Superlift 99-10 Chevy Silv/GMC Sierra 1500/2500 4WD 3in Block Kit

This 3-inch rear block kit from Superlift uses solid cast iron blocks to raise the rear of your 1999-2010 Chevrolet Silverado or GMC Sierra 1500 or 2500 4WD. It's a straightforward way to level out your truck if you've already lifted the front, or if you just want a bit more clearance for larger tires.

The kit includes two cast iron blocks, which are a well-built choice for this application, along with the necessary U-bolts, nuts, and washers for installation. Cast iron offers good strength and durability for supporting the rear axle. This kit is designed to work with your existing leaf springs, making it a popular option for truck owners looking for a modest lift without a full suspension overhaul.

When installing, make sure to follow the manufacturer's instructions carefully, especially regarding proper torque specifications for the U-bolts to ensure safety and longevity. This kit is a solid option for many GM trucks from the late 90s through the 2000s, including models like the Silverado 1500, Sierra 2500, and Suburban 2500.
