What axles and gear ratio?

Hey y'all, I was wondering what all needs to be upgraded and changed with my jeep when I lift it. It's a 2000 with 30 inch tires, a 4.0 manual, and stock axles and gear ratio. I'm looking to get a 4.5 lift soon with 35s. What axles and gear ratio should I get?

what jeep? Depends on intended use. If it's half n half may not need to get all deep geared. If it's mostly trail toy I'd go deep in gears as the tires will only get larger from here. if you plan on polishing those axles and keeping them a while then I'd go 4.56. Should swap that rear though. If you have the lp front you may want to look into the hp 4cyl front axle. If one was lucky enough you may find a hp front with 4.10's and an 8.8 with same gears and an LSD?..

Also need to know your transmission type when recommending an axle ratio.

I would go with 4.88 on manual, and if you have a 3 speed auto go with 4.56.

It's a wrangler 5-speed manual transmission, and it's my daily driver. But I hit the mud a good bit.. Thanks for y'alls output. So what I've gotten from this is: if I get the 35s and the lift, I should swap the Dana 35 to a 44 and change the gear ratio to either 4.56 or 4.88?

4.88, and yes, that's as deep as you can gear on the TJ D30.

Consider both steering and brake upgrades to go with those 35s.
