4" 2020-2022 Ford F450 4WD 4-Link Lift Kit by BDS Suspension

BDS1223H / BDS1223FS / BDS1223FPE 4" 4-Link Lift Kit upgrades the suspension performance, stability, and ride quality of 2020–2022 Ford F-450 Super Duty trucks. Designed for heavy towing, hauling, and serious off-road use, this system replaces the factory radius arm suspension with a heavy-duty 4-link configuration that improves axle control, reduces suspension bind, and delivers smoother wheel travel throughout the suspension cycle.

The BDS 4-link conversion improves suspension geometry by maintaining more consistent caster angles and reducing anti-dive during braking. Heavy-duty ¼" steel brackets mount the high-strength upper and lower control arms to properly position the axle while limiting caster change throughout suspension movement. Full-length BDS Pro-Ride coil springs provide the correct 4" lift height while maintaining a smooth and predictable ride across varying terrain.

To correct steering geometry on lifted trucks, the system includes a forged drop pitman arm and a heavy-duty track bar relocation bracket to keep steering and track bar angles properly aligned while recentering the front axle. The kit is available with multiple shock options to match the desired performance level, including BDS NX2 Nitro Series shocks, FOX 2.0 Performance Series shocks, or premium FOX 2.5 Performance Elite shocks with DSC adjusters for precise tuning both on-road and off-road.
