        2 Top Rated Questions

        Will this bolt work with the 15-17 S550 Coyote Motors?

        • S550 Coyote motors have different internals than those from 2011-2014 Coyote motors. The internals in the S550s are forged and stronger as they are based off of the 2012-2013 Boss engines. With that being said, unfortunately this will not work.

        Is this a one time use only or can it be reused?

        • We would advise to not reuse this once installed and in operation.

            Great bolt

            The quality of the bolt and super thick washer and being 12 point. Looks awesome. It looks great with a ati super damper.. would deff suggest getting this as the factory bolt isnt as strong as this one either.
