4" 2020-2022 Ford F350 Super Duty 4WD (Dually models) 4-Link Lift Kit by BDS Suspension

The BDS Suspension BDS1565H / BDS1565FS 4-inch 4-link arm lift kit for the Ford F350 dually allows for use of up to 37-inch diameter tires.  This awesome suspension system is designed to replace the factory radius arms with BDS's 4-link arm conversion. This will improve your truck's wheel travel, providing enhanced stability, strength, and caster control. BDS Pro-Ride front coil springs lift the front end 5 inches while maintaining performance and ride quality. The front axle remains centered with the use of a heavy-duty track bar relocation bracket. A forged drop pitman arm maintains proper steering angles.

In the rear, the factory blocks are replaced by a pair of lift blocks (size depends on number of main leaves in OE leaf springs) that feature integrated bump stop wings along with e-coated extended u-bolts. 

4-Link Conversion

This kit replaces the factory stamped steel radius arms with the BDS 4-link system to enhance suspension geometry, improving both handling and overall stability. This bolt-on upgrade utilizes heavy-duty 1/4-inch steel brackets to securely mount the robust upper and lower control arms, ensuring proper axle alignment and minimizing caster variation throughout the full range of suspension travel.
