Comp Cams 812-8 High Energy Hydrualic Lifters - Set of 8

Not all hydraulic lifters are created equal! The use of High Energy Hydraulic Lifters give you advantages not found in other brands of lifters. Our lifters have a patented constant orifice metering valve that precisely meters oil to the Rocker arms. Continuous contact between the metering valve and the precisely coined bottom surface of the Pushrod seat is maintained throughout the engine's rpm range, therefore eliminating excessive oiling at high speeds. The Pushrod seat is made of a special powdered Metal iron alloy and heat-treated for strength and wear resistance.
