About this kit
3-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 97740RED is a 3-inch lift kit for compatible 2020-2025 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks in 4WD or RWD. The box pairs red forged aluminum upper control arms with two M1 monotube shock pairs. It fits only trucks with a rear overload spring, and it does not fit dually, AT4X, or ZR2 models.
This 3-inch lift kit for the 2020-2025 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD ships as a no-shock lift box plus two M1 monotube shock pairs and a set of red forged upper control arms with ball joints already pressed in. Differential drop brackets keep axle angles closer to factory. The install bolts on with no cutting and can be returned to stock height later. Confirm your truck carries a rear overload spring first: dually trucks are out, as are AT4X and ZR2 models with their 1.5-inch factory lift and Multimatic DSSV dampers. A downloadable installation guide is available.
