Anyone know what GM axles are on the H3?

It looks like a 10-bolt (Dana 44 equivalent) in the rear and someone said the front has a 7.5" ring gear.

Anyone know the GM part numbers for the axles?

Rear is an 8.6 and front is a 7.5 (pretty damn sure on those sizes). As for manufacturer, they are American Axle. The locker is an Eaton Locker. Basically the same axles used in full size pickup trucks running V8 engines.

So it should be relatively easy to find a front locker, beefier axle shafts and > 4.88:1 gears for these then.

Any idea what the spline count is on the axles?

Not sure, haven't looked for any gears; satisfied with the 4:56, but then I'm not installing larger tires. No idea what the spline count is at this time. They should be pulling a rear axle in a few weeks in the center I work at, so if I can remember, I'll go count the spines.

I feel dumb after you guys chat.
