Is a D30 a D30 a D30?

I found a good deal on a front locker for a TJ, and I want to know if it will work in my JK D30? From what I've heard, the JK axles are reverse rotation, but that shouldn't have anything to do with the lockers, right? Also, what about spline count/shaft diameter between the two models?

Thanks,
WRM

Looks like you need an RD100 for a JK Dana 30--27 spline, 3.73+ gears.

I'd verify with Phil (Trail Duty) or with whomever you are going to buy your gears and master install kits.

Nevermind; just heard back from PowerTrax and the lockright part number is the same for both the TJ D30 and the JK D30.

Has anyone used the Powertrax in their 2010 JK 44?

Looking for info on a powertrax locker for the 2010 non-rubi D44. I've heard folks are using other D44 lockers in place of with some mods but have no details. Anyone have any luck yet?

I don't know if it will work or not but I do know the jk d30 pinion shaft is larger than the old d30. I think something is different with the carrier to.

The JK 30 and 44 pinions are the same, bigger that TJ, YJ or CJ 30s. The carriers and carrier bearings are the same as old 30's you just need the right ratio case. I forgot which one you use

Those of you that think you know everything really annoy those of us that do!
