Is anyone running 35" with the standard gearing of the X? Just wondering how bad they effect performance vs 33"

sure, i am in my orange jk x unlimited. 35" mtr's with 3.73 gears. not great but not too bad. i've installed a superchips and that's helped out.

i got a 2010 unlimited sport auto and i got the 3.23 on front (30 dana) and 3.73 on the rear (44 dana) and i been wondering the samething i been doing some research and the dealer say's is fine since i been think about getting my lift with them and 35's with them.

That's where I am as well, lift kit gave me more lift than anticipated for 35s, the 3.73s weren't as bad as what was bantered around and I'm waiting until the meats wear out and a move to 37s before I'll spring for gears. I'll drive in 5th or 6th at 70mph with little to no difference in efficiency, and 5th being better for rolling hills. Will likely roll with 5.13s, just want to have the tires on for a week or so before I leap.

i have a wrangker X 6speed with the 3.21 on 35, and around town isn't bad, on the highway i cant get it into 6th but it goes good in 5th. mpg r definitely going to drop. as far as wheelin goes 4high is useless, absolutely no power if your trying to go up or thru mud. i am going to save and put 4.88 in with a locker when my tree grows more leaves. good luck

Uh. Don't the gears gotta match front to back? Pretty sure they do.

Are you sure your running different ratios on the front than the back? I would think that would be causing some damage to something on the drivetrain.

Yeah they do. He's probably got 3.73 F&R. I have 3.21s and 35s and I get by. I am regearing over the sumer, but its been fine for over a year now.

x2 (superchip is a huge difference in power and gas especially for automatics)

i was thinking the same since i got the towing packege 3.73 in F&R but i was toll different
