GMC Sierra Chevrolet Silverado 1500 2WD 4WD Steel Lift Blocks and Square U-Bolts Kit

Our GMC Sierra Chevrolet Silverado 1500 2WD 4WD steel lift blocks and square u-bolts kit is the safest and most affordable way to lift and level your vehicle rear without compromising OEM ride quality and changing the overall suspension or steering geometry. This lift kit includes 2 carbon steel lift blocks and 4 premium-grade steel u-bolts with grade 8 hardware needed for installation. With this kit, you can raise the rear between 2 3, increasing ground clearance to clear bigger tires or improving rear-end sagging when hauling or towing heavy loads.

Each component in this kit is specifically designed to work with one another, providing you desired lift height and maximum clamp force. U-bolt threads can be trimmed down if needed. Installation can be accomplished via DIY or professional installation and does not require special tools.
