Tuff Country 2-Inch Rear Lift Blocks (07-10 4WD Silverado 3500 HD)

Rear Suspension Lift. The Tuff Country 2-Inch Rear Lift Blocks kit is engineered to raise the rear of the vehicle by two inches, enhancing ground clearance and accommodating larger tires. It installs by positioning cast iron lift blocks between the factory rear leaf springs and axle, with extended zinc-plated u-bolts replacing the original hardware to secure the setup. This upgrade helps maintain factory ride quality while improving payload handling and stance.

Construction and Appearance. The lift blocks are made from heavy-duty cast iron for durability and strength, ensuring long-lasting performance under heavy loads. The extended u-bolts feature a zinc plating that resists corrosion and adds to the overall longevity, providing both function and reliability in demanding conditions.

Installation. Installation is straightforward with a bolt-on design requiring no drilling or permanent modifications, suitable for experienced DIYers or professional technicians. When lifting the rear by two inches or more, it is important to replace factory shock absorbers with extended-length shocks to maintain proper suspension travel and performance.

Application. This kit fits 2007 to 2010 4WD Chevy Silverado 3500 HD models and is intended for rear axle use only; it is not compatible with front axle lift applications.
