Description

The SuperLift 3849 is a 4-inch rear lift block kit designed to elevate the rear of your Silverado 2500 HD. This kit increases ground clearance and allows for the fitment of larger tires. It is constructed from heavy-duty Class 30 Gray Iron blocks and includes low-alloy, high-strength steel U-bolts with necessary hardware.

The U-bolts feature an anti-corrosive finish, and the kit comes with phosphate-coated washers and aircraft-type nylon-inserted locking nuts. Installation is described as simple but requires mechanical skill.
