LUNATI/HOLLEY 73925-16 Features:
Signature Series Valve Springs are manufactured using high-tech, super-clean chrome silicon alloy materials that are held to tighter stress relief and shot peen tolerances, making them stronger and more efficient than others on the market. A micro-peening process is used to increase durability and longevity of the spring, which means you can push harder for longer. In addition, the added heat treatment reduces load loss during operation. Some springs in the series are also nitrided for racers who are looking to increase lift capacity and number of cycles over the life of a spring. The Signature Series Valve Springs are perfect for extreme stress applications such as professional drag and oval track racing.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.
