Comp Cams Valve Springs
These Valve Springs are specifically designed for the LS1 Chevrolet cylinder head and can be used as stock replacements or in performance applications all the way up to 0.625" lift and at engine speeds to 7500 RPM. These 1.290" springs have a coil bind height of 1.085" and are engineered to fit stock heads with no machining, utilizing the stock valve seat and spring retainer. the unique beehive shape has less mass at the top of the spring, for a lighter spring and retainer. Its special design and ovate coil help keep the valve springs in control, allowing greater engine RPM and reduced spring rate while maintaining precise cam lobe profiles. Durability is unmatched, especially in higher lift applications.
Lunati LS1 valve springs are available in chrome silicon or the super duty Pro Mod. The chrome silicon valve springs are excellent for use in your street machine or Saturday night bracket car, while the PRO MOD valve springs were designed for serious racers.
