What size tires are on it now?

You don't necessarily need different axles unless they're not strong enough for that tire size and for how you use the jeep. You can regear the stock axles to a certain point to regain that lost performance.

Crawl under the jeep and look for a tag attached to one of the diff cover bolts, either axle. Let us know the numbers on the tag and it should contain your axle ratio. We can recommend a good gear ratio to regear to with that number and your current tire size.
