Our Blazer/Jimmy/Sonoma kit is perfect for lifting your truck reliably and easily. Precision machined from aerospace grad 6061-T6 aluminum, and anodized in a brilliant silver, our front coil spacers provide fastest, most hassle-free install, while maintaining your smooth factory ride quality. Supreme Suspension heavy duty steel lift shackles have been designed and built with quality in mind. 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″. This kit comes complete with high grade hardware including extended spring center pins.
