The Eaton ELocker is an electronically-selectable locking differential designed for drivers that need maximum traction on-demand. The ELocker works like this: while driving under normal conditions, it performs just like an open differential. However, that’s where the lone similarity ends. If an obstacle is encountered – a rocky trail, muddy ditch or other challenge – the driver has the ability to actuate the dash-mounted switch to activate 100% axle lock for maximum traction. The electromagnetic mechanism locks, capturing all of the engine’s torque and sends equal amounts of it to the drive wheels. A second flip of the switch deactivates the unit to resume normal driving. In addition, the ELocker’s internal gears are net-forged, providing the strength and durability necessary for off-road and recreational driving. Unlike traditional forging, net-forging allows for a more precise gear which improves performance and reliability. Moreover, the electronic control also provides added reliability over similar air-controlled products and a cleaner overall install. Only Eaton offers the broadest portfolio of differentials to meet the unique needs of performance and enthusiast drivers on the market today. Their lineup includes locking and limited-slip differentials, automatically engaging and driver selectable units as well. Choosing an Eaton Performance differential not only ensures ultimate performance, but their superior product quality reduces time spent in the garage and decreases wallet-draining driveline repairs.
This is in the rear D44 of my Jeep. Time will tell how durable it is. The new 4 pinion design appears to be pretty strong... if the magnetic locking assembly holds up, this should be a great locker.
One important thing to be aware of is that the locker should only be engaged while stopped or barely rolling. It also will disengage (unlock) briefly when shifting from forward to reverse or vise versa, so be careful on the gas when changing direction.

Do not buy
I bought one of these awhile ago it broke in two trips. It has pin that engage into slots and they take a real beating. If you are running a 8.8 do not buy this product you will not be happy.

Wow!!! Whose truck am I driving?
I have owned the same truck for 6 years now (2005 F350 4X4 Crew Cab Long Bed Powerstroke). Year after year in minus 20's in the snow and ice off road I have ALWAYS had to chain up. Embarrassing in your 4X4 while others with you continue on without having to do so. As well, what a pain in the !$$ in those conditions!
This year it was I who was doing some trail blazing! Yahoo!!! It was like I was driving someone elses truck! Wow!!! I'm tellin' ya man - BUY IT!!!
i have a 2000 toyta tundra 4x44.7 it says 3.909 axle ratio, then thought i read it had a 30 spline the heard 27? is there a way to find out? i was about to order this part? but hate for it to be wrong or is there one that fits and do i need a new diff cover for it to fit?

Thanks for the inquiry Phil88, the Performance Accessories 2 Inch Body Lift part # PER872 with this we would recommend maybe a 285/70/17 max.

I have a 2008 Jeep JK Rubicon with a 30 spline Dana 44 front axle. Will this fit my front axle, or is it only for non-Rubi 30 spline rear axles?

Your Rubicon takes metric bearings which won't fit this E-Locker. You would have to buy a Dana locker which we carry or switch over to a different unit. Ox locker, Auburn Ected, ARB Air Locker

Curious what I need for lockers on my 2012 JK Unlimited; running 2.5" on 35s; 3:73 gearing 6 speed manual. Front and rear & any special tooling? Is this something a novice could perform well (aka - good instructions, etc and approximate cost to complete (no labor cost)

The E-Lockers are pretty easy to install compared to other units like the ARB or Ected. Here are a couple of links for the units you would need for your JK.
I would install new carrier bearings while you are there. The front unit does take a different bearing to install also I have them listed in the links.
