13014KN BOX 2 OF 2

The Tuff Country 13014KN1-2 is a 3" front / 2" rear suspension lift kit designed for 2020-2024 Chevrolet Silverado 2500HD/3500 and GMC Sierra 2500HD/3500 (2WD/4WD) models. It's a bolt-on kit, made in the USA, and backed by a limited lifetime warranty. The kit includes powder-coated blocks and heavy-duty tubular upper control arms, engineered to maintain factory geometry and accommodate up to 35" tires. Shocks are not included, allowing for reuse of factory shocks or pairing with aftermarket options. Installation is straightforward with no cutting or welding required, with an average install time of 4-10 hours. For wider tires on stock wheels, a backspacing of 5" or less is recommended to prevent interference with the upper control arm.
