Cognito 11-24 Chev Silv/Sierra 2500/3500 HD 2WD/4WD 1in Block and 16in U-bolt Kit (steel/straight)

Starting with 1-inch tall cast steel blocks, this kit from Cognito is built to add a bit of lift to the rear of your 2011-2024 Chevrolet Silverado or GMC Sierra 2500HD and 3500HD trucks, whether they're 2WD or 4WD. These blocks are finished in a semi-gloss black powdercoat, which helps protect the steel from corrosion and gives a clean look. The kit also includes heavy-duty, zinc-plated U-bolts that are straight in shape and measure 16 inches long, designed to securely fasten the blocks to your rear axle.

This setup is a straightforward way to achieve a 1-inch increase in rear ride height, which can be useful for leveling out a truck that has a slight rake or for accommodating slightly larger tires. The cast steel construction of the blocks means they are well-built and can handle the stresses of daily driving and towing. The zinc plating on the U-bolts offers good resistance to rust and wear, ensuring they hold up over time.
