Depends on what size tires your running. I'm running 37's with 516 gears and at 70 I'm at about 2600 with 6 speed trans. Now I have the 3.6. If you have auto and 3.8 it will be different. There are charts for this though. Just google it you will find it

I'd say 5.13's since you can have the ability to upgrade to 37's one day. Plus your tires are closer to 34's when measured out and thats the top end for 4.88 gears.

Otherwise, with 35s and normal offroading, you are golden with 5.13s.

I'm not real familiar with gears. Again I was told that for a Dana 30, 5.13's would be real tight in the diff. housing and that it would have very little tooth contact. Is that true and is that something to be concerned about. I dont beat it up, usually slow and steady. and my wife drives it as her daily driver for now.
Thanks again. It looks like I'm going with 5.13's. again. It's like a game of tug-o-war in my head.
