Crower 66291X903E-16 EnduraMax Mechanical Roller Lifters

Crower designed these 66291X903E-16 EnduraMax Mechanical Roller Lifters for 1966-90 Big Block Chevy 396-454 engines. They feature “Full Time” high pressure oiling (HIPPO) to the roller bearing assembly and the Needleless Bearing Option. This continuous oiling offers higher rpm as well as high spring pressure capabilities.

These Cutaway style roller lifters feature an alloy body, lightweight design and a blade that has been raised to fit taller lifter bore blocks.

New lifters must be used when installing a new camshaft to avoid premature lobe and lifter wear.
