Shelby Mike Racing has just developed Billet Timing Arms for the Ford Coyote Motor. The OEM arms are made from plastic. Timing of your engine is critical. I would feel much better knowing the arms holding my timing chains in place were made of billet rather than plastic. These new Arms use the OEM wear plastics. Simply unclip them from your plastic arms and clip them onto the billet arms. We are taking pre-orders now...Expected delivery will be mid to late June 2016!
