Gears can be changed in any axle you pick up. Just be warned that doing that will cost you a couple hundred dollars. Check your jeep for tags on the diff covers to see what you have. If you need one with 3.73 gears I might know of one that would work for you.
I like the arms, they are a good solution, but they really aren't worth the effort for the average person and you already see the BS that goes on over bushings VS JJ's, the crap that would go on over J arms would be epic.[/QUOTE]
