63-66 Chevy & GMC C10 Air Ride Chassis

63-66 C10 Air Ride Chassis - #CHASSIS6366-AIR

The GSI 63-66 C10 Air Ride Chassis is designed for builders who want their truck fully slammed, riding on modern suspension geometry. This chassis is meant to lay frame while delivering modern handling, increased structural strength, and a heavily refined ride quality. 

Hand-fabricated and fully welded by professional fabricators, each chassis is constructed using MIG and TIG welding and precision-manufactured components for uncompromising strength and consistency.

Designed to Lay Frame

This chassis was engineered using laser-scanned OEM frame data to support accurate vehicle-specific fitment and true frame-laying capability. Optimized suspension geometry is designed to minimize camber change and bump steer throughout suspension travel while maintaining stable alignment at ride height.

Integrated features such as GSI Lower Control Arm Alignment Cams and the GSI Tie Rod Adapter Kit make dialing in alignment simple while maintaining proper steering geometry, even when the truck is laid out.

The rear suspension and notch system support extreme lowering and accommodate wide wheel setups up to 24” x 15”, making this chassis ideal for high-end street trucks, show builds, and performance-focused rides.

A Serious Foundation

Primary chassis and suspension systems arrive installed, with select components and some optional add-ons shipped boxed separately on the pallet as needed. The foundation is now just about ready to accept a body, brakes, drivetrain, wheels, and hard lines with no guesswork.
