Superlift K1030FX 4 Inch Radius Arm Suspension Lift Kit with Fox 2.0 Reservoir Shocks

The Superlift K1030FX is a complete 4-inch coil spring suspension lift kit engineered specifically for the 2023–2024 Ford F-250 and F-350 Super Duty 4WD diesel. Designed using Original Equipment (OE) CAD data, this kit delivers a precise fit and maintains factory ride quality while adding serious ground clearance and an aggressive stance.

Up front, the lift height is achieved through diesel-rated engine-specific replacement coil springs that improve ride quality. Radius arm lowering brackets restore proper caster angle and alignment, while front compression travel-stop relocation brackets, a track bar relocation bracket, and a steering stabilizer bracket round out the front suspension package. In the rear, an HD fabricated steel block replaces the factory block, ensuring proper pinion and axle angles while reducing axle wrap.

This configuration includes Fox 2.0 Performance Series Remote Reservoir Shocks front and rear, delivering race-proven damping performance for both on-road comfort and off-road capability.
