1973 to 1991 C30 Dually Chassis

MODERNIZE THE WAY YOUR CLASSIC TRUCK HANDLES WITH SUPERIOR STRENGTH AND RIDE QUALITY.
HAND FABRICATED, FULLY WELDED CHASSIS.

GSI's C30 Dually Air Ride Chassis is engineered with optimized suspension geometry to minimize camber movement throughout the suspension travel & eliminate bump steer. Our lower control arm alignment cams allow for quick & easy suspension alignment. Our tie rod adapter kit works with the suspension to eliminate bump steer and make adjustment easy. The rear is designed to accommodate most dually wheel set ups.

The GSI '73-91 C30 Dually Chassis has been designed and developed using the latest technology available in manufacturing. Laser scanning a factory chassis is the best way to achieve proper fitment of all aftermarket chassis components. Our chassis is MIG and TIG welded by professional fabricators. We use the highest quality Amada CNC Laser and CNC press brake machines ensure all parts will fit together at the welding bench and during installation. We also combine a full in house CNC Machine shop to enable us to manufacture every piece to our strict quality standards. Chassis come fully welded, pre-assembled to qualify fitment, then prepared for shipping.
