Re-gearing?

So I was told the best way to maintain power after bigger tires are installed is to re-gear. How is this done? Does it have anything to do with mine being a 6-speed transmission. I know it has something to do with axle rotations, but that's about it.

Sooooo, not exactly sure what you are asking here; are you asking how to re-gear? Or are you asking about the concept of re-gearing to make up for power loss after upgrading to larger tires??

you need to regear both front and rear axles (with the same gearing). You get a new ring and pinion gear for both axles.

what jeep do you have? What tires are you running?

I'm guessing 33's or 35's so i'd run 4.56's for 33's or 4.88's for 35's...

It's actually kind of pricey so do research to get it right before doing it...dealers charge around 2K to do a regear.

I'm not expeirenced enough to do something like this myself so i'm sure others can chime in on this though...i'm going to have a friend do mine as a side job for 500 (works at a jeep dealer)

I have an 06 2.4L wrangler, and yeah it would be for some 33's.
@rutdigger, more so about the concept because I just recently heard about this.

Hey bro..this will give you and idea of what is involved:

Pirate4x4.Com - The largest off roading website in the world.

But the concept is simple. Think of it like this. When you go to a larger tire you need more rotational force to get the tire moving and keep it moving. You are adding more weight also. By re-gearing you are using a mechanical advantage to add more torque to your axles. The trade off is that it will increase your RPM's faster. But, anyway, that is the nutshell of it.

Dang, that looks intense. There is a lot going on when it comes to re-gearing.
Thanks for the link, it is very informative.

Yes Sir, there is. It is one of those things that you can't get "close"..it must be exact. Now, that doesn't mean you can't do it yourself. You must have the knowledge to do it and the tools, but you can do it..

If I DID do it myself, it sounds like I would save about 1,000 bucks.

Regearing is not that bad. $300-$500 per axle not including parts. Depending on where you live. Find a guy that has a drag car, buy him a case of beer and tell him you would like to learn.

Thats not far off the truth. When I did my gear swap myself I had a guy downtown that I could goto when I had questions about the gear patterns. Now, I have done mine and my buddies and am about to install lockers..lol
