Rear Suspension Enhancement. The Tuff Country 3in Rear Block is designed to lift the rear of the vehicle by 1.5 inches, providing improved stance and potential clearance. It replaces the factory-installed blocks between the rear leaf springs and axle, ensuring the vehicle’s rear is raised effectively. This lift improves load handling and maintains a level ride height, making it a valuable upgrade.

Construction and Appearance. This kit features heavy-duty cast iron lift blocks that are tapered to reduce driveline vibration for a smoother ride experience. The extended U-bolts are zinc plated for corrosion resistance, ensuring durability and longevity under harsh conditions. The overall design is tailored for easy and reliable installation while preserving OEM style and function.

Installation. The installation process is straightforward, involving a simple bolt-on procedure with no drilling required. This allows for a seamless upgrade, typically completed with standard hand tools and minimal mechanical skills.

Application. Specifically engineered to fit 99-05 4WD Sierra 1500 models, this kit replaces the factory 1.5" rear blocks to deliver a consistent lift and improved rear suspension performance without compromising vehicle integrity.
