KPMI Racing Valve Spring Kit 80-80750 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.
Each spring design is developed for its specific application using advanced spring design simulation and analysis software. KPMI engineers account for cam and spring harmonics, stress, mass, and operating RPM to help deliver the required spring behavior under demanding conditions.
The kit provides 80 pounds of seat pressure and 205 pounds at 0.435-inch lift maximum. 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. Where applicable, the kit is designed for compatibility with the OEM integrated seal/base, OE number 3610212.
