Configured with Nitro Series shocks front and rear. Nitro Series shocks feature an internal floating piston (IFP) monotube design with a large 5/8-inch hard chrome plated heat-treated alloy steel shaft, race-developed high-flow piston design, application-specific valving, and a long-lasting clear anodized finish.
Overview
This 4-inch radius arm lift kit is designed to lift and level the stance of the Ford F350 Super Duty DRW (2020–2021) 4WD Diesel, providing room for up to 37-inch tires. Front lift is achieved via full-length, diesel-specific coil springs paired with replacement radius arms. These arms are constructed from high-strength 1/4-inch steel, boxed and fully welded, with large 2.5-inch greaseable bushings to isolate road vibrations and improve ground clearance over drop bracket kits. A forged drop pitman arm corrects steering operating angles, while a heavy-duty 1/4-inch steel fabricated track bar drop bracket re-centers the front axle and keeps steering linkage angles in phase for predictable handling. Additional front components include sway bar relocation brackets, brake line drop brackets, bump stop extensions, and a single steering stabilizer kit. The rear retains the factory overload leaf springs and uses replacement lift blocks and longer U-bolts sized specifically for DRW models, along with a rear brake line bracket.
