Better engine builders know that cam lobe and lifter wear is 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 all new "CoolFace" lifter option is a must for these applications. Features 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. Crower has a complete inventory of . 842" and . 874" diameter lifters to choose from, including piddle valve, edge orifice, small chamfer, no chamfer and lightweight designs.
