Would someone be kind and make me a parts list to change out my stock 3.21 gears on my 2012 jku sport. I would like to go to 4.56 and lockers front and rear. Would like cable lockers but air would be fine.

You'll need a new carrier up front as well I believe.

Ok well as jwink41 said than you will need new carrier for the front axle. There not spendy.but when it's apart you might look into eaton trutracs good up grade if your going to leave diff's open . There around 500.00 give or take a few dollars.

without the locker, you'll need a new carrier because your currently running 3.21 gears. Need 3.73 or greater carrier. They're about $100.
