Differential Dummy!
[updated:LAST EDITED ON 11-Nov-02 AT 06:23 PM (EST)]I am the proud owner of an '86 F250 4x2. I want to convert to positraction, but I don't know what gears I have or even what size differential. I know it's not a 9" because it's not pumpkin shaped. I figure it's and 8.8 or so. I also know that the gears that are in there will let me pull a building in half if I want to, but I cant burn rubber to save my life. What do I have? what do I need? Where can I get it?Thanks.
I'd also like to point out that I have a c6 Auto trans. If that's any help! If you like, Email me at Camerog@okstate.edu.

I'm probably not the best resourse for information, but I'm almost possitive that putting posi. in a 4x4 is more than possible. It's recomended. At least two wheels are providing traction at all times! For both the front and back. If you can only get it for either the front OR the back, then I'd recomend the back. It allows for better milage and response while on the street.

Your rear axle is either a Ford/Sterling 10.25" or a Dana 60. http://www.drivetrain.com has pictures & info that will answer all your questions - just scroll down the L side to "Differential..." and then scroll down & pick the diff you want to look at. They show all available ratios and all available diffs for each axle.

Thanks for the info. But what ratio do I most likely have? Maybe a 4.10? It is a Dana 60, I found out. What ratio whould provide the best mileage as well as put rubber to the road. Oh, here's the kicker. Because I want to have my cake and eat it too... I still want to be able to pull a pretty good load. 9 man boats and such...
Hope I can get some help.:-staun

It's most likely a D60 Semi-Floater. And, most likely, you have 4.10 gears. Why not stick with these? You can put on larger tires with no problems. If you want to stay semi-stock, then 3.55's would be good.

Someone posted a list of axle ratio codes in another thread recently. Look on the bottom line of the sticker in your door jamb under AXLE.

Posi-traction is a GM term.
Ford's are :Traction Lock or Limited Slip.
The front axle ratio has to be very close to the rear axle ratio for it to work.
ie: Front 4.09:1 Rear 4.10:1
Front 3.54:1 Rear 3.55:1
We need to verify what you have EXACTLY.
If it's a Dana > It's Easy,
Pull off the back cover and count both the Ring & Pinion Gear >>>>>then do the math

So assuming that it is a Dana 60, which Chrysler used in their 1960's muscle cars, is it probably ok to go pull the gears out of an old Charger or Duster as a replacement for the current pull-power gears?
