ARP Crank Bolt Kits Ford Focus, Fusion, Ranger / Mazda 3, 6, mx-5, Miata
The Duratec is an interference motor. Duratec crank pulleys and the toothed timing chain gear ARE NOT KEYED! If the crank bolt were to come loose, these items would spin freely - thus resulting in loss of cam timing an utter destruction of at very least all of your valves - worse - the pistons/cylinders, and or entire engine. Do NOT trust your motors life on anything less!!!
