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 High-Strength Steel U-Bolts to safely secure your truck's rear suspension components. Our extended U-bolts rise to expectation by being ISO 9001 certified and stamped and exceed current standards in the auto industry. These U-Bolts are bent & threaded to exact specifications, and finished with an Electrostatic Powder Coating to ensure the maximum level of protection and corrosion resistance. Especially engineered for off-road and heavy duty applications, these U-bolts will restore the clamping force on your spring assembly, maximizing safety and ensuring that you get the most out of your rear lift.Note: *An alignment is always recommended after altering the height of your vehicle.
