What Our Customers Have To Say!

Had a hot no start on my 6.0 powerstroke.  I recently had a different shop install a new motor and had nothing but issues. I got fed up with the incompetent mechanics from the other shop so brought it to hhh and repair.. they had a fast turn around and explained everything that was done incorrectly by the other guys. Hands down my best experience with a shop 🙌.. I will be returning for a Trans and some go fast parts in the near future.. thanks again Ben and Jeff!...IF YOU DRIVE A 6.0 POWERSTROKE THESE ARE YOUR GUYS
