Comp Cams 812-16 Lifter Set

Comp Cams #812-16 SB/BB-Chevy Set... High Energy™ Hydraulic Flat Tappet Lifters Comp Cams® 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 engines rpm range, 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. 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 response [CHECK valve. Don’t take the chance of voiding cam warranties and losing power by using other brands of lifters!
