I upgrades to higher gear ratio and spline count with a OX locker and these things no longer fit my configuration, I have rear JK 30 spline axles which will fit all years 07-current and come with its bearings. In great condition asking $250 if you are just interested in the axles.
I also have 3.73 ring and pinion with carriers and all its bearings,race, and spider gears as well in great condition, asking $250 OBO.
I am a bit more firm on the axles than the gear set being only the axles would make great trail spares if you still riding stock equipment while trailing. As for the gears i can flex the price for those who aren't upgrading gears but more for replacing chipped ring sets or spiders gears. WILL SHIP IF YOU NEED IT AT YOUR EXPENSE.
