2x Front Lift Spacers2x Rear Add-A-LeafsInstallation Instructions*Will NOT fit vehicles with welded bump stopsOur Jeep coil spring spacer lift kits have been specially engineered to be one of the easiest and fastest lift installs on the market. Designed to work with your existing factory components, these spacers install with ease and involve no additional modifications to be made to your suspension. We've also incorporated an integrated raised lip into each spacer to ensure proper spring alignment and prevent slip-outs under harsh suspension angles. Our lift spacers are constructed from Delrin due to its high crystalline composition to provide superior strength along with enough flex to maintain your stock ride quality. Our kit will not dry up and deteriorate like polyurethane spacers. Supreme Suspension Add-a-Leaf rear lift kits are precision engineered to lift your truck and increase your towing capacity. Our leaf springs are formed from high-carbon, high-silicon steel which has been hardened and tempered to aid in spring shape retention. This ensures that the spring will not sag, or have its arc deform over time due to heavy loads or severe off-roading conditions. Depending on the condition of your spring pack, our add-a-leafs will raise the rear by 1.5-2".NOTES: An alignment is always recommended after altering the height of your vehicle.
