About this kit
3-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 23240 is a 3-inch lift kit for 1999–2007 Chevrolet Silverado 1500 and GMC Sierra 1500 two-wheel-drive trucks, including Classic and 1500 HD applications. The kit pairs lift knuckles and a rear block kit with two M1 Monotube shock pairs. It fits 6-lug wheel models only, and it does not fit 2004–2006 trucks built with torsion bar front suspension.
This 3-inch lift kit for the 1999–2007 Chevy Silverado 1500 and GMC Sierra 1500 2WD covers Base, LS, LT, SS, WT, SL, SLE, SLT and Hybrid trims listed in the fitment section, plus the 1999–2000 Chevrolet C1500. Front height comes from lift knuckles while a rear block kit sets the back of the truck, and M1 Monotube shocks handle damping at both ends. Confirm you have 6-lug wheels and check the torsion bar exclusion before ordering. The assembly bolts on without cutting or welding, and a downloadable Rough Country installation guide is available.
