Engineered for high-performance boosted racing applications, the KPMI Racing Valve Spring Kit delivers precise valvetrain control with 80 lbs of seat pressure and up to 205 lbs of force at 0.435" lift. The kit features a lightweight, heat-treated steel retainer paired with a beehive spring design, a configuration that significantly reduces reciprocating mass while maintaining the necessary spring forces to support aggressive engine tuning.
Designed for seamless integration with existing hardware, this valve spring kit is compatible with the OEM integrated seal and base (OE 3610212) where applicable. By combining reduced moving mass with robust spring rates, the KPMI kit ensures reliable valve operation under the high-stress conditions typical of forced-induction motorsports setups.
