Overview

This 4-inch radius arm lift kit from BDS Suspension is designed for the 2020–2022 Ford F350 Super Duty Dually (DRW) 4WD diesel truck. The kit improves stance, performance, and capability while providing clearance for up to 37-inch tires. Up front, the kit includes diesel-specific Pro-Ride coil springs, heavy-duty tubular replacement radius arms, a forged drop pitman arm, a track bar drop bracket for steering correction, sway bar relocation hardware, brake line brackets, and precision-tuned nitrogen-charged shocks. In the rear, the kit utilizes a high-strength fabricated lift block, longer U-bolts, brake line brackets, and a matched set of shocks.
