Enhance the durability of your Ford Barra DOHC 6-cylinder engine with the Atomic Performance Chain Guide Pivot Bolt Upgrade. This heavy-duty pivot bolt is CNC machined from 4140 chrome moly steel, featuring larger fillet radii in the corners and a 33% larger locking nut (M8 instead of M6) for positive retention of the guide. Heat-treated to 55 HRC and black oxided for appearance, it provides a robust solution to the failure-prone OE timing chain guide pivot, ensuring optimal performance under demanding conditions.
