BDS 6 Inch 4-Link Lift Kit Ram 3500 Diesel w/ Rear Air Ride 4WD (2013–2018)
Upgrade the stance, capability, and suspension strength of your 2013–2018 Ram 3500 diesel 4WD equipped with factory rear air ride with the BDS 6 Inch 4-Link Lift Kit. Designed specifically for air ride equipped trucks, this suspension system improves suspension geometry while delivering increased ground clearance and impressive off-road capability.
The front suspension replaces the factory radius arm setup with a heavy-duty 4-link conversion system, improving axle control and reducing caster change throughout suspension travel. This system uses high-strength control arms and ¼-inch steel conversion brackets, providing improved suspension stability and articulation under demanding conditions.
To achieve the lift height, the kit includes diesel-specific Pro-Ride progressive rate coil springs engineered to provide consistent lift while maintaining a smooth and predictable ride across varying terrain conditions. These springs are manufactured from high tensile steel to ensure durability and long-term reliability.
Steering geometry is corrected using a forged drop pitman arm and heavy-duty track bar relocation bracket, keeping the steering linkage properly aligned while ensuring the front axle remains centered through suspension travel.
Because of the increased ride height, proper driveline alignment is maintained with the included transfer case indexing ring and heavy-duty transmission crossmember, allowing continued use of the factory front driveshaft while correcting driveline angles.
In the rear, the system is designed specifically for Ram 3500 trucks equipped with factory rear auto-level air suspension, utilizing heavy-duty air bag spacers, lift blocks, and extended hardware to maintain correct ride height and suspension travel. The suspension is completed with NX2 Nitro Series shocks or optional FOX Performance Series shocks, providing improved ride control and off-road performance.
This complete bolt-on suspension system provides clearance for up to 37-inch tires, giving your Ram 3500
