Okey her is my plan. arb air locker for the rear aussi for the front and 4.88s or 5.13s. im going to probaly be running 35s soon. . . . .
Are air lockers worth the price? I like the idea of having on board air.....
any thoughts or advice would be great. i think im having a offroad shop do the work.

ether way with both sets of gears, the truck becomes less of a DD. So if that is the case I'd vote for 5.13" because it's a 3.0 and it also leaves room for larger tires if you change your mind in the furure. Stick with 4.56/4.88 if you plan on using the truck as a DD.

Great choice in the locker department

i still dont like 4.88s i almost wish i went with 5.13s, my gas mileage is already shot to **** so i may as well have gone with 5.13s lol

do they make an ARB for the 28 spline 8.8? i would also suggest tossing an explorer axle under the truck while they're doing the work, 1 its stronger 2 you get disk brakes..

the ARB will also save your tires a little bit. a ranger is probably almost too light to get a detroit to ratchet around turns. atleast thats the problem my friend is having on his yoda.

one more thing i would say to do with the ARB is bypass all the switches, wires, fuses and solinoids and plug the air line directly into an air tank.. just my preference though. less stuff to go wrong...

I agree with this. If I were to do it all over again I'd definitely go 5.13s instead of 4.88s.

Gonna have opinions on this one, but....

I had the Eaton Elocker, had no problems, loved it. There are some guys out there that have had problems with the 8.8 version, though I think they worked that out.

Auburn ECTED is not a true locker, in that it uses clutch packs not a solid locking mechanism. Not good b/c it's not really 100% locked, good in that it may just slip rather than break. Pick your poison.

Check out the OX locker, though I am not sure if it comes in a 28 spline 8.8. The first production had problems, but I hear that's been worked out. Problem was it was so tightly machinged, that it was a PITA to engage. Uses a cable instead of air or electric. Probably the route I would go if I ever need to replace the Jeep diffs. Plus you get a SOLID diff cover for it.

if you look at a tire size to gear ratio guide. theyll tell you that going 65 in 4th gear your RPMs would be at ______ with Gear ratio ______.
so if you have stock 28's with 4.10's and your rpms are at 3300. than you change to 35's with 4.56 or 4.88 and your rpms are still at 3300......explain to me how that would mess with gas milage? as well as the fact that larger diameter tires increases top speed, and the gear ratio pics up the slack of the larger tires. making it run as if it was stock again, but with bigger tires. (No Change in Milage) or with 4.88's (Minor change (about 3600 rpms.) youd see a minimal advantage in accel. and somewhat of a change in milage.)

Excluding of course the way you drive it after the pretties are installed. and read pattern/wideness.
All my Numbers are Purely for example purposes only. a good tire/ratio guide is Here .

But by reading the chart. theoreticly. im correct. tire change, gear change to accomodate. gas milage and accell. stays same. go higher. and you lose milage but gain accel. and ay higher than that. and you break stuff having fun lol.

lmao I was looking at that chart and like wtf are the middle numbers haha gottcha.
Thanx for the replies. Keep the ideas coming....
SO ive now decided on 5.13s. if that chart is right at 65 i will be at 3500 in fourth. In oregon the speedlimit isnt over 65 anywhere.

The ECTED is both a locker (a locking mechanism that functions through an electronically operated ball and ramp system) and a clutch driven LS. I've had one in my 8.8 28 spline for going on 4 years without any complaints.
Let me rephrase that...

The clutch packs are what "locks" the rear, not pins or something mechanical, like the Elocker, ARB, OX, etc. I beleive Auburn's literature states it's rated for max holding torque of 18k in-lbs. That's b/c of the clutch packs, not something mechanical like pins or splines.
The clutch packs limit it, even when new.
Even John says it slipped when locked when he added LS additive....
https://www.ranger-forums.com/forum2...ighlight=ected


What happens when they wear? Read down on John's post, might want to ask him what came of it...
https://www.ranger-forums.com/forum2...ighlight=ected
Replacement of the clutch packs I hear consists of sending it back to them, leaving you with no wheels.

I'm not saying the ECTED is garbage and does not suit some people's needs, just stating exactly what you are getting with it. It's not a hard core, big tire, rocks, locker....but then some people don't need that, and the LS when off is a very nice feature for some.

Broke mine on 32s with a No Slip in the snow a long time ago in Centralia. The pics and post may still be on here somewhere.
I'd do it for the disc brakes alone, plus stronger tube and shaft. I beleive all 96+ have discs, prior to that it's still just drums.

They do play a role in lock up, but do not lock the diff.
As far as replacement, if you break an ARB or a Detroit in a four year period, you own it. If you break or wear down the clutch packs in the Auburn unit, you can send it back (which I will be doing in the next 3 months).

Personally, I have seen ARB's fail more than once on the trail (air line break, locking mechs fail to engage b/c of water entering the diff due to detached/broken airlines). I've also seen what happens when Detroits fail (similar to when an ECTED, ARB or any other locking diff fails; ring and pinion, carrier bearings demo)
I've locked and unlocked my ECTED more than once in the water, without any issues. And as far as asking N3LEZ, I don't have to because I've had my unit longer than he has had his installed. As a matter of fact, I think I was probably the first guy on this board to install that unit in the rear of my ranger. I actually installed the unit before I came to this board.
There are number of draw backs, as you have pointed out, but there also are several advantages.
From the link you posted....
This side gear moves laterally, placing pressure on the center block that places pressure on the other side gear. All this compresses the clutch pack and locks the two side gears together, resulting in a full spool instead of a differential.

I'm still trying to see where something solid locks the two sides. Not trying to be an ***, I just want to see where anything other than the clutch packs under charge cause this to be a "locker".

Also, I know plenty of people who have had ARBs and such that have not had to send them back after 4 years. You stated that you had no problems in the first post, yet in the second you are sending it back. Why?

I think we are beating a dead horse again, just trying to tell people what to expect....

E-locker is the way to go. Comparable price to the ECTED, but doesn't have any clutch packs to wear out. Doesn't have to be sent back to be repaired for an additional $125 either.

Almost any of the lockers that are full carrier replacements are plenty strong. You're ring and pinion or axle shafts will let go before the lockers will. The E-locker and ARB are comparable in strength, they just function a bit differently. The ARB is air actuated (obviously) while the E-locker uses an electromagnet.

Do they make ox lockers anymore? I thought they had stopped making them? I like the idea of ox lockers... less stuff to break! Unfortunately, I think you've got to get out of the vehicle to engage them, which, if you're lazy like me, is a disadvantage ove an elocker, ected, or ARB. I just think ARBs are waaaaaaaaay too damn expensive when you toss in the money for the compressor and everything else.

Im with Gearhead ARB are over priced whrn you throw in air compressor and line the only way it would be worth it to me is if you set up for on board air with a good tank and also are running Air bag over load or leveling assists as you could use it then to .

I like the Eaton there just as strong for less in the long run .
I like the OX locker even more as it is cable acuated nothing to go wrong , and lets just asume by some freak accident you snap an Aircraft cable (not guna happen ) you can still engage it via pulling on it where its broke , and you can mount the shifter anywhere in the cab and when it gets rough pull back and your locked ...
the Ox will run you about 100 more than the arb locker but you save the 300 or so it costs for compresser and valve kit for Arb ...

They stopped a while back, did a little redesign, now they are back. Don't have to get out, it uses different length cables to reach your cab.
