This is a High Performance Dual Valve Spring Kit from Kibblewhite. These Valve Spring Kits are required on engines using Stainless Valves, but are also highly recommended on any engine using a performance camshaft. These are the Valve Springs we recommend for most combinations, when using Camshafts with less than 0.380" of Valve Lift.
We offer a complete line of OEM and Aftermarket Parts, as well as a wide variety of services. Please Contact Us about any technical or other inquires.
