ARB or Truetrac for the Rear...
 

OK I am having one of those doubting myself days, in the coming month I am planning to do my front and rear axles...

For the front I already have an ARB to install (picked it up for $300 used), the compressor is already mounted, I'm considering sleeving the dana 30, upgrading the axle shafts, and the front should be good to go...

For the rear I'm really having a dilemma on choosing between an ARB and a Truetrac...

I like to way a Posi performs on wet, snow, or icy services....but since I already have an ARB front and the compressor run....will I regret going with a truetrac and not an ARB?

This XJ will be used for off-roading and exploring, it will see some snow and slick roads but also desert terrain and rocks...

What would be my pro's and con's with each?

I would go arb because you are set already. I run a welded rear and have no issues on slick roads.

I have an Aussie and can only speak for it, to me though if you have an arb for the front, might as well do one in the rear...

ARB, you already have a compressor. Do it.

The Direction this is going I may be spending an extra $500 for an ARB

I've been trying to talk myself in to the truetrac to save $ .....but there will be a day that I may wish I did spend the $..

There is something you Gotta love a 29" tired XJ ARB locked front and rear....

This is one of those things that "you get what you pay for". Consider maybe a Yukon Zip locker? same as ARB, but a bit cheaper. I think better warranty too.

I vote the arb also. You already have the compressor and you're already going to be paying to set the gears up.

Just think of how cool you'll sound telling people you got ARB's front and rear 8)

If you actually wheel it you'll hate a LSD. Lift a tire and it's about as useless as an open diff. Get a locker and leave the LSDs to the street rods.

So do they make a zip locker for the 8.25? What's your experience with it verse or Arb?

I don't think there is a Zip Locker for the 8.25.

For off-road I would go with a locker or selectable locker.

Spend the cash (save if you have too) and get the ARB. Mine has been extremely reliable and works exactly like it is supposed to. You already have the compressor and everything plus you get another cool switch haha. That is my opinion.

Did you upgrade to the braided stainless lines or stay with the plastic?

Go with the ARB, mine has been issue free. I have the plastic lines, been OK so far. If you have old air hose you can run the line in that for protection. I carry a repair coupling and spare line in case I do break a line.

I stayed with the plastic wrapped in convoluted tubing/routed high. This one has been in for about 5.5 years and its held up through all kinds of abuse. My last one (different Jeep) Lasted about 10 years and was still going when I sold it.

I did not know about the braided line... Might be worth it. Good routing will save it from most everything though.

While many, actually nearly everyone, is suggesting going with the ARB, consider this...

If you daily drive this, an LSD in the rear can be really beneficial for those unforeseen slick spots or black ice mixed in with dry pavement during you daily commute. There may be light rain that you don't want to do a full lock-up for, but the LSD would handle it well.

When you go off-road, you'll have the LSD and the ARB.

Just my opinion, but you know how that goes...

I'd go ARB in the rear, as stated in many other posts you've got the compressor. I've got a Yukon Zip in my D30 & an ARB in the 8.25. Great setup. On when you want them to be & off (open diff) when you don't.

Check out RWK Haus on here. I bought all my gears / lockers through Robert. Prices were great & service was great also. He's a vendor on here..

If you do a lot of street driving go with an arb, if its mostly off road you cant beat a Detroit for durability and a soild lock up every time, they can be a bit of a pain on the street if you see wet or icy conditions and lock up when when you don't want it to. just my .02

I guess I'm going with everyone else on here, the Detroit TruTrac isn't a locker, but it works well enough as long as the tires stay on the ground which isn't always the case when on serious trails. The ARB is a locker, and if installed properly with the air lines routed to protect them, it gives you the best of both worlds. Locked when needed and open when a locker isn't wanted.

Well....I pulled the trigger on a rear ARB and a 12ft stainless air
Line...so it will have front and rear selectable lockers.

What did the stainless line cost?

Thoughts on another idea?
 

I am in the same dilemma. I have an ARB up front already with the compressor of course. I also have the Country version so I have a TruTrak in the rear and it does not get the job done plain and simple.

I am thinking about an Eaton electric locker for the rear primarily due to having an alternative system should the compressor or lines loose pressure to the front locker. This way I should always have one of the two systems functioning.

Your thoughts and comments please.

Don't forget about OX, they are fantastic

If you have a C8.25 rearend you will have a hard time finding a E-Locker, nobody makes one. If you are wanting a selectable locker you are limited to a Air Locker.

You are wrong, look at OX its selectable it can be opperated by air or electric or mechanical lever or even a simple " drive away lock" if you don't want any of that. On top of it all as the last guy asked, he's afraid if one system fails he wants another. Here Ya go! Plus if even that fails you have a backup with the drive away lock. ARB can't do that...
I have an OX in my 8.25 with the electric actuator, it's awesome. Switch off, open axle. Flip the switch instant solid locker.

First time for everything :laughing:

I too vote for the ARB, I only have experience with Spartan Lockers. SHOOT besides ground clearance lockers are a great investment. My last outing i was keeping up with xjs with 33's and 4.5" open open. My little front and rear spartans got me through, just had to pick a different line with my ground clearance limit.

Side note not a fan of the harshness of my rear spartan on the street. Thats why I have an ARB for the rear when I lift. Already mounted in a housing with 4.56 gears.
