I just looked at a 03 2500HD. the guy said it has the 4:10 gears in it. Is this the Eaton locking rear end? G80 I think its called?

yes it sure is. Just to make sure you can look in the glove box and you should see the g80 code.

yes, the infamous g80. known for blowing holes in gm diffs. you should be fine with the 14 bolt rear end on the 3/4 ton. most people that have trouble are those with 10 bolts (half ton rear end) and bigger, heavier tires.
