Feuling Race Series full travel hydraulic lifters are machined from a steel body to handle the demands of large lift camshafts and high valve spring pressures. Engineered with a slower bleed down rate, these lifters maintain proper oil flow to the top end, enhancing valve-train stability and reducing valve float to promote maximum valve lift. Feuling recommends this series for engines operating with valve spring seat pressures exceeding 185 lbs, ensuring reliable performance in both street and strip applications.
Developed on the Spin-Tron dyno and track proven, these lifters are designed to increase engine RPM while maintaining consistent operation. For optimal performance and quieter operation, Feuling recommends pairing them with a high volume oil pump, specifically compatible with FEULING HP+ or Race Series models. Manufactured in the U.S.A., these lifters provide a robust solution for performance street and drag strip engines requiring superior hydraulic control.
