Originally I thought we were looking for selectable lockers for the 7.5.... ARB does not list one...
I searched the Detroit website and found NO listing for the 7.5".
http://detroitlocker.com/appspage.htm
but I later found a PDF that lists the part numbers you list.
Thanks for correcting me and sorry for the misinformation.

as far as selectables you are correct, there are none that I have been able to find, although personally i havent looked to hard as i like the lock-right. but the 7.5 does have plenty of parts available still. the 31-spline 8.8 however has the largest available aftermarket for it seeing as it was used in the rangers (slightly) all explorers, a ton of F-150s and 250, some of the broncos, and so on. but the 7.5 is a hearty little axle (it must be if it can put up with me...)

Yeah, I found about 10 or so on drivetrainspecialists.com or something like that, but none of them were selectable.

Maybe I'll save some dollar and swap in an 8.8" and put a ARB locker in it...lol...totally overkill...

the problem with the limited slip is unless you have the tools and know EXACTLY how to set-up gears you have to pay to have it installed by someone who does so you don't blow up your rear end in short order from having the improper contact path and backlash. the drop-in lockers are nice because all you do is pull the crosspin, the c-clips, yank out eh spiders and side gears, and add all the locker parts into it then throw the new hardend crosspin back in and its done.

Jason/TireIron: How's that lock-right of yours handle in this snow we've got now? Any unpredictability? Or does it handle pretty much exactly like it did w/ the open diff? You've got single channel rear ABS, right?

I was impressed (very impressed) at how well your truck waddled through those mud-puddles in Winchedon last year.. That is thanks to your choice of diff and tires no doubt.

the lock right is great, it got rid of all the unpredictability that the open rear had. I know exactly what it is going to do and when it is going to do it. with the open it would lose traction and go sideways when i least expected it, now i know that it's goig to go sideways and i know exactly how to pull it back to and how much gas medal will make it do different things in different conditions. driving with a locker is a matter of getting to know it, and once you know it it never changes, it behaves the same all the time every time. and if what people who drive the no-slip say is true than it would be even nicer as all the little quirks and pops that i dont even hear anymore from my lock-right won't even be there.

diff, tires, ground clearance, suspension choice, and ***** to the wall give her hell attitude. really a lot of it has to do with driver ability and how well they know their vehicle. I do roughly 50K miles a year in my boy so I know every little feeling and quirk that he has. I do still know my limitations though even if i like to ignore them. just wait till I get all my parts together hopefully this spring or summer, then I'll be really fun to watch out there...

IMO a LS is the best thing you can have unless you do hard core rock crawling or some kind of hardcore off-roading or drag racing...
Ben is right on this one: If you spend more time on pavement than on the trail, a limited slip is your best bet. It's a compromise between street-ability and trail capability.

And, if your Dad is opposed because of the money involved, look for a Trash-Loc from an 8.8 axle in a wrecked truck. Lower miles are better since the Ford limited slip differential (and most LS' on the market) use friction clutches. If you don't have any experience installing a differential, pay the money to have a drivetrain shop do the work. It will save you money down the road!

You'll save money over a selectable or a permanent locker, and have a good compromise between street manners and trail capability.

unless you know how to install gears the no-slip will be way cheaper as any1 that can change plugs and their own oil can install it... and it acts just the same.. i have NEVER heard ANY noise from it.. nor have i felt ANY quirkyness.. it acts just like its an open rear you just get traction when you punch the skinny pedal.. not a 1 wheel peel

The opinions I was referring to, was on what differential was "better".

I was not referring to the specific opinions on the full time Locker, or on a LS, or an Open.

Posting what the different types of diff's, and the advantages and drawback would have been nice...

Actually read the posts BEFORE my first post, hardly anybody knew what they were talking about while describing the functions of these rears...they just all agreed theirs was better.

MY OPINION is that I like my LS, and if I had the money, I would install a selectable air locker. Yeah, full time lockers are predictable, but so are thunderstorms...each useless to me on the highway...

Go Cheap Like We Did

Pull it into the shop and weld it! LOL! Dont seriously do it if this is your everyday driver. That was just a cheap way to achieve the locker effect, but only on our Off Road Only vehicles. I would never do it to my ranger, and never did it to my Scottsdale because the axles were built before I bought it with true 4wd when needed, plus I had 40"tires on half ton axles(built real well). But yeah, people used to do it to their rear ends on trail rigs and even their old camaros and whatnot. Full Time spin to both tires, but it also wears the tires Real Fast on pavement.

Hey also I have a question, how do I find out what I have on my 03 edge? Can I tell by the Vin?

take a look at the tag on the rear axle. it's bolted on with one of the diff cover bolts. it will tell you what axle and what teh gear ratio is and if it's factory L/S or not. the 7.5 and 8.8 are actually quite easy to tell the difference of if you have seen each before (the 8.8 is considerably larger) but the tag says right on it. it can be a little confusing at first trying to decipher the numbers on the tag, but if you have trouble feel free to post em up here, i've seen enough of the tags to not have any issues, also keep in mind that a number may be a little obscured behind the bolt head.

A good working limited slip is the biggest reason I bought the truck that I did. The Torsen LS worked great today in the 6+ inches of snow we got. As did the new BFG At's.

Have you noticed that most brands offer a locker of some form? Toyota, Mazda, Nissian, and yes....even Chevy offer an electric rear locker. About time I say. Give the people what they want. Today's high HP trucks need some kind of locker to put that power to the ground.

Since we are on the locker subject...just how good does a ford l/s work. I have an open diff. and want to get a ls or locker, I can get a ford one on ebay for cheap, so im just wondering how well they are.

You can read the 2-character axle code on the drivers door jamb label and decode it HERE.

If you are not sure if the axle has ever been changed, that same link tells how to read axle tags and gives methods for measuring the axle ratio and tests for limited slip or open.

Mine came with the 8.8 L/S. It's the Ford brand, or more likely, manufactured for Ford. Ford calls it the Trac-Loc. It's a clutch-type L/S, so those will eventually have to be replaced. On the street, the Trac-Loc works great; it's absolutely transparent. I can't comment much on its off-road capability since I don't get off road much. It would work well for most applications, but if you're hard-core off road, I'd definitely look at a the Powertrax No-Slip or a selectable locker.

With the 3.0, I'm not sure what your ring gear size is. If it's the 7.5, you won't find much (if anything) in the way of differentials. Lots of options though if you have the 8.8.

I have the 7.5, im looking for an 8.8 though so I can put some bigger tires on. I want 33's, but with the 7.5 it isn't happening.

why not run 33s on the 7.5? do you have 300HP? the 7.5 has the same 28-spline axleshafts as almost all ranger 8.8s (the shafts are interchangeable) and if you stick a locker in the 7.5 carrier you get rid of the spider and side gears where most breakage would occur and you get a hardened crossshaft as well. dont rule out the 7.5 just because "it's a 7.5" there are plenty of people running 33s and even 35s on 7.5s. the biggest reason for switching to an 8.8 would be the selection of aftermarket differentials, the 7.5 only has a full detroit locker, a lock-right, or a couple L/S available for it. hell if you put in a full detroit locker (replaces the entire carrier) and run the yukon 28-spline axle shafts you have eliminated any of the weak spots. the only real issue is when you start getting into real deep gears, like 4.56s and 5.13 when the pinion gear starts to get a little small.

you dont buy a locker for pavement anyway. its optimal design use is to go straight and in most off-roading situations in which you need a locker you are going straight.

i have a 7.5" full detroit locker and running 33s. i didnt switch to an 8.8 cause like tireiron stated the spider gears is where the 7.5 is the weakest, detroit locker=no spider gears.
