Coil Spring IFS & Parabolic Leaf Spring Rear Chassis
We are proud to offer 1955-1959 Chevy Truck Coil Spring Chassis. 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. We offer chassis for cruising, autocrossing, drag racing, or fully polished show-stoppers, and anything in between. We offer a wide variety of options that allow you to custom tailor a chassis to meet your specific needs.
This Coil Spring IFS is engineered for enhanced drivability and a broader range of alignment adjustments. We have re-engineered the original spring towers to now utilize a vertical metal plate for mounting the upper control arms. This new design allows easy camber & caster adjustments via shims instead of alignment slots. This design eliminates the T-bolt design that was prone to slipping and throwing your alignment out when you hit pot holes.
These American-made Parabolic leaf springs are a modern implementation of traditional parabolic leaf springs. This design is characterized by fewer leafs whose thickness varies from center to ends following a parabolic curve. In this design, inter-leaf friction is unwanted, and therefore there is only contact between the springs at the ends and at the center where the axle is connected. The primary benefit of parabolic springs is better ride quality and not being as “stiff” as conventional “multi-leaf springs”. As an added bonus there are less springs which offers 28% weight savings over the 5 leaf kit previously offered. Only American-made steel is used to manufacture this TCI Engineering 1955-1959 Chevy Truck Coil Spring Chassis.
