AMC 6cyl. 199-258c.i. High Energy Hydraulic Lifter 822-12

These HydraulicLiftersare engineered to the most precise specifications. These lifter have a patented constand orfice metering valve that preciselt meters oil to the rocker arms. Continuous contact between the metering calce and the precisel 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 powedered metal iron alloy and heat treated for strength and wear resistance.

COMP Cams® High Energy™ Hydraulic Lifters are produced with a longer piston than conventional hydraulic lifters. The extra length is made possible from a counter-bored pushrod seat position. The longer piston is produced with through-hardened steel that provides more bearing surface and increased lifter longevity.

High Energy™ Lifters have a light weight check valve disc that allows for quicker response. This results in increases in engine speed before valve float. This check valve also maintains added control at all engine speeds and loads. increases in engine speed can be attributed to this quicker respone check valve.
