The Superlift K905F is a complete 4-inch suspension lift kit engineered specifically for the 2007–2018 Jeep Wrangler JK 2-Door. This kit delivers 4 inches of lift while preserving on-road ride quality and dramatically improving off-road capability. It is packaged complete with Fox 2.0 shocks, purpose-built for the JK platform.
At the heart of this kit are pre-set, JK-specific replacement coil springs developed in collaboration with OE engineers. These springs minimize settling over time and guarantee a consistent ride height. The rear coils are rate-specific for the 2-door model, ensuring proper weight distribution and handling balance. The kit provides clearance for up to 35-inch diameter tires even during extreme off-road articulation.
Front track bar correction is handled by a new REFLEX adjustable track bar with forged ends and Superlift's lifetime-warranted REFLEX bushings — a dual-durometer design engineered to handle extreme angles while reducing noise, vibration, and harshness (NVH) compared to standard poly bushings or heim-joint ends. The adjustable length allows fine-tuning to accommodate winch bumper combinations and other front-end modifications. At the rear, a frame-mounted track bar relocation bracket corrects axle shift without steering geometry complications.
Compression travel is managed through unique machined aluminum receiver cups up front and replacement closed-cell foam dampeners in the rear. This kit is also compatible with the factory stability control program, making it a clean, factory-friendly upgrade.
