Enhanced Suspension Performance with a True 4-Link Upgrade

Designed for 2019–2024 RAM 3500 4WD diesel trucks without rear overload leaf springs, the BDS 1692H 6" 4-Link Lift Kit delivers heavy-duty performance, superior ride quality, and aggressive off-road capability. This complete system replaces the factory radius arm setup with a robust 4-link conversion, improving articulation and minimizing caster change during wheel travel.

Built for Strength and Ride Comfort

The heart of this system is the 4-link conversion, which includes ¼-inch steel brackets and high-strength upper and lower control arms. This setup significantly enhances axle positioning, strength, and steering precision while allowing your truck to conquer tougher terrain with stability and control.

Optimized Geometry and Driveline Compatibility

The Pro-Ride coil springs are tuned specifically for diesel engines, and at 6” of lift, the forged drop pitman arm, track bar bracket, and transfer case indexing ring work in harmony to preserve steering angles and driveline function—allowing continued use of your factory front driveshaft.

Rear Suspension Setup

This kit uses 5" fabricated steel lift blocks, extended U-bolts, and NX2 Nitro shocks to lift the rear and maintain a level stance. The shocks are specifically tuned to work in tandem with the front suspension to ensure a consistent ride.
