We are proud to introduce our New Low Weight HD Structure Steel Blocks specifically designed for vehicles equipped with pre-installed factory lift blocks.

Using Heavy Duty GMAW Seam and Fillet Welding Processes we machined each lift block from 1-Piece CNC Formed Steel Frame and reinforced it's structure with 1/4" Thick CNC Plasma Cut Support Walls for maximum strength and stability. These Blocks are fabricated with Built-In Taper to Optimize Pinion Angles and preserve stock ride quality and 9/16th Axle Locator Pins to ensure stability, perfect fitment and easy installation. LAB Tests have shown these blocks can withstand an astonishing load of almost 60,000 lbs with no yielding or deformation observed!

These Lift Blocks equipped with 9/16th Axle Locator Pins install simply and easily by replacing the factory blocks installed between your axle and OE leaf pack.

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