COOLFACE SOLID LIFTERS
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. Call Crower
for pricing and availability. Crower also
offers the “CoolFace” option on
competitor’s solid lifters as well. Send
your competing brand lifters in to
Crower for precision EDM machining.
