37 and what you have means no more 5th. you will kill a set of ball joints, tie rods, wheel bearings very fast too. you will be fixing that new Jeep alot and i realy do not think Jeep will warranty it.
with 4:10 and 35 on my rubi it can barley hang in 5th. unless i am flying at 80+.
I agree with this.
You can do 35's on the 3.6 without a regear. I've been running like this for a few months. An AEV Procal will make it smoother because it will correct the shift points. I would describe it as borderline. Sure a re-gear would be nice, but not a necessity.
37's and you will need a re-gear and the additional can of worms mentioned above. Also looks like you have a Sport? 35's on the front D30 is already pushing your luck. 37's and you're looking to break something or do an axle swap. $$$
