Eliminate your Corvette's choppy ride, restore lost ride height and eliminate unearthly squeaks and moans, all by replacing your worn-out steel leaf spring with a fiberglass replacement. A fiberglass leaf spring will give you a smooth, comfortable ride and will do so without sacrificing performance. These are TRW design composite/fiberglass rear springs, which can be fitted on any Corvette from 1963-1967. They provide a very superior ride while maintaining the excellent handling associated withthe Corvette. These springs are state of the art and this technology was standard equipment on all 80-96 Corvettes. This upgrade is one you will be very pleased with! Our springs come with all the mounting hardware, including spring bolts and special heat shield. These springs are absolutely the best available and have been tested over millions of cycles on special test equipment.
