Pickup 1500 1988-1998 Chevy 2.5" Lift Rear Block and U-Bolt Kit by Rough Country

The Rough Country 6521 Rear Lift Block and U-Bolt Kit is a simple and effective solution for restoring ride height or adding lift to the rear of your Chevy Pickup 1500. Whether you're correcting rear sag or leveling your truck, this kit delivers reliable performance with an easy installation.

This system includes a pair of 2.5" tapered lift blocks, designed to raise the rear while helping maintain proper driveline angles. Unlike standard cast blocks, these heavy-duty blocks offer improved strength and durability for long-term use.

Each block features a 9/16" center pin for a secure fit into the factory axle pad, ensuring proper alignment and stability. The included square-style U-bolts are constructed from high-strength steel and finished with a corrosion-resistant black e-coating for long-lasting protection.

With extended thread length for easy installation and a vehicle-specific design, this kit provides a straightforward upgrade for improving stance, load support, and overall appearance.
