Notorious EXB Diffs for Notorious…

[Craig A.]

Has anyone put Felony (rear) diffs in a Notorious?

 

[Engineer]

The Felony diffs aren’t EXB diffs and the Felony rear has a unique 3.07:1 ratio that is different that the 4.3:1 of the truck diffs (both EXB and non EXB). Probably not the best gearing for big MT tires either.

If the question is whether or not you could get it to physically fit, yes (along with swapping the input pinion).

I know it will fit, but my thought was more of “should I?”… you made me realize the additional torque I’d be putting on the diffs, which I didn’t consider when I posted. Noob move on my part. . Much appreciated!

NP - also forgot to add that the GP6 (Felony rear) are straight cut gears as well so theoretically not as strong as the GP4 spiral cut gears that are in the EXB diffs.

Ohh… good point.
