This 2" rear leveling lift kit for 2007–2024 Chevy Silverado 1500 and GMC Sierra 1500 uses fabricated steel rear lift blocks and extended U-bolts to help correct factory rake, add ground clearance, and create room for larger tires while maintaining a factory-like ride feel. Vehicles equipped with a 1" stock rear block will gain about 1" of additional rear lift when installing this 2" block kit. The heavy-duty carbon steel blocks feature a cross-gusset, single-pin design for stable axle location, are tapered to help correct pinion angle, and are finished with a textured black powder coat for added corrosion resistance. The extended U-bolts are zinc-plated, heat-treated SCM435 steel to provide strong, durable clamping force. Bolt-on installation includes instructions and requires no drilling or cutting; typical install time is about 2–3 hours with basic tools.
