Lockers...air vs electric

I'm curious what are the pro's and con's of the electric lockers and air lockers? I know the pro's of having a selectable locker, but why the hassel of having to route air lines and mounting compressors when it seems it would be much easier just to have a electric locker? Thanks in advance

It's really just a personal prefferance issue. IMHO it seems that the air units would be a tad stronger and likely last longer. I went with ECTEDs for the LSD action when off, and will openly accept the need to replace clutches eventually. If it weren't for wanting the LSDs I would have gone ARB.

Be very careful with the wife mod. Uninstallation can be extremely expensive. Wife mods have been known to take the Jeep and all other mods during the uninstall process. Also, make sure you service your wife mod properly as often as humanly possible. Wife mods not properly serviced may malfunction or uninstall themselves at any time.

From what I have read the clutch locker are not as strong as a regular locker is, the electrics are on the new JK are being mad with mounts for a TJ now, The problem is there are really any great electrics right now like there are for the air like ARB, it's really a preference thing.

the Eaton E locker gets really good reviews, and running a compressor and air lines is not a difficult thing to do, no more difficult then running wires for an electric locker

Its mostly preferance.

I prefer electric because its what I am familiar with.

Electric is very easy to install. No compressor is needed which makes it cheaper and its one less part to fail.

Eaton makes a nice E-Locker.

You could also consider OX lockers. They just have a cable that manually locks and unlocks.
Just a thought.

A good friend of mine runs Auburn's ECTED at both ends of his rig. I can only compare them to my factory Rubicon air lockers. I like the fact that when you hit the button, there is an immediate action within the locker. When you need the locker it's there instantly. However, disengaging can be a pain in the ***. Unlocking usually requires serpentining on a high traction surface. Really annoying, especially with the front.

as someone who has owned both auburn ecteds and eaton elockers i can tell you there is no comparison. auburn ecteds are slow to lock up, slow and noisy to unlock, slip when you have reasonable traction, break easily (4 in 18 months), the limited slip is so mild it might as well be open, and auburn's customer service is horrible. eaton elockers lock immediately, unlock silently, and i have had no issues yet with breakage. yes, you might save a few hundred per axle with auburn ecteds but you will pay for it with replacement parts in no time. you've been warned!

I went with the ARB route. it's more expensive but it's rare to hear anyone having a problem.

I wouldn't say it's rare, but I would say that the ratio of failure to the amount of people that have them is pretty good. I went to the Molina Ghost run this past weekend and I know of 2 different ARB failures.

I really believe that electric actuation is superior but not many electric lockers can meet ARB's strength or quality.

Ecteds are junk. ANYTHING but Ected. They don't really lock as they just add addional clutch pack pressure that can be overcome with good traction. The axle engagement is a joke (9/16" WTF!) in the unlocked mode and is prone to stripping axle shafts. Good idea- very poor execution.

Eaton ELockers can be anywhere from great to shaky depending on the model. The new Dana 30 and 35 models are great units that my customers have loved. These units are 3 or 4 pinion designs are will outlast the ring gear. They have a collar style engagement that works very well and has proved durable. The Dana 44 model also uses the collar style actuation but has a 2 pinion design. It works very well but is weaker than 4 pinion competitors like ARB or OX. The 8.8 ELocker uses a pin style engagement that is prone to rouding pin ends. It is also a 2 pinion design. Eaton is working on a new design for 44 and larger models that should cure all the strength issues.

OX Locker now offers an electric version of their locker. Unfortunately is still uses a cable and uses a GM axle actuator to push and pull the cable.

The new JK Lockers (4 pinion) have been getting good reviews but can't be retrofitted to standard 44 cases.

For Dana 30 and 35 models I recommend ELockers but for nearly every other application I recommend ARB.

First question:the rubicon locker is also limited slip when unlocked and electrical.Is it worth it?
Second question:The ELocker for the dana35 like this one http://www.quadratec.com/products/16100_1014.htm can it be found for less than that anywhere else?Does anyone have a dana35 ELocker with upgraded 27spline axles?

1. The TJ Rubicon locker is air not electric, I believe the JK Rubicon is electric but will not fit in a TJ Dana 44.

2. There is always someplace cheaper then Quadratic and the one you show is the 30 spline version. try Google.

The part # for the 27 spline D35 Eaton ELocker is 19821-010.
