I have a 2012 JKUR 6-speed also, and I loved the stock gearing with the rubicon tires in the mountains. My jeep would pull itself around in 4hi like it was in 4lo...no throttle needed unless I was in a really steep area. Now that I'm on 35s, I'm dying for a regear. I will install 5.13s from yukon, with chromoly axle shafts, and Tom woods rear drive shafts. Should be very interesting with the magnuson...called them yesterday about a purchase, so this may all be happening sooner than expected.
