Ring and gear

I have a 2011 4 door sport Wrangler. I am going to put a 3.5” lift on with 35s. My Dana is 30f and 44r and I want to put 4.56 on. In order to do this I need a carrier that can handle. Can I get some good suggestions on gears and mainly I need suggestions on a carrier. TIA!

Whether you need to replace the carrier up front depends on what gears you have now, as I understand it. If you have 3.21 gears and want to go bigger / shorter (like 4.56) you will need a new front carrier. If you have 3.73 gears you should not need a new front carrier unless you want to go to 3.21 gears.

Find a good shop to install the gears for you. If you're not an accomplished mechanic with the right tools, you should leave it to the professionals. They will order the gears they trust and install them as a package.

If you have 3.21 gears, you will need to replace the front carrier. If you have 3.73, you won't. The rear can keep the same carrier no matter what you have. However, if you are installing gears, there's no better time to upgrade the carriers to limited slip or lockers since you're doing all of the labor for both at the same time already. The only extra cost is the carrier you choose.

Read up on the different options you have when you replace the carrier: The Basics of Differentials and Lockers

My personal preference for a limited slip is the Eaton TrueTrac. I have them in the front and rear of my XJ Cherokee and they do great all around. The Jeep is nearly unstoppable in snow (until it gets too deep).

I am a big fan of the Eaton E-Locker for a selectable full locking differential. I have them in both axles in my JK and both axles in my truck. They are undetectable on the street when off but you get near instant locking at the flip of a switch when you want it. The ARB air locker does the same and has really great reviews too.

Just use the standard spicer carrier for 3.73 and up(numerically). I think that is the break. you can buy just about anywhere. You can transfer your spider gears from the one that is in there. Don't buy the Yukon carrier as you have to buy new spider gears specific to the carrier, so more $$$. Typical empty carrier is $85 or so.

I did lockers in mine, so didn't need a new carrier(although the locker was $600 more...lol)

I don't know that you can go wrong with most of the gear brands that are out there. I picked up my Yukons on sale at Northridge 4 x 4 with the master install kit for somewhere around $600 if I remember correctly(it was 2 years ago)

Gears are not generally a DIY thing. (I have done it) The tools needed to do it right cost more than paying someone to do it. (I was able to borrow from a buddy)

Tip: When you pay someone to do it, use what they recommend and are familiar with, your end result will likely be more favorable than if you force them to install the product you supply. Someone who is really good at it can be done front and back in about 2-3 hours. It took me a week of fumbling around to get do the ones on my xj. I will let someone else do it for my JK.

I had a coach help me do the gears in my JK. And I would never do another JK without using crush sleeve eliminators. Crushing those sleeves took a 3/4" drive ratchet and a 6' long cheater bar and was a heck of a workout.

I did the Grand Wag D44's I installed in my XJ by myself. Those use shims all around so they're much easier. But I dumped almost as much into the tools as I would have spent on paying someone else to do the install.

It's not rocket surgery but unless you really feel motivated to want to do it yourself, you're better off paying a shop to do it.

Thank you all so much! I think I’m going to go ahead with the electronic locker. I will be having this professionally installed as well

FYI...If you lock the dana 30, the lockers have the same issue as the carriers. Make sure you purchase the correct one for the gears you install, but if you are having a shop do it, then they will know which one to get.

What problem are you talking about? And if I get an Eaton elocker does that solve my problem with the front carrier being too small which is why it needs replaced? The front carrier is what can’t handle the gears, correct?

He's talking about the carrier break that you find in differentials.

Read more about it here: Differential Carrier Breaks | West Coast Differentials

When you cross over that break, you need a new carrier (i.e. going from 3.21 to any other gear in the front D30).

The shop will know which side of the carrier break you are on with your upgraded gears and they will make sure to buy the correct differential when they put together your order. That's one of the good things about having a shop do it. They know the details and will buy the right parts without you having to worry about it.
