Regearing question?

I'm a newb to regearing. I have a 2008 rubicon auto trans with a 2.5" RK lift and 35" toyo RTs.

I'm wanting to do 5.13 gears. What all do I need and about how much will the total cost be?
Who makes the best gears? I've read good things about Yukon.

Northridge4x4 has a master overhaul kit with 5.13 for rubicon for $599 for front and rear gears and install kit.

What do you need to replace when regearing?(other than ring and pinion of course)

I'll tell ya, I'm not afraid to do anything on my Jeep myself, EXCEPT gears. I've watched guys do them before and knew it was a little too involved for me to tackle. It was $ well spent to have a shop do it.

I got three quotes, all around $1,800 so I went with the shop I had the better feeling about and that had more recommendations from friends.

I went with Yukon, though I toyed with going Revolution (since I like my rear axle shafts from them.)

You'll also need a carrier for your front D30.

Good luck!

I have a rubicon? So do I need a carrier for the front d44? Do I need the master overhaul kit or just the install kit?

My bad, read too fast and didn't catch that part. I'll wait for others to respond, I'm not an expert in gears like many here are.

On a separate note, how do you like the RTs?

On a 2008 I would get the master kit and stick some new bearings in there.

I'm not a guru on this subject either but I'll give it a shot.

From several shops these are the parts/services I was told would be included:
Ring and Pinion
Master Install Kit
Front Axle Seals
Fluids
Axle Housing Cleaning
Front Axle Carrier (since I had 3.21 gears and changed to 4.56)
Labor
(I also needed a tuner since I have a 2012)

My quotes were all in the $1800-2000 range as well, though I actually ended up going to the shop that charged the most because they also had much more reviews and much better reviews at that (the guy who did my gears sent 4 trucks to SEMA this year so I felt like I was being taken care of )

I will also say that I don't know anything at all about brands of gears, I just know I have G2's and they work great and have a limited lifetime warranty. To quote the shop that I had mine done at, they told me Yukon gears are "junk and it's crappy steel from China" (again, I really have no substantiated claim to that other than that's what the guy at the shop told me). I'd suggest ask different places what they recommend and do a little research. One guy might say one thing, and another says something totally different. I heard a consensus from shops that G2 was good so I went with that.

Hope that helps! Good luck!

3.8 engine, with automatic and 35's, 5.13 ratio, good choice!!!

1. R&P sets.
2. Master installation kits.
3. Lubelocker gaskets.
4. 2.7 pints of gear oil for the front and 4.75 pints for the rear.

Why not just purchase the parts from your gear installer?
This way, you will have warranty on the complete install.

Make sure that the shop, is experienced at installing gears.

Also, get a copy of their warranty in writing!!!!

Good Luck..

thanks everyone for the help, time to look around for good reputable shops...

as for the RTs (35x12.5x17), they are EXTREMELY QUIET compared to your average mud tire. Ive got an 03 tj on stock 245s with the goodyear wrangler mtrs and they are much louder, also my father has a 06 nissan titan with 33" nitto trail grapplers, they are much louder as well.

as for performance aired down to 12-15psi on the rocks, they did very well, never broke a bead (i don't have beadlocks) and no gashes in the sidewall. they held up and griped very well.

I have yet to put them in slick mud, but they did grip well enough to pull out a sierra 1500 sunk to the frame in wet sand.

I chalk tested them at 38psi (too high) and dropped them down to 34psi and they ride great and are wearing evenly.

so far no problems with wet roads at highway speeds either.

overall they get my approval
