The SuspensionMAXX SMX-152020 is a heavy-duty rear lift block and U-bolt kit engineered to add 2 inches of height to your vehicle's rear suspension. This kit is specifically designed for 4WD Chevy Silverado and GMC Sierra K2500 and K3500 trucks, and the K2500 Suburban model.

Ideal for those looking to increase ground clearance or accommodate larger wheels and tires, this lift block kit offers a straightforward solution. SuspensionMAXX products are noted for their precise fitment and consistent ride height adjustment, aiming to maintain a quality ride experience even after modification. Key specifications include a 2-inch rear lift height and a block lift type. The kit is designed for specific GM truck and SUV models from the 1988-2000 model years, often referred to as the 'Old Body' style, provided they feature 5/8 inch diameter U-bolts.
