1988-1999 GMC K3500 Rear Add A Leaf Suspension Lift Kit 4WD 21.5" Short Add-A-Leaf

2x Rear Add-A-LeafsInstallation instructionsSupreme 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". This kit comes complete with high grade hardware including extended spring center pins.NOTES: An alignment is always recommended after altering the height of your vehicle.
