Tuff Country 73-91 Chevy Blazer 1/2 Ton 4wd 5.5in Rear Block & U-Bolt Kit

If you're looking to give the rear of your classic Chevy or GMC truck or SUV a bit more height, this rear block and U-bolt kit from Tuff Country is a straightforward way to do it. It's designed to lift the rear end by 5.5 inches, giving you more clearance for larger tires or a custom stance. This kit works by inserting the cast iron lift blocks between your existing leaf springs and the rear axle.

This kit is a well-built and economical option for adding rear lift. It includes the necessary 5.5-inch lift blocks, which are made from solid cast iron for durability. You'll also get extended, zinc-plated U-bolts that are custom-fit for the specific applications this kit covers. The zinc plating helps resist corrosion, keeping the U-bolts looking good and functioning properly over time. This kit is specifically for the rear axle only.

This kit fits a range of popular GM trucks and SUVs from the 1970s through the early 1990s, including models like the 1973-1986 Chevrolet K5 Blazer and the 1979-1986 GMC K1500 Suburban. It's a practical way to achieve a lifted look without altering your factory suspension components significantly.
