The KPMI Racing Valve Spring Kit is engineered for high-performance boosted racing applications. KPMI valve springs are wound from Premium Kobe Super-Clean Chrome Silicon Wire and are heat-treated, stress relieved, and shot peened to support performance and service life.
KPMI engineers each spring for its specific application using proprietary spring design simulation and analysis software. The design process considers cam and spring harmonics, stress, mass, and operating RPM to help deliver the required spring performance.
This kit provides 80 pounds of seat pressure and 205 pounds at 0.435 inches of lift maximum. It includes lightweight heat-treated steel retainers and beehive springs designed to reduce reciprocating mass while providing the spring forces required for demanding racing use. The spring kit is designed for compatibility with the OEM integrated seal/base, OE number 3610212, where applicable.
