Tuff Country 06-23 GMC Sierra 1500 4wd 4in Rear Block & U-Bolt Kit

If you're looking to give your 2006-2024 4WD Chevrolet Silverado 1500 or GMC Sierra 1500 a little more rear-end height, this 4-inch lift block and U-bolt kit from Tuff Country is a straightforward option. These kits are designed to be installed between your truck's factory axle and leaf springs, effectively raising the rear of the vehicle by 4 inches. It's a popular way to level out the stance when you've added a lift to the front, or just to achieve a more aggressive look.

This kit includes cast iron lift blocks, which are a solid material for this application, and extended U-bolts that are zinc-plated to help resist corrosion. Tuff Country custom-fits these components to ensure they work correctly with your specific truck model. It's a well-built solution for adding rear lift without needing to replace your entire leaf spring setup.

This kit is specifically for the rear axle only. Make sure to check the fitment details to confirm it's compatible with your exact year and model. You'll want to have the right tools on hand for installation, as you'll be working with the suspension components.
