HIGH ENERGY™ HYDRAULIC LIFTERS
Patented orifice metering valve precisely meters oil to the rocker arms
Continuous contact between the metering valve and pushrod seat is maintained, eliminating excessive oiling at high engine speeds
Pushrod seat is made of a special powdered metal iron alloy that is heat-treated for strength and wear resistance
Contain a longer piston than conventional hydraulic lifters, which provides more load bearing surface and increases lifter longevity
Lightweight check valve disc allows for quicker response, which results in increased engine speed before valve float
Lightweight check valve disc maintains added control at all engine speeds and loads
