Elite Race Double Valve Springs from COMP Cams have a .750?+ maximum lift and outside diameter of 1.680?. Designed for use with roller cams and created with a new processing technique for longevity and reliability, they are widely used in Camping World Truck, Dirt Late Model and Sprint Car racing. 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.
