About this kit

Rough Country 97640 is a 3.5-inch knuckle lift kit for 2011-2019 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD models. The kit pairs machined steering knuckles with forged upper control arms and two M1 monotube shock pairs. It is built for trucks with rear overload springs and does not fit dually models or trucks with Magnetic Ride Control.
This 3.5-inch lift kit for the 2011-2019 Silverado and Sierra 2500 HD/3500 HD covers WT through High Country and Denali trims in both 4WD and RWD, as listed in the fitment section. Contents include forged upper control arms with OEM-style bushings, driver and passenger knuckles, torsion bar keys, and two M1 monotube shock pairs. It bolts on without cutting, drilling, or welding, and a torsion bar removal tool (1067) makes the front work easier. Confirm your truck is not a dually and does not carry Magnetic Ride Control before ordering.
