Universal Application Rear Lift Block 1.5 Inch Lift with 5/8 pin Pair Superlift

This Superlift rear lift block kit is a sold-as-pair set built from heavy-duty cast iron — a material choice that holds up under load far better than the stamped steel or aluminum blocks you'll find in cheaper kits. The 5/8-inch locating pin keeps each block indexed precisely on the axle pad, eliminating the lateral shift that causes premature u-bolt fatigue.

The blocks are finished in black and carry a standard replacement grade rating, so they slot in cleanly without modification. Superlift has been building suspension components since 1975, and that history shows in details like the pin spec and the iron construction — not in marketing copy.

Install time runs 1 to 3 hours depending on your setup and tools. This is a Prop 65 product, so California buyers should note the cancer and reproductive harm warning at P65Warnings.ca.gov. If you have questions about whether this block spec suits your build, our team is here to talk through it before you order.
