They’ll be backordered a while, but worth the wait.Revolution gear and axle
Correcting the axle gear ratio is some of the best money we can spend on our rigs. I remember one of my first reactions after installing the new gears: Why didn't I do this sooner?!After months of waiting on freight and waiting for an appointment at the dealer, I finally got the installation done this week. The drivability of the jeep has improved significantly and it gets to the power band more easily. Also, I didn't notice over-revving at speed at higher gears either. Obviously I haven't pounced on the jeep until the gears are broken in so I haven't tried hard launches or anything to see the full effects but overall I'm happy I went with the 5.13s even with the 33s I have now.
True, Reminded me how my previous JK2D felt. As if the Jeep forgot it had oversized tyresCorrecting the axle gear ratio is some of the best money we can spend on our rigs. I remember one of my first reactions after installing the new gears: Why didn't I do this sooner?!

If they did get vibes there is no way to balance the driveshaft. There are no machines available capable of balancing at that speed. If you get the gears plan on either re-gearing again or spending well in excess of that to get locking hubs. Nothing wrong with getting whatever gears you want but be prepared for the outcome. Planning on not having problems is poor planning. Just because one or two didn't have vibes doesn't mean you wont, it's just a roll of the dice no matter how many times you ask.Did you ever get the driveline vibes some have had with going to 5.13 gears because of driveshaft rpm's?

Diggin up old thread... Sorry
So after having the 5.13 gears awhile what's your opinion of the performance now?

I'm about to make a decision on which gear ratio I will go with (also considering 4.88). My Jeep is a 2006 LJ Rubicon with the dreaded 42rle Auto Tranny, 33 inch tires. Illinois is pretty flat.
You'd definitely regret 4.56. I'd decide strictly between 4.88 and 5.13. Personally I'd go 5.13.This is exactly why I'm leaning hard towards 4.88 gears. I dont want to be spending money for a long time chasing vibes down. My Jeep has only 40k miles on it now, Im hoping I will be one of the lucky ones that get by without driveline vibes. I have read and read threads and I just cannot talk myself into 5.13 gears. If I decide on 4.88 I hope I will never regret it.

Even Tom Woods says it's too fast for them to balance.
Ask a few local gear shops that you are considering to do the install, nobody here is going to cover the work if there are vibes. No gear shop I've ever talked to would recommend these high ratios. Even Tom Woods says it's too fast for them to balance. No matter what decision you make you'll have second thoughts, that's part of life. These ultra high ratios aren't what they make them out to be, most people with those ratios don't daily drive their rigs anyway.
I've never heard this. Is this true @Shawn at Tom Wood's ? Funny thing is I regeared to make the street driving better. Off road didn't care quite so much, though it was noticeable.

I regeared for the same reason with 4.88s and 32s the 1st time when I got the demon vibes. When I went to 33s, I drove with 4.88s for a while before I decided I wanted 5.38s, it was that miserable. I don't know what is more painful to live with, demon vibes or an undergeared jeep that you drive on the hwy. Most people would choose the former if asked that question I guess .. but it SUCKS driving an improperly geared Jeep if you live in a hilly area. I simply don't understand how people do 3.73s and 33s or whatever.
