It's the same race-proven technology used by some of the toughest off-road competitors in the world, now built for your Ford F-250 or F-350. With everything pre-assembled and ready to bolt on, this kit delivers high-end performance without the hassle or wait time of a custom build.

Tuned Suspension Control With Durable Four Link Strength

This system brings together Superlift’s precision 4-link design with the legendary capability of King coilovers to create a suspension setup that is as refined as it is rugged. The 4-link arms are CAD-modeled and built from high-strength tubular steel, giving your truck enhanced suspension control through the entire travel range. Each arm uses heavy-duty REFLEX bushings that absorb vibration while maintaining flex and articulation in rough terrain. Up front, the King coilovers arrive fully assembled and ready to install, removing the need for spring compressors and simplifying the install process. A new track bar relocation bracket ensures that your steering stays tight and aligned, while the fabricated rear lift block replaces the factory block for a clean finish. The external reservoirs on all four King shocks improve cooling and performance, even under heavy use. Whether you're towing heavy loads or pushing your truck through tough terrain, this system is designed to stay composed, responsive, and rock solid.
