Re: Mack M75SX
The Emaxx tranny is a beautiful thing. I use them for most of my trucks. Are you gonna keep the 2 speed or make it a single speed? There used to be a conversion kit that almost cut it in half and basically locked it in 1 gear. I think you can still get an aluminum tranny case for it as well. Make sure you don't over tighten the tranny mounting screws, they strip out easily.
