Parabolic Leaf Spring Rear Suspension
Total Cost Involved Engineering’s 1949-1954 Chevy car leaf spring kit. 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 end 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 that offer 28% weight savings over the 5-leaf kit previously offered.
This 1949-1954 Chevy car leaf spring kit includes everything needed to install a brand-new suspension. Everything that attaches to the chassis bolts into place. There is minimal drilling involved and we reuse factory holes as often as possible to make the installation all the more easy. The only welding required will be on your axle housing (unless a complete Currie 9″ is purchased directly from us).
