1963-1977 Rear Suspension Coil Over Conversion Kit with 350lb Spring Rate

This 1963-1977 Rear Suspension Coil Over Conversion Kit infuses late model performance into your vintage Corvette. This kit converts your Corvette to a truly independent suspension that is not possible with the mono leaf set up.

A true bolt-on design, this kit does not require any permanent modifications to your Corvette, so it can be returned to factory specs at any time. This race inspired rocker arm suspension includes life-long aluminum shocks that are completely rebuildable.

This suspension conversion kit offers adjustable ride height while on the vehicle and is lighter weight than the stock rear suspension. This kit comes complete with clear instructions and all necessary mounting hardware. Installs in approximately 3 hours with basic hand tools and no cutting, welding or drilling required.

  • Fits 1968-1977 C3 Corvettes
