Summit Racing™ Valve Springs
Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential. Summit Racing™ springs are made from high quality steel with precision winding and surface treatments. Special consideration for reduced valvespring and retainer mass ensures stability at high rpm. This reduces valve float, extends the rpm range, and greatly reduces valvetrain wear.
