Is there a thread im not finding about gearing that explains it best? Just got a 2000 sahara with 307 gears and want to upgrade to a 2" lift and 31's or 32's...I'm allready at 2800ish rpm at 80mph so would rehearing help that? It's my commuter car and weekend fun vehicle. Would goin up to 410 help alot? How much does that cost normally? 4.0 auto with d35s

There are plenty of charts out here to show you the best gears for your tire size. You also need to consider your transmission. Unfortunately I have failed to copy said charts, so I can't show you one right away...

Expect to pay $500-800 per axle for parts and labor to regear. It is recommended to have someone who does gears all the time install them, since they require special tools, skills and patience... Both axles must be regeared to use 4WD. 4:10 are pretty low for 31" tires I think. But since that's what is stock on a Rubicon, I guess it's probably about right...If you don't plan on using any bigger tire than 31's I don't know that I'd go to the expense of regearing. I have 3:07's with 33's, but my terrain and driving style don't really make them a problem. It doesn't have the pick up that the Rubicon does, for sure, but I just kick back and enjoy the scenery as it goes by...
