Tuff Country # 97030 block kit include lift blocks and ubolts designed to raise the rear of your Chevy Silverado 1500. Installation is done by inserting the cast lift blocks between the factory rear leaf springs and axle. Extended zinc plated rear ubolts designed specifically for the Chevy Silverado 1500 are use to replace the factory ubolts.
1. Designed for rear axles only. Never use lift blocks with a front axle
2. Included 4" blocks replace the factory 1.5" blocks
3. On most applications factory length shocks must be replaced with extended length shocks when installing rear blocks 2" in height or taller. Please see our "Shock Absorbers" section for applications.
