Would this crank fit a 2007 GT (4.6 DOHC)

  • Unfortunately, this Crankshaft is only designed for a 07-12 GT500. They have a different engine from your 07 GT. This Crank will not fit properly.

Will this crank fit a 5.4L DOHC Navigator engine? Looking to build motor similar to my Cobra R, since 00R parts are scarce.

  • This crank will be able to work the 5.4L DOHC Navigator engine. The only thing that you would need to use that is not mentioned is the GT500 damper bolt.

    Cobra jet crank

    Very nice product. Basically what you would expect from an oem manufacturer. Ready to go out of the box. We have another one in a 800rwhp car and it is living just fine with zero issues.
