    Available single or dual, these valve springs are formed from chrome silicon wire & finished using a cutting-edge heat treatment. This advanced heat-set takes the load loss out of the springs during manufacturing (instead of their first use) to extend spring life and ease break-in. The springs offer excellent fatigue resistance & load loss characteristics ideally suited to oval track or drag racing.
