Thanks everyone for the replies.

I did not think about regearing the front, just shows what little I know about all this stuff. I am loving learning about my jeep and all the options I have to make it the way i want it. I haven't touched the gears since I bought it...it is a 2010 Sahara.
I have an automatic transmission and plan to go to 35 inch tires when they need replaced.

Since you are thinking you want 35's then most people with the Auto will go with a 5:13 gear as I have too.(highest numerical you can go b'cause of your front dana 30) Since you have the 4-door, I would recommend the 5:13's.
I don't think you can go wrong with the ARB, but would ask you shop if they are going to install the compressor and wiring so you can operate it.

Should I regear the front axle too?

Loadbreak

You will need to regear both front and the rear at the same time. If would be like having your front turning at say 30 mph while your back is turning at something like 20 mph. Not good.

Your driveshafts are connected the pinion gear at the axle housing which meshes with the ring gear in the axle housing at a certain ratio. The axles connected to that ring gear transmit that your tires. The ratio front and rear needs to be the same.

Depends. Ask yourself a few questions:



Do you ever want to use 4wd?

Can you afford to replace the tcase and whatever else you trash by putting it in 4wd with different ratios front and rear?
