Use with part # 305327 Springs
This new LS1 26918 Valve Spring s are specifically designed for the LS1 Chevrolet cylinder head and can be used in stock replacements with no machining all the way up to 0.0600" lift, and at engine speeds to 7500 RPM. 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 helps 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.
