What rear end?

[99redgtp]

My dad just bought a 2000 f350 dually crew cab auto 7.3 4x4. We were trying to figure out what rear end is in it and what ratio. It runs about the same rpm as my cummins at 70mph and I have 3.55s. The door sticker has a blank spot where the axel code should be. It will also turn all 4 rear tires so I'm thinking its a limited slip but without the code I'm not sure. Thanx guys.

More than likely 3.73 limited slip. Look at the rear diff cover. Should have a tag. It should say something like 373 LS or LS 373. I can't remember..

Generally SRW's were 3.73's running 70 mph @ 2K rpms, and Dually's run 4.10's...

PM me the vin and I will run an OASIS on it for you. It will show all the info, axel ratio, delivery date, and warrranty work done, etc. I do finance at a Ford dealership., and I will be happy to email the report back to you.

I have 3.73's and at 70mph I am right on 2,000rpm's.
