Atomic Ford DOHC (Barra) Billet Crankshaft Sprocket - #306562

Billet steel crankshaft sprocket suit Ford DOHC 6 cyl engine. Suits 8mm (std) pitch timing chain.

On of the many products we developed for the Barra engine was an entirely new crankshaft sprocket. We learned quite early on that the factory crank sprocket was prone to premature wear (even Ford took to induction hardening the teeth from about 2005-on as a remedy to rapid wear).

Taking a different path from the factory style sintered type/low carbon material and made here in Sydney, Australia we went straight to a case-hardenable billet steel as the basis for our sprocket. From years of engine building experience we made a few design changes to the teeth and CNC programmed a “true roller” tooth form as opposed to a push tooth form for less friction and smoother drive. We also reprofiled the crank trigger teeth to provide a cleaner signal for the crank angle sensor, case hardened the teeth to HRC60 and black oxide treated the lot.

Laser etched with our brand and part number it is easy to identify a genuine Atomic crank sprocket from the cheap copycat items. Try not to be ripped off by buying a non-genuine product!
