The KPMI Racing Valve Spring Kit is engineered for high-performance boosted racing applications. KPMI manufactures these valve springs from Premium Kobe Super-Clean Chrome Silicon Wire, then heat-treats, stress-relieves, and shot-peens them to support performance and service life.
KPMI engineers each spring for its specific application using advanced 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.
The kit provides 80 pounds of seat pressure and 205 pounds at 0.435-inch maximum lift. Its lightweight, heat-treated steel retainer and beehive spring design help reduce reciprocating mass while providing the spring forces required for high-performance boosted racing applications. The KPMI spring kit is designed for compatibility with the OEM integrated seal/base, OE number 3610212, where applicable.
