7 Inch Lift Kit | Torsion Drop | Vertex | Chevy/gmc 2500hd/3500hd (20-26)

Built for Chevy and GMC 2500HD/3500HD owners who demand serious ground clearance without sacrificing ride quality. This 7-inch lift kit uses a torsion drop design to preserve factory geometry—your axles stay in their original position and angle, and the stock track width is maintained for optimal handling. You'll clear 37" to 40" tires while keeping that smooth, comfortable ride you expect from a premium truck.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.
