I installed the MML on my install. I believe that you can get by without having to install it, but you have to do some trimming on your fan shroud and stand somewhat of a chance of throwing your driveline angles off and causing vibrations.
If you're installing the OME lift and BL, I would suggest installing the MML while you're at it. It really didn't take that long (maybe 30 minutes).
Good luck with your install, I'm still more than happy with this setup!
