Air Spring Kit | 7 Inch Lift Kit | Chevy/gmc 2500hd/3500hd (20-26)

Built for Chevy and GMC 2500HD/3500HD owners who tow and haul heavy loads, this Rough Country air spring kit levels your truck under load for safer, more controlled towing and hauling. It provides up to 5,000 lbs of load support to reduce sway and bottoming out when braking and steering — keeping your trailer level and reducing tongue weight.

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