Total Cost Involved Engineering’s 1937-1939 Chevy Car leaf spring kit. These American-made Parabolic leaf springs are a modern implementation of traditional parabolic leaf springs. Enjoy a smoother ride with parabolic springs. These specialized components differ from conventional multi-leaf systems in how the thickness varies, following a parabolic curve. Their design eliminates inter-leaf friction and provides contact only at the ends where they attach to the axle. This innovative option offers superior road comfort as well as 28% weight savings compared to previous 5-leaf kits.

This 1937-1939 Chevy Car leaf spring kit includes everything you’ll need to install a brand new suspension into the rear of your vehicle. 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).
