63-77 Fiberglass Rear Spring - 340lb Rate
Available in your choice of 315lb, 340lb or 355lb applications. 315lb are designed to emulate standard suspension equipped Corvettes, 340lb applications will be similar to heavy-duty suspension Corvettes and 355lb fiberglass rear springs will be designed for performance applications. Such as autocross events or customer's that desire much stiffer handling characteristics from their Corvette.
Note: 1963-1977 Corvette rear springs are designed to be used with the factory or replacement heavy duty rear end cover utilizing the 9/16" bolts to attach the spring to the differential. If your Corvette has a replacement GM differential rear cover with the 7/16" spring mount bolts - then order the fiberglass rear spring designed for the 1978-1979 Corvettes.
