Description

The Skyjacker BUK2789 Block and U-Bolt Kit is engineered to provide rear lift for a range of Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD models from 2011 to 2018. The kit includes specially designed ductile iron blocks, which feature fixed center pins and are tapered. This taper is crucial for correcting the pinion angle, thereby preventing potential driveline vibrations. The accompanying U-bolts are e-coated to ensure superior corrosion resistance, extending their lifespan and performance. These U-bolts come in various shapes and lengths to accommodate different applications. The blocks are available in several lift heights, including 1.25, 2, 3.5, 4.5, and 5 inches. This kit offers a direct solution for increasing rear ride height and improving suspension geometry on compatible heavy-duty trucks.
