Crower CoolFace Mechanical Flat Tappet Lifters

Good engine builders know that cam lobe and lifter wear is often caused by inadequate oil lubrication at the cam and lifter surface. With today's high rpm, high rocker ratio and high spring pressures, cam and lifter failure is at an all time high. Crower's CoolFace lifter option is a must for these applications. They feature a small diameter oil metering port (.024") that is precision machined in the face of the lifter. No significant oil pressure loss, but significantly improved cam and lifter longevity can be expected.
