The JK family uses 22 different factory coil springs, each with a slightly different rate, dictated by how the JK is equipped. New Superlift front / rear coils provide the lift. The largest jump in spring rate is from the 2 to 4-door model so Superlift offers a heavier rated rear spring for the 4-door. Lift height can vary slightly (plus / minus up to 3/8") depending on your factory spring rate.

As the JK is raised, track bar angle increases and when lift height exceeds 2" bar length becomes an issue. Bar bind causes the chassis and axle to continuously "tug" against each other resulting in uneven ride height (side-to-side), chassis / frame misalignment and "roll and yaw". Front correction is accomplished via a new adjustable track bar. This route is preferred, as opposed to using a relocation bracket, since the bar's arc-of-travel must remain in-sync with the drag link's arc-of-travel or steering wheel "kick" will result. A relocation bracket is used on the rear axle since there are no steering geometry issues.

The stock JK has no provisions for front caster angle realignment, which is required at this lift height, so Superlift provides new alignment cams. Compression travel is controlled via new Urethane stops while new shocks (3 different levels of performance and price offered) improve control and restore full extension travel. The lift system also includes longer sway bar links with factory style, greasable tie-rod type upper ends, front / rear brake hose relocation brackets and emergency brake cable brackets... nothing is left unattended.

Optional upper and lower Rockrunner series axle-to-frame link-arms, constructed of .188" wall thickness DOM tubing, offer increased articulation. Urethane link eye bushings at the axle improve control while steel-encased rubber bushings at the frame ends prevent noise and vibration transfer. Other options include front sway bar quick disconnects, a replacement steering stabilizer, diff cover protectors and more.
