I think the ring gear diameter is too small...

Good info Joe. I didn't even know they made a kit for that purpose.

There was some blurb on the article in the link...

Fact: This axle received a larger ring gear, which improved its overall strength and addressed the premature failure issues of the 10.25-inch axles when used with 4.10:1 or numerically higher gear ratios. Unfortunately, it was designed with a smaller pinion bearing than its predecessor.

Is there any truth to that statement? If so, would the 10.25 kit have an upgraded pinion bearing?
