COMP Cams Valve Springs, Retainers 26082-12 Elite Race Triple Valve Springs from COMP Cams have an .800? to .900? maximum lift and outside diameter of 1.680?. Designed for use with roller cams, they are widely used in aggressive and endurance applications such as Competition Eliminator, Super Gas, Super Stock and other Fast Bracket Classes, as well as boat drag and tractor pull applications. The metallurgists at COMP Cams scrutinize every piece of metal utilized in the creation of Elite Race Valve Springs to make sure they are of unsurpassable quality because fissures within the metal of standard spring wire, caused by molecular contaminants, are the weakest link in valve spring construction. These fissures appear to be immense under the Scanning Electron Microscope but in fact, are just microns wide. Diminishing the occurrence of these fissures in our valve spring steel is the COMP Cams standard when selecting materials.
