Barra 4.0L – Heavy Duty Atomic timing chain kit

Atomic timing chains for the DOHC Ford 6 cyl are more than 80% stronger than the stock chain and are highly recommended for use with heavier than standard valve springs. They are pre-stretched at the factory and feature rollerised trunnions with extra thick link plates to provide the utmost in reliability. Will fit standard or aftermarket sprockets and have OE style timing links for easy timing.

The best timing chain in the world is no good if the guides do not keep it in place, so we manufacture a heavy duty replacement for the failure-prone OE timing chain guide pivot.

CNC machined from 4140 chrome moly steel, Atomic guide pivots feature 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, Atomic pivots are inexpensive insurance against premature valvetrain failure due to erratic timing chain movement.
