting, the system includes a forged drop pitman arm and track bar relocation bracket, keeping steering components properly aligned throughout suspension travel while recentering the front axle.

Because lifting the truck changes driveline angles, the kit includes a transfer case indexing ring and high-clearance transmission crossmember, allowing the factory front driveshaft to be retained while improving driveline operating angles.

In the rear, this system is designed specifically for factory rear air ride equipped trucks, utilizing heavy-duty air bag spacers, extended hardware, and precision tuned shocks to maintain the functionality of the factory auto-level system while achieving the desired lift height.

Once installed, this lift kit allows clearance for up to 35-inch tires, improving both the appearance and off-road performance of your Ram 3500.
