Racing Valve Spring Kit

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.
Features:

• 80 Lbs of Seat Pressure / 205 Lbs @ 0.435" Lift (Max)


• Spring kit is designed for compatibility with the OEM integrated Seal/Base (OE# 3610212) where applicable


• Lightweight heat treated Steel Retainer and Beehive Spring reduce reciprocating mass while providing the spring forces required by high performance boosted racing applications.
