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.
