1" OEM-style cast-iron rear block kit for single-rear-wheel GM trucks.

OEM-style cast-iron rear blocks safely add 1" of rear lift and eliminate the danger of stacking blocks. Made from cast iron just like the factory blocks for maximum strength and reliability, and designed to work with a ReadyLift front leveling kit for a slight rake.
