Yeah I am curious about that too. A guy I know who isnt a XJ guy keeps telling me that 4.88 is the way to go with my 33's. At the moment I am running the 33's on I believe stock gears (I havent checked for sure and not sure how to check lol).
 
I havent had my XJ on the freeway to get going to 65. I will have to try this though and see or see when I hit 2000. I have automatic :).
 
I'm sitting at 32s not 33s, but I think my Jeep, 4.0L AW4 auto, 3.55 gearing is at like 2100 at 65 mph. It feels a little like a dog, I'm considering buying the Rusty's 4.56 gear package for my Jeep and installing it myself even though I've never done it. However a friend has, so maybe a case of beer will be in order.

4:88's will be good with 33's and also with 35's but there's a strength issue because the pinion gets really tiny at that ratio. I would suggest 4:56 and if you eventually go up to 35's then a low range kit in the transfer case.

Humm.. so I should go with 4:56 instead if I just want to run 33's for awhile and avoid the extra work and $ ?

I am in the same boat and 4 wheel parts quoted me 1245 for parts and labor which seems a little high but I am not sure. Who does everyone recommend for gear installed instead of 4 wheel parts?
