What? no sticky Ford specs?

I was half expecting to see a sticky that listed what cars came ith what gears. was just wondering if i could pick up a stock pumpkin from the bone yard with a bigger rear gear. i don't wanna go too wild and i figured that a stock deal would be cheaper than having my local tranny shop put a new one in.

It's also located on the door tag under AX



the Axle codes are

Conventional / Locking
8 -------------------- M 2.73
Y ---------------------Z 3.08
F ---------------------R 3.45
5 ---------------------E 3.27
6 ---------------------W 3.73

Some of these code's don't apply to certain years


mine in the picture above is E for 3.27 track-lock differential

bah....get 3.73's in a rebuilt track-lok. You'll be MUCH happier than with the 3.27s.

Why would you stop at 3.55's and not go up just one more notch to the 3.73's

Either way their both WAY better than the 3.27's. IMO going from 3.08 to 3.27 is a waste of time.

I kept the 3.27 Track-lok in my car only because it came with it.
It has a nice amount of pep and OK economy for a 5.0.
But If I originally had 3.08's or less I would have defiantly put in 3.73's

If I find a complete Track-lok unit with 3.55's or 3.73's cheep, I might just swap them out one day.

3.27's from 2.73's would make a noticeable difference in acceleration and still get fairly decent mileage.

Just don't forget to change the speedometer gear.

eh, i don't want any more hassle back there than yanking the axles, switching pumpkins, and putting axles back in. i'm gonna hav enough headaches everywhere else to worry about. so far, it doesn't even look like i'm gonna find a 3.27 trac- lok pumpkin.

Good point. I know where one is. I need to go get the gear. I already pulled the pumpkin.

actually, 3.31 is the steepest gear our cars got, found in the automatic 94/95SCs. Only problem is they all had traction control, so all the 3.31s were open rears, no TL.

I hope no one minds me butting in with these questions. They are closely related though and I never heard of 3.31s. I dont care about blowing away people on the track right now with my wimpy 8 and wimpy stock tranny/TC. do 3.27s TL give anything in the way of faster 60fts vs the open 3.08s? Can you use 3.73s and potentially use a TC that gives a decent balance of performance and economy. And is its smarter with your money to buy a complete Ford racing 3.73 pumpkin or get a used trac lok pumpkin and have it rebuilt with 3.73s. Is the price much different? Thanks and sorry to butt in again but its closely related. Im swinging toward 3.73s right now and need that extra push to make up my mind.

3.31s were not common, but they do exist. The only thing I know of that they came in was the 94/95 auto SCs. As far as the 3.73s and TC go, a higher stall converter will destroy your around town gas mileage, but as long as you keep the lockup, your highway mileage will be the same. 3.73s will hurt highway mpg a little, but not as much as you would think. 3.73s by themselves would actually probably increase around town mileage cause the engine wouldn't have to work as hard to get the same acceleration.
