    Description

    Rear Lift Enhancement. The Tuff Country 4-inch rear block raises the rear suspension by 2.5 inches, improving vehicle stance and load capacity. It is installed by placing the cast iron blocks between the factory leaf springs and rear axle, enhancing lift without compromising ride quality.

    Construction and Appearance. The lift blocks are made from heavy-duty cast iron for durability and strength, while the extended U-bolts are zinc-plated to resist corrosion. The blocks are tapered to reduce driveline vibrations, ensuring a smoother ride.

    Installation. Installation is straightforward with a bolt-on design requiring no drilling. Factory length shocks may need replacement with extended shocks when installing rear blocks 2 inches or taller.

    Application. Designed specifically to fit the 1999-2005 4WD Chevy/GMC Sierra 1500 models for rear axle lift only. Not intended for front axle use.
