ARB air locker vs. Rubicon locker in my TJ

If you had a choice which one? Advantages and disadvantages? I am looking at the Rubicon 44 axle from jeepsareus, with the locker of course, then buying the Rubicon compressors, or a 44 with the ARB installed. I wanted the Eaton e-locker, but can't seem to find one. Any opinion is appreciated. Thanks again!!

Aren't the Rubi's fitted with ARB's from the factory?

Yes, but they require much lower air pressure to operate. Is this good or bad? Hence my question.

NO, they arent ARB's they are some air locker from somewhere like tokyo or something i forget, if your going to get a axle, just get the housing and put and ARB in it you'll be glad you did, i'm not to experienced and rubi lockers but ARBs have made a great name for themselves, plus if you buy just the axle housing you can add whatever you want like chromoly shafts and the gear of your choice jeepareus they come with the standard gear, 4:10's i believe. you can build your own axle alot cheaper then they sell a complete one for

Both have shown to be reliable. I run an ARB in my front axle and a MOPAR air locker in my rear.

If it's for the rear I like the mopar. It operates like an LSD when not engaged.

the Rubi 44 is a unique 44, it is like none other. it uses special gears and carrier. thus when using aftermarket parts in them, the install gets tricky. this is why you don't see a ton of rubi owners who have broken their lockers, switching to arbs. and there are quiet a few broken carriers in rubi's. (if you need proof, go to www.rubiconownersforum.com and then to the drivetrain section.)

i would fine a regular d44 from a TJ or something else to swap in and not use the rubi housing, but thats my opinion. do as you feel fit.

install on my rubi 44 housing was very easy, ARB's go right in, the rubi locker is just a hair bigger so had to use a tiny shim

There are very few broken carriers in Rubis. There was a cluster of them in Moab with people that ran the Nth Stinger that we're still trying to nail down. You can put an ARB in a Rubi axle if you want..a friend just built two bare Rubi housings up like that...but you'll find very few Rubi owners that will switch. We have no reason to. Our rear is a gear-based LSD when unlocked. Very nice. The lockers run at only 5psi so there are fewer hose and seal problems. They are also very strong.

They only require 5psi, unlike the ~100 for an ARB. The Rubi rear 44 carrier is a very well engineered and build product, most of the people who have broken them are either running much larger tires or have altered the housing. The fact that when it's open it acts as a helical gear LSD is something you aren't going to find many places.

I see no reason for a limited slip when you can be locked by pushing a button.

Personally, I would rather have a locker that is open when unlocked. An open diff is more predictable on slick roads.

How does that do in snow/ice? Personally, I prefer open/open on snow/ice. But why would you need LSD if you already have a locker? I suspose it'd be okay for wheelin' non-locked, but couldn't see any other value in having that if I already have a locker. I have ARB's, and yes...they require more pressure to lock, but it hasn't been a problem for me (yet) nor anyone else I know who run them.

It's a helical gear LSD, that's like night and day compared to a clutch based LSD like the trash lock. You can't tell it's there on the highway.

Well, for situations where you might want to throw down a lot of wheel speed in mud and not want to lock anything up the LSD helps and you don't have to worry about putting as much stress on anything with the axle being locked.

On the highway, you couldn't even tell if a locker was there.

How does it do around corners on an icy or snowy road?

I realize helical gear limited slips are superior to a clutch based as far as durability is concerned, but they still have the same characteristics of a typical limited slip as far as slick roads are concerned.
