KPMI Racing Valve Spring Kit 30-30720

KPMI® valve springs are wound from Premium Kobe Super-Clean Chrome Silicon Wire. KPMI® valve springs are heat-treated, stress relieved, and shot peened to insure maximum performance and life. Springs are engineered for each specific application using proprietary advanced spring design simulation, and analysis software. Engineers pay special attention to cam and spring harmonics, stress, mass, and operating rpm.

The KPMI Racing Valve Spring Kit is engineered for high-performance applications, including 2004 and 2005 Honda TRX450R models. Each spring is wound from Premium Kobe Super-Clean Chrome Silicon Wire and engineered using advanced spring design simulation and analysis software.

KPMI valve springs are heat-treated, stress-relieved, and shot-peened to support performance and service life. Engineering considerations include cam and spring harmonics, stress, mass, and operating RPM. The kit is designed for compatibility with the OEM integrated seal/base, OE# 3610212, where applicable.

The lightweight, heat-treated steel retainer and beehive spring help reduce reciprocating mass while providing the spring forces required by high-performance boosted racing applications. The KPMI Racing Valve Spring Kit is identified by SKU 191-21012 and part number 30-30720.
