Selecting the correct valve springs for your application is critical to both performance and reliability. Preventing spring bind and valve “float” requires careful matching of all components. Beehive springs reduce spring and retainer weight, Nitrite treatment increases surface strength, and heat treating helps resist load loss. We offer springs manufactured by Comp Cams, Ferrea, Isky and PSI, the most trusted names in the industry. Spring pressures listed are rated at both “seat” height (S) and “open” height (O). These are just a few of our listings - please confer with our engine staff for further information.
