55-59 Truck Air Ride Backhalf

55-59 Truck Air Ride Backhalf - #110-8100-BH-A

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

This air ride back half kit replaces the factory rear frame and suspension on 1955-1959 Chevy and GMC trucks. It is designed to pair with the GSI 1955-1959 front clip to create a complete, modern chassis capable of laying frame while maintaining proper suspension geometry and drivability.

The kit requires removal of the stock rear chassis section and uses an inboard parallel 4-link with a billet Watts Link to control axle movement and accommodate wide wheel fitment. Firestone F9000 sleeve-style air bags are mounted behind the axle for consistent suspension travel and ride control.
