63-72 C10 Air Ride Rear "Notch Kit" with Watt's Link

63-72 C10 Air Ride Rear "Notch Kit" with Watt's Link - #120-5600-RW

This rear suspension kit is designed for 1963-1972 Chevy & GMC C10 trucks and replaces the factory rear suspension with a modern air ride, 4-link system featuring a billet Watt’s Link. The system is engineered to improve ride quality, handling, and axle control while allowing the truck to lay frame. Frame rails are NOT included.

All components are designed and manufactured in-house at our facility in Chandler, Arizona. Parts are laser cut using Amada equipment and formed on CNC press brakes to ensure consistent fitment, strength, and repeatable results from fabrication through installation.
