Ford 'N' case

Am wondering the biggest axles that can be put in this housing. Looking to step up to some 35 splines. Thanks!!!

You can purchase a spool that will fit any size case with a 35 spline. I would take into consideration how much power you will be making as the smaller bore cases, 2.890 and 3.062, will be good for maybe 850HP. Beyond that you should go with a 3.250 bore case with a 35 spline spool.

Thanks for the reply!!

I've got a Strange Pro N case in the smaller bore (3.062) with M/W 35 spline spool and axles. No troubles so far.

I've heard of some issues with other brand 35 spline setups in the smaller bores? Maybe that is outdated info now, this was a couple years ago when I built mine...
