Need different axle ratio.

I have my JK now almost six months and I never used 5th and 6th gear and I don't like the gearing at all for my use, I live in the mountains and never hit the highway and think that a different axle ratio than the one I have now (3.73) would fit me better.
Where can I buy a different setup and will a different ratio mess up the speedo also?

4:10s...................... I think it actually is an option for any of the JKs not just the Rubi. I am assuming that the tires are still the stock size. If you have larger tires you may want to go further than the 4:10s.

4.10 was available on all models in 2007 and only Rubicons in 2008. You can buy take offs for cheap. You also need to think about what size tires you are going to run. Let's say you go up to 33's, which is quite easy and inexpensive to do, then 4.56 would be better, especially in the mountains.

You won't notice any difference between 4.10 and 3.73. it really isn't worth the money for that little of change.

Just wondering about how much in labor it costs to get re-geared? That is one thing I'm not really willing to do myself.

Parts and labor for a regear is usually in the 1200 range.

$250-500 per axle depending on location.

Cost to regear for me. 5.10 gears front and rear with small overhaul kit--$780. Estimate to have put in---$300 front, $350 rear. Cost for power programmer to refigure speedo and shift points----$170. Total to regear $1600----From what I heard on the difference of the drivability----priceless

Yeah, 4.10 won't make much difference from 3.73 and is definitively not worth the money so I'm thinking about the 5.13 ratio and let the install do by someone who's done it before instead of me laying on the garage floor for a whole Saturday and ten cans of beer later concluding that I better take it to a shop.
I found a local place called PhatJeeps just a couple of miles from here in Rollinsville, CO and I will contact them to see if they can take care of it.
This will be the first mod I don't do myself but I have a feeling that it's in everybody's best interest that the pro's take over although I do like drinking ten cans of beer on a Saturday.
Hmmm..., maybe a group meeting and a lot of beer and brats and installing my gears?

I will contact PhatJeeps......

5.13 will be too low just for 32's, especially since you have the manual transmission. 5.13's work great with my 35's. I say 4.56 will do nicely for your needs. I still have my 4.10's laying around.
