COMP Cams® 26975 springs provide increased control and durability for GM crate circle track applications as well as a variety of Small Block Chevy/Small Block Ford engines. They are designed as a performance upgrade over stock springs for higher RPM applications. Made from a high-tensile strength chrome silicon steel, the #26975 Valve Springs feature a much higher life expectancy than tool steel springs. State-of-the-art grinding and finishing processes, along with added micro peening, also increase durability. In addition to street use, these springs are also a perfect choice for GM 604 crate engines running in stock or modified circle track divisions.
