Which set of gears would be stronger. 4.56 with 9 pinion teeth and 41 ring gear or 4.57 7 pinion teeth and 34 ring gear. Would the later be thicker teeth?
4.56, much like axle shaft splines, more teeth is always stronger. Here is the proof from the experts.

Well, the axle splines are a set dimension so more splines equals a larger diameter axle shaft. An 18 coarse spline hemi input is stronger than the 23 spline fine input because the 23 spline input is 1 inch and an 18 spline is 1-3/16.
