simplybao Cool, thanks for the guidance!!! I have a requirement to stay at my 2" lift and 31's...the other half has dictated no higher

But I've been contemplating getting Rubicon axles for front and rear so if I did that, then I'd get them with 4.10's.....

Jerry Bransford A 3.07 ratio generally makes a Jeep a real dog. Regearing is a commonly done thing that can completely transform a Jeep once bigger tires are added. However, at the $1200-1300 it typically costs, you don't want to spend the $$$ until you're at a tire size that you think you'll be staying at for a while. For 31" tires, I don't think I'd regear yet. But if you get tires bigger than that, then it's time to regear to a lower ratio. Auto trannies are far more forgiving of mismatched tires sizes and ratios so if you're fortunate enough to have an auto, that will help.

simplybao SWEET! Thanks for all the responses. So now my question is, I see alot of people re-gearing to 4.10 and higher. Is it worth it for me to re-gear? I may be just mis-informed but isn't a 3.07 not very desireable?

Jerry Bransford Yep, a 27 tooth is what you want and the tag confirms you're running 3.07 axles.

Todd4a Looks like a 3.07 to me.

Help with gear ratio and speedo gears..

I think that I have 3.07 gears but am not sure. Here's a link to the tag that is on the front differential cover.

Assuming that I have 3.07 gears which speedo gear do I need to get? I'm running 31x10.5 BFG's. Based on

http://www.4x4xplor.com/speedo.html

It looks like I need part number 52067627 i.e. 27 teeth

This is the tag on then diff cover:
