Crower 66263E-12 Features:

CNC-machined, heat-treated 1-piece body delivers maximum rigidity and wear resistance for Holden inline 6-cylinder valvetrain builds. EDM oiling feeds a precision hole from the oil band to the needle bearings for superior lubrication in high-load areas. Redesigned bearing slot adds more shrouding around the critical bearing area to help reduce tappet and lifter bore wear. Control-contoured tapered needle bearings support high-rpm and high spring pressure applications with exceptional load capacity.
