what diff?

[camarokiller]

I know you guys are going to beat me, but I can get a straight answer. What diff does the truck in my Sig have? It's got 3.54 gears, and its open. I've searched online and I'm seeing people say its a 60, 70, or 80?? Did the srw trucks have more than one option? Sorry if its an obvious answer.

As long as the truck was always a 2500 diesel you have a 70 rear end in a auto.

It's always been a 2500 srw auto. Thanks for the help.

D70 will be 3.5" axle tubes.
D80 will be 4" axle tubes.
D60 was not an option as a 2nd gen diesel rear.

All 1-ton DRW, regardless of trans. type, have Dana 80s. 3/4- and 1-ton SRW with autos have Dana 70s and 3/4- and 1-ton SRW with manuals have Dana 80s. This should be true for '94-'02 trucks.

Make any corrects to my info if necessary.
