Superlift 4" Lift Kit for 12-17 Jeep Wrangler JK 2 Door

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. Optional Front Sway Bar Links may be required.

Check out the optional AEV ProCAL Module, a great finishing touch to any lift kit as it can reprogram your vehicles computer compensating for gear ratio and tire size changes after lift kit installation not to mention many other additional features.
