About this kit
3.5-Inch Lift Kit, fitment-checked
Rough Country 97630 is a 3.5-inch lift kit for compatible 2011-2019 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD trucks in 4WD or RWD. It is built around forged torsion bar keys, forged upper control arms, and matched driver- and passenger-side knuckles. It does not fit dually models or trucks with Magnetic Ride Control, and rear spring configuration must be confirmed against the fitment notes before ordering.
This 3.5-inch lift kit for the 2011-2019 Silverado and Sierra 2500/3500 HD bolts on without cutting, drilling, or welding, so factory components stay intact. The box holds the lift hardware with overload provision, forged upper control arms with OEM-style Clevite bushings, and precision knuckles that improve driveline angles and reduce CV bind. Front lift corrects factory rake and adds ground clearance. A torsion bar removal tool, part 1067, makes the job easier and is not part of this kit. A downloadable installation guide is available. Confirm dually, Magnetic Ride Control, and rear spring qualifiers in the fitment section first.
