BDS 4 Inch Lift Kit w/ Radius Arm for 2020-2022 Ford F350 Super Duty DRW 4WD Diesel

Key Features

• Easy, 100% bolt-on installation — installs into factory mounting locations for a straightforward setup.
• Pro-Ride dual-rate coil springs — full-length, diesel-specific springs deliver correct lift height and a remarkable ride across any terrain.
• HD tubular steel radius arms — replace the factory stamped steel arms, mount into the factory location, and offer caster adjustment across a range of lift heights. OE-style rubber bushings at the frame mount keep operation smooth, quiet, and service-free while maximizing ground clearance.
• Steering correction — forged drop pitman arm minimizes steering angle, paired with a heavy-duty track bar drop bracket to keep components in phase through suspension travel and recenter the front axle.
• Fabricated steel rear blocks — provide a level stance front to rear.
• Application-tuned shocks — standard NX2 Nitro shocks with vehicle-specific valving for better control, or upgrade to FOX 2.0 Performance Series for maximum on- and off-road performance.

Shock Options

NX2 Nitro Series: Nitrogen-charged, twin-tube design with 10-stage velocity-sensitive valving, dual-welded ends for increased strength, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish.

FOX 2.5 Performance Elite Series: Increased off-road capability with easy adjustment for terrain, load, and speed. Features a 2.5-inch impact extruded aluminum body, a 7/8-inch hard chrome plated heat-treated alloy steel shaft, an external reservoir that separates shock oil from high-pressure nitrogen, a standard Dual Speed Compression (DSC) Adjuster, and a fully serviceable design backed by a 1-year manufacturer's warranty.
