63-66 Chevy & GMC C10 Air Ride Backhalf

63-66 C10 Air Ride Backhalf - 120-5600-BH-A

**This product will have a lead time; please call to verify expected wait**

This air ride back half kit is designed for 1963-1966 Chevy & GMC C10 trucks and replaces the factory rear frame and suspension with a fully engineered 4-link air ride system. It allows the truck to lay frame while accommodating wider wheel and tire setups.

Constructed from ASTM A1011 hot-rolled steel, this system is built for consistent strength, excellent weld quality, and long-term durability—meeting or exceeding the strength of OEM components.

This back half is intended to be paired with our air ride front suspension kit to create a complete, properly balanced air ride chassis. When a front kit is installed on its own, the front of the truck is lowered while the rear remains at stock height until a back half is added. For optimal performance and ride quality, air ride components should be matched front and rear. While this back half may be compatible with other front systems, it is engineered to work seamlessly with our air ride front kit for the best overall results.
