What's the difference between 1 ton and 1 1/4 ton Dana 60?

The D60 I got is a 1 1/4 ton part and I'm getting ready to put it and my 14b in and I was wondering if there was any difference between the 1 ton parts and 1 1/4 ton besides the 35/35 (rather than 35/31) splines on the D60.

there is no diff, AFIK. Just the military making it sound better for the CUCV's

There is no difference between a 1 ton or a 1-1/4 ton. Your axle has 30 spline stub shafts just like any other factory GM D60 front axle. The reason for the 1-1/4 ton is because the military simply rates a truck by the actual payload it can carry not by the std 1/2, 3/4, 1 ton ratings used in the civilian world which don't mean anything.

Ah, I see. Thanks for the info.
