Gearing question

I have. 2013 4dood jukebox with a 3.21 gearing. Everything I have read says that to run 35s and still use overdrive and run decently on the highway I need to re gear to at least 4.10 I have stock Dana axels. Do I need to buy em
Tire rebuild kits or just the ring and pinion. I would also app any suggestion on brand. This is a DD with very very little OR use at all. Lots of highway and I am wanting 33s or 35 at most on it.

Thanks for any advice

Not saying you can't install your own gears, but you need or need access to special tools and if it goes wrong you just wasted a ton of money.

as for 35's on 3.21.. it will be a dog. I run 35;s auto trans on stock 4.11.. and its okay for street and trail 4.56 would better.

The best bet for installing gears is to find a good shop. They know what to buy and how to install things correctly. And they give you a warranty on their work.

If you're a good shade tree mechanic with the right tools you can learn how to install gears yourself. But even many professional mechanics don't bother to do gears themselves.

If you're going to the trouble to change gears, I wouldn't go less than 4.56. If you tow a lot or live at high altitude (or both), you'd be better off with 4.88. 4.10 gears will work but if you're going with new gears you're better off doing it right.

If you want to run 35's, I'd go to 4.88's. At the very least 4.56's and that is only if you never tow anything and live in a flat area.
