About this kit

3-Inch Lift Kit with Vertex 2.5 Shocks, fitment-checked

Rough Country 97750RED pairs a 3-inch lift for 2020-2026 Silverado and Sierra 2500HD/3500HD with Vertex 2.5 reservoir shocks front and rear, plus red forged aluminum upper control arms. Rear overload spring required; dually, AT4X, and ZR2 trucks are not covered.

Damping is what sets this 3-inch lift kit for the 2020-2026 Chevy/GMC 2500HD and 3500HD apart: two Vertex 2.5 front units rated at 3.5 in and two Vertex 2.5 rear units spanning 3.5-7.5 in ship in the same package as the red forged upper control arms and the overload-spring kit box. Ball joints come pressed in, and differential drop brackets keep axle angles near factory. Nothing gets cut, and the setup reverses to stock height. Check for a rear overload spring and rule out dually, AT4X, and ZR2 trucks first.
