1997 TJs came with a 3.55 and 3.54 ratio, front and rear. And the next time you find an axle on a TJ that says 4.11, go look at the other axle because it will say 4.10. Same with 3.73, the other axle will be 3.74.

Because of the different size ring gears on our front and rear axles, like D30/44 or D30/D35c, they will usually be .01 different from each other. This is because it's just too hard to machine the gears so the ratios are identical when the gears are different sizes.

The .01 ratio difference is a non-issue. Just turning slightly left or right means the front axle is rotating at a faster rpm than the rear axle than a .01 difference between the front and rear axle ratios would cause.

jamesbernatchez Local guy has an 8.8 w/ discs and 3.73 gears out of an Explorer for $150 that is setup for an XJ. So I figure I will at least need to remove all the brackets and weld on the TJ stuff. I am waiting to hear back from him.

mxracer513 Here's some that me and a buddy have. They're for sale but i'm not trying to sell them on this thread just stating some gear ratios that i've come across.

Ford 8.8 3L2 (LSD 3.73 i believe) From a Mustang

Ford 8.8 1993 Mustang 3.43 Gears

Ford 8.8 1991 Explorer 3.55 gears

Ford 8.8 2000 Mustang 3.27 gears

Ford 8.8 1993 Explorer 3.27 gears

Ford 8.8 1995 Explorer 3.55 gears (disc brakes)

Ford 8.8 1991 Explorer 3.55 gears

Ford 8.8 1993 Explorer L73 (LSD 3.73) gears

Got my brackets from mad4x4 great quality 3/16 stuff!
I agree. The I think flange yokes are much stronger and easier to work with if you have to do a trail repair.

Odd, that you all mention the 3.23 stuf etc....All of the 8.8's I've seen out here have either been 3.73 or 4.10.
05-05-2009 06:12 PM
Coyote_94YJ Your right. My question was meant to be rhetorical I guess. Or more of a statement.
05-05-2009 06:03 PM
pyro sure they do

you forgot 2.73 and 3.23, two of the most common stock 8.8 gear sets.

stock TJs would be close, but which one matches exactly? 3.73.
05-05-2009 03:02 PM
pyro yes it does

i didn't count the gear install, because unless you got lucky with the Explorer having the same gears (3.73 only), you'd be replacing the R&P anyway.

jamesbernatchez Local guy has an 8.8 with discs and 3.73 gears for $150 that he set up for an XJ with shock and spring mounts. I would have to grind it all down again and weld the new brackets to it but for $150 it sounds pretty good.
05-05-2009 02:48 PM
pyro Thank you M.O.T.O. Thus y i am asking about the 8.8s
05-05-2009 02:44 PM
booger easiest would be a D44 out of an LJ or TJ Rubi, but they're pricey and that's why so many people go the 8.8 route.
05-05-2009 02:42 PM
pyro is easiest a better word then best? Im gonna get into a project, so I want to do it once and not have to worry about it again till I do another sereous upgrade. Naa mean?
05-05-2009 02:35 PM
booger it depends on what kind of deal you can get and how much work you want to put into it.

i don't know that there's a "best" answer since there are several good ways to accomplish the same goal.
05-05-2009 02:22 PM
pyro Is the explorer the best 8.8 to use? Or should I keep an eye open for a rear out of another vehicle?

What about the front?

Yes you will have to weld on the brackets and stuff. It isn't a one for one swap but it doesn't take too much to do the swap. With the proper tools I would imagine it could be done in an afternoon.
05-05-2009 01:26 PM
Coyote_94YJ Oh, well free is a different story altogether.

The only thing left would be a setup kit for the ring and pinion. I can see how that could be close to the same cost as an exploder 8.8. In regards to the average joe installing a fox 8.8, I can see only one other drawback and that is paying someone to setup the ring and pinion. That is not something most people can or will do. Yes for some it will be unavoidable but there are enough toasted exploders floating around that one could (without too much trouble) find a rear end with the same gears they are currently running.

So I will partially concede. Provided your prices are average throughout the US its possible to build a fox 8.8 for about the cost of an exploder 8.8. BUT, it would require more labor and it's not something the average person would be able to do on their own.

booger the 8.8 itself is free... i've been into Mustangs for years so i have tons of parts laying around. however, going price in my area for one would be $100-$150.

i'd then hit the junkyard for two driver's side Ranger/Explorer axles and the 31 spline carrier. that would be roughly $100 total for axles, drums, and a carrier with Trak Lok.

personally i'd rather have my driveshaft stay straight instead of 2 inches to the passenger side. you'll replace less u joints in the long run...

and coyote, just because lots of people do it, it doesn't make it the best way.

i'd swap in a D44 if it wasn't cheaper in the long run for me to use a fox Mustang 8.8. i know it's not for everyone, but it works for me and you can't say i don't have solid reasons for why i picked what i did.

Your right. Just because lots of people do it doesn't make it the best way. My point with that statement was that with all these people swapping in the exploder 8.8, I've not seen or heard of one person complaining about u-joints being an issue. So it can't be that much of a problem.

I'm not disagreeing with you that a fox 8.8 would be a better cleaner setup, I just can't see the cost to benefit as being economical.

how much is it costing overall for the axle, new carrier, shafts, etc?

Coyote_94YJ Exactly and the cost of the 31 spline shafts and new carrier you'll need to upgrade it isn't worth it. You'd be better off money wise with an exploder rear end.
