Locker Springs

Hyperco Locker Springs are designed for use in most popular Ford 9-inch based “Detroit Locker” rear differential assemblies. They are used in most popular forms of Circle Track racing. The cone-shaped Locker Spring is designed to run in a load range to allow the “locker-style” differential to operate properly.
