The SuspensionMAXX MAXXStak Rear 1" Coil Spacer (SMX-15100) is engineered to provide a 1-inch lift to the rear suspension of compatible GM 1/2 ton SUVs. This spacer is an ideal solution for leveling your vehicle, creating clearance for tires up to 33 inches in diameter, or simply increasing ground clearance for a more aggressive appearance. Constructed from CNC-milled billet aluminum, these spacers are built for strength and longevity, ensuring they will not crack, sag, or rust over time. The design retains the original equipment shocks and coil spring insulators, which helps to maintain the comfortable stock ride quality and reduces overall expense compared to more complex lift kits. Installation is straightforward, requiring no cutting or drilling, and is completely reversible. The process typically takes about one hour with appropriate tools. This MAXXStak spacer is proudly 100% Made in America and is backed by the MAXX Structural Lifetime Warranty, reflecting SuspensionMAXX's commitment to quality and customer support. **Applications:** * 2002-2019 Cadillac Escalade STD and EXT (4x4 / 2wd / AWD) * 2001-2013 Chevrolet Avalanche (4x4 / 2wd / AWD) * 2001-2019 Chevrolet Suburban (4x4 / 2wd / AWD) * 2001-2019 Chevrolet Tahoe STD and Z71 (4x4 / 2wd / AWD) * 2002-2009 Chevrolet Trailblazer STD and XL (4x4 / 2wd / AWD) * 2002-2009 GMC Envoy STD and XL (4x4 / 2wd / AWD) * 2001-2019 GMC Yukon STD and XL (4x4 / 2wd / AWD) * 2003-2010 Hummer H2 (4x4)
