We are proud to introduce our New Heavy-Duty Steel Blocks, precision engineered by our experts not only to lift your truck but to improve your ride quality and comfort as well as lifetime use. Each block is manufactured using only the latest in metal fabrication technology and finished with a Proprietary Powder Coating to ensure a level of protection and corrosion resistance that well exceeds today's automotive standards. Our Lift Blocks are constructed with 5/8th Center Pin to ensure stability, perfect fitment and easy installation.
We completed this kit with our newly designed set of Premium Forged Steel Flat-Top U-Bolts to safely secure your truck's rear suspension components. Supreme Suspensions Flat Top U-Bolts provide superior strength and axle position retention thanks to its improved mounting solution, especially designed for off-road and heavy duty applications. The Flat Top Design increases contact mating area with your vehicle's 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, 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.
* We do NOT recommend stacking the lift blocks. Our blocks are designed to be installed directly to your truck's factory suspension, between the axle and OE leaf pack, and then securing everything together using the included U-bolts.
