The OBS dually rear is a Dana 80? I thought it was a 10.25 with longer studs or something....hmmmmm
That is a GREAT question...
My friend's 1997 had a dana 80. Found this out the hard way when a bearing failed. Autozone and Napa kept giving him sterling parts that didn't work. He bought the truck new, never had any other rear axle work done. I just spoke with JJ.. and his 1995 f350 DRW may have a 10.25, he will check.
Go jump under a f550. Looks like a damn dump truck axle.
Thats no sh!t looks like it should be a fockin two speed rearend.
I worked for a napa for several years, on superduties you could always ask if it had duals or single rear wheel to figure it out, but the obs trucks were hit and miss, some of the later trucks were dana 80's but some of the early ones were 10.25
