4-Inch Lift Kit

The BDS Suspension 4-inch radius arm lift kit is engineered to enhance the stance, performance, and capability of your 2008-2010 Ford F250 and F350 Super Duty gas truck, providing clearance for up to 35-inch tires. This kit is designed for an easy, 100% bolt-on installation. Up front, the kit features gas-specific Pro-Ride coil springs for a smooth and predictable ride, complemented by heavy-duty tubular steel radius arms that correct caster and maximize ground clearance. Steering geometry is optimized with a forged drop pitman arm and a heavy-duty track bar drop bracket to maintain proper steering angles and recenter the front axle. In the rear, the kit includes high-strength fabricated steel blocks and a u-bolt flip kit for optimal pinion angles and increased ground clearance. Buyers can choose between standard NX2 Nitro Series shocks, featuring a nitrogen-charged twin-tube design with 10-stage velocity-sensitive valving and dual-welded ends for durability, or upgrade to FOX 2.0 Performance Series shocks. These FOX shocks offer an impact-extruded aluminum body, an internal floating piston monotube design, and application-specific valving for maximum performance. Recommended tire and wheel configurations include 35 x 12.5 tires with 18x9 or 20x9 wheels with 4.5 inches of backspacing. Trimming may be required.
