Billet Aluminum is premium choice material to use when leveling your truck thanks to the SOLID single-piece construction which yields extreme compression resistance, while still being light-weight and resistant to typical corrosion associated with off-roading.For lifting the rear end of your pickup truck we included our US Patent Pending Rear Lift Blocks. The 1" Heavy-Duty Steel Blocks are constructed from one solid block of Steel, while the 1.5", 2" and 3" Rear Lift Blocks are precision machined from ONE 1/4" thick plate of Steel, 3 times bend and precision welded using heavy-duty GMAW seam and fillet welding processes to ensure maximum strength and a lifetime of dependability under even the most extreme riding conditions. To maximize their strength and resistance to deformation, we reinforced the structure of these blocks with a 1/4" thick CNC plasma cut center support structure, completely welded to the frame.These blocks can withstand an astonishing load of almost 60,000 lbs with no yielding or deformation observed!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 it's 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.Note: *An alignment is always recommended after altering the height of your vehicle.
