We are proud to introduce our New Heavy-Duty Steel Lift 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.
The 1" Heavy-Duty Steel Blocks are constructed from one solid block of Steel, while the 1.5" and 2" 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!
These blocks are finished with a resistant black powdercoat to prevent oxidation and rust, ensuring a lifetime of dependability under even the most extreme riding conditions.
