Tuff Country 97024 4-Inch Rear Lift Block & U-Bolt Kit for Chevy/GMC 2500HD 4WD

The Tuff Country 97024 is a 4-inch rear lift block and u-bolt kit designed to raise the rear ride height of 2001–2009 Chevy Silverado and GMC Sierra 2500HD 4WD trucks. This kit offers an economical and straightforward solution for achieving a leveled or lifted stance by working directly with the factory rear leaf spring suspension system.

Installation involves inserting the cast lift blocks between the factory rear leaf springs and the rear axle, taking advantage of the existing suspension geometry without major modifications. Extended, zinc-plated rear u-bolts are included to replace the factory units and properly secure the axle at the new lifted height.

Key Features:

• 4-inch rear lift height for aggressive stance and improved ground clearance
• Cast lift blocks insert between the factory rear leaf springs and axle
• Includes extended, zinc-plated u-bolts custom-fit for the application
• Designed for rear axles only — never use lift blocks on a front axle
• Note: On most applications, factory-length shocks must be replaced with extended-length shocks when installing rear blocks 2 inches or taller

Tuff Country's 97024 block and u-bolt kit is a cost-effective way to add rear lift to your GM heavy-duty truck without the complexity of a full suspension overhaul.
