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

The BDS Suspension BDS1563FS / 1563H is an excellent method to lift your Ford F250 / F350 dually to allow for up to 37-inch diameter. These replacement arms are far superior to the factory-stamped steel units, built around heavy-duty radius arms that use 1-3/4" OD -10GA DOM tubing with support gussets. It features a high clearance design for extra ground clearance and is formed inward to allow for additional clearance of oversized tires. The arms correct the caster angle by bolting into the factory mounting points and repositioning the front axle.

BDS Pro-Ride front coil springs lift the front end 4 inches while maintaining performance and ride quality. A forged drop pitman arm and a supplied integrated drag link flip correct steering angles. The front axle remains centered using a 1/4" thick heavy-duty track bar drop bracket. Also included for the front suspension is a pair of sway bar relocation brackets, bump stop extensions, brake line relocation brackets, and an NX2 series steering stabilizer with a mounting bracket.

In the rear, the factory blocks are replaced by a pair of 4.5-inch lift blocks featuring integrated bump stop wings and e-coated extended u-bolts.
