Hi all, currently my set up is a 2015 jku with 4.88 gears and a Dana 44 in the back. I want to get lockers for rear only right now but not sure which set up to go with. Air, electric? Detroit? E-locker?Trutrac? Ive been reading about each of them and the pros and cons for each but figured I would ask in her for feedback and which you all recommend.

Thanks

You're going to get 100 different opinions, and non will be "right".. The only 'right' one is what you decide..
I went with a rear-only Eaton e-locker.. I didn't want to get an ARB (air) actuated locker because I did not want the hassle of on-board air.. A year later, I ended up getting on-board air anyway though for airing up..
One advantage of electronically actuated vs air actuated is that wires rarely spring leaks and wires are easier/simpler to repair than high-pressure air hoses.

ARB's are nice. Dont let the whole air line thing scare you, they dont just break. In the off chance that they do, ARB sells a repair kit for like $25 that will have you back in business in 10 minutes.

Won't find a stronger locker than the ARB... But for most practical purposes, any of the lockers on the market are plenty strong.

The trutrac you mentioned in the OP is not a locker. It is limited slip. It is still an excellent device that has many advantages and may just be the most popular LSD for Jeeps but keep in mind that it is not a full locker. I recommend doing some reading on the differences and make a choice based on your area and the type of wheeling you do. After my son put trutracs in the front and rear of his TJ, I was impressed to the point that I most likely will put them in my JKU. We don't rock crawl and putting a wheel in the air is extremely rare for us so the low maintenance and automatic no fuss function is a huge plus for us. If you rock crawl and routinely have a wheel off the ground, a full locker ARB or Eaton e-locker might be a better choice. As far as air or electric, it depends on which you like better. I prefer the e-locker because I am familiar with working on electronics but I have seen guys use ARBs with no problems. All three are great options each with pros and cons. I don't recommend an auto locker like the Detroit locker on a daily driver if you have no experience with them. They have some on road handling quirks that are amplified on short wheelbase vehicles. I recommend finding someone locally that can you ask about their experience with one and maybe they can take you for a ride in order to decide if it is right for you.

DrDarren, there are pros and cons to both air and electric. On a 2015 JK you will want to stick to a selectable locker or it can interfere with the ESP system. The TrueTrac is a nice upgrade for a limited slip. Give me a call at 866-601-5340 and we can put together a great package for you.

If you have an auto trans (2012 up)you cannot put in a mechanical locker in the rear. Your choices are the selectable or truetrac LSD. Front is no problem since it is only engaged in 4wd which has different ESP parameters.

If you go ARB then you have to get OBA, might as well get a tank while you are at. Air your tires up, lock lockers, run (some) power tools.... its a win win!

And then there is the OX mechanical locker which can be actuated manually, or by air, or by electric.
