BDS 5.5 Inch 4-Link Lift Kit Ram 3500 Gas 4WD (2013–2018)

Upgrade the stance, suspension strength, and off-road capability of your 2013–2018 Ram 3500 4WD gas truck with the BDS 5.5 Inch 4-Link Lift Kit. Engineered for improved suspension geometry and durability, this system delivers increased ground clearance and allows clearance for up to 37-inch tires while maintaining excellent ride quality both on and off the road.

At the front, the factory radius arm suspension is converted to a heavy-duty 4-link system, improving axle positioning and suspension stability while reducing caster change throughout suspension travel. The system utilizes high-strength ¼-inch steel conversion brackets and heavy-duty upper and lower control arms designed to handle demanding off-road conditions.

The lift system includes gas-specific Pro-Ride progressive rate coil springs, designed to provide the correct lift height while delivering a smooth and predictable ride across varying terrain conditions. Steering geometry is corrected using a forged drop pitman arm and heavy-duty track bar relocation bracket, helping maintain proper steering alignment and axle centering after lifting the vehicle.

Because of the increased ride height, the kit includes a transfer case indexing ring and heavy-duty transmission crossmember to correct front driveline angles and allow continued use of the factory front driveshaft.

In the rear, the system raises the vehicle using high-strength fabricated lift blocks and longer U-bolts, maintaining proper axle alignment while matching the front lift height. The suspension system is paired with NX2 Nitro Series gas shocks or optional FOX Performance Series shocks, improving ride control and off-road performance.

Designed as a complete bolt-on suspension system, this BDS lift kit provides improved suspension strength, enhanced off-road capability, and the aggressive lifted stance Ram heavy-duty trucks are known for.
