Dually rims

What are the specs I need to have for a spare set of rims?? All I know is that it is an 8 lug metric pattern. I do not know the offset either.
I would like to buy a set of 17" or 18" rims for my 2000 F-350 Dually



Also, what rear diff do I have?? I'm wanting to get a posi unit.

Grab a flashlight and a wire brush. There's a tag on the dif that's hard to read. Scrub it down and post. I'll try to find the chart and get it to you.

Denny (btw, friend just switched to alloy and sold his set of six) Sorry

Assuming you have a 99-03 you have a D80.

Here’s a link with the specs, I put these on mine. https://rover.ebay.com/rover/0/0/0?m...2F252046283322

Here’s a link to the Truetrac I put in mine: https://rover.ebay.com/rover/0/0/0?m...2F300964506398

If you're looking to change the diff be aware that if you have 3.73 gears you actually need a 4.10 carrier as Ford used a slim 3.73 ring gear on a 4.10 carrier. Not all suppliers show this!

Not looking to regear, just add a posi unit to the back. If I am pulling a trailer I usually have to chain up to get up my driveway in the winter. When I "posi-ed" my F-250 Sterling 10.25", it helped a lot in the winter.

I'll check out the links and when it gets warm I'll pressure wash the diff off and look for a tag. It was 7* this morning.

What gear ratio do you have at the moment? If it's 3.73 then you need the 4.10 & up carrier. The Dana 80 is used in Dodge & GM trucks too but only Ford did this peculiarity.

‘If you’re not going to regear this is the part you need: https://www.justdifferentials.com/TT.../tt915a567.htm
Dont forget new ring gear bolts, probably rebuild kit too.

Here’s the same part on eBay but cheaper and taking offers: https://rover.ebay.com/rover/0/0/0?m...2F253915132238

I'm gonna need to work this into my budget. I'm guessing I'll have $1200 into it by the time I'm done.
What oil do I use?? 75w-90 or 80w-140??

I used the heaviest weight I could find 90w/140 IIRC. Yeah that’s about right, my gears, rebuild and install was $800, Truetrac was $250
