Some vehicles are equipped with OEM 2" or 4" rear blocks. For these models, rear lift height will vary based on the size of the factory block being replaced by our lift block.

Developed and rigorously tested by in-house engineers, our rear blocks are precision machined from T6 Aircraft Aluminum and anodized to prevent oxidation & rust, ensuring a lifetime of dependability under even the most extreme riding conditions. These Rear Lift Blocks equipped with 9/16th Axle Locator Pins install simply and easily by placing the new blocks between your axle and OE leaf pack, and then securing everything together using the Heavy-Duty U-Bolts we included in this kit.

Supreme Suspensions newly designed set of Forged Flat-Top U-Bolts, ISO 9001 certified and stamped are guaranteed to satisfy the highest quality control standards. Forging process condenses metal grain structures, significantly increasing tensile strength, while the flat top design increases contact mating area with leaf springs, providing 10 times more clamping force compared to traditional U-Bolts. These U-bolts offer maximum safety by restoring the necessary clamping force on your spring assembly, eliminate flexing of the leaf spring packs and provide the desired spring stiffness for your vehicle. 

NOTES: An alignment is always recommended after altering the height of your vehicle.
