We are proud to offer frames and complete chassis for the popular 1955-1959 Chevrolet pick-ups. The frame features main rails with an extended height from 6″ to 8″ for increased rigidity and clearance between upper and lower x-members while still retaining the original profile. The Custom IFS option is a no nonsense, no compromise performance front end based on our custom spindle. Geometry is designed to maximize cornering grip yet provide great street manners. This TCI Engineering Leaf Spring Rear Suspension assembly is engineered for Street and Straight Line Applications. Improve straight line traction and cornering performance while lowering the vehicle. We offer chassis for cruising, autocrossing, drag racing, and fully polished show-stoppers or anything in between.
