What is the purpose of the tapered blocks?

The blocks are tapered to help correct the pinion angle of your driveshaft after lifting the rear of your truck. This adjustment is important for preventing driveline vibrations.

What does e-coating on the u-bolts do?

The e-coating is a protective finish applied to the u-bolts that helps them resist corrosion. This ensures they remain strong and functional, especially in harsh weather conditions.

What are the available lift heights for the blocks?

The suspension blocks in this kit are available in several heights, including 1.25, 2, 3.5, 4.5, and 5 inches, allowing you to choose the amount of rear lift you need.
