Sort of funny story...and sort of not....
I recently regeared and the shop was supposed to install 5.13's at my request. When I got my Jeep back I could immediately tell the difference in power. It was night and day type of difference, and since my Jeep is my daily driver I no longer have those white-knuckled merges when entering highway speeds.
Anyhow, after the reagear I was having major issues running in 4WD and long story short it turns out the shop put in different gears - a 5.13 in the front and a 5.38 in the back. The funny thing is I am so glad I had the 5.38 installed for two reasons - 1) If you look at the chart I can go up to 37's if I want to and not have to worry about trying to get more out of my gear set, 2) I tow a boat from time to time and the extra low end will definitely prove to be helpful.
Now I am just waiting for the shop to call me back to arrange an appointment to get the 5.13 gear swapped in the front to a 5.38.
Anyhow, the automatics are undergeared from the factory in my opinion - just look at the chart presented earlier in this thread and note the difference from manual to auto. My Jeep now runs better than it did with the 4.10's and stock Rubicon tires. I've got more UMPH and it's a helluva lot more fun to drive.
My $.02.

I believe the highest he can go is 5.13s as he doesn't not have a Rubicon and 44s front and rear. Either way, 5.13s should make a big difference from all I've read and heard. Still trying to regear myself.

Then again if your not doing much off roading the 5.38 would be fine and correct the rpm got on road driving.
Its all about building to suite your rig..... Right?
