locker
 

What locker should I use in a dana 30?

Need a ton more info. Like what is your setup, terrain you ride, is it daily driven, do you mind a bit of noise and what's your budget?

With what size tires?

There's 2 types auto cheaper and selectable costly. There's tons of info on each.

Arb

Lincoln.

Not in a dana 30 with unit bearings

I run Detroit Lockers in my D30 and Chy 8.25, they are quiet and high quality unlike the lunchbox lockers.

8in lift 35s 410 gears rear locker daily driver rocky terrain prefer no noise 600$ or so

Go with a Detroit locker

for the front, i would go with a selectable locker like ARB or OX. especially if you drive it in the snow in 4wd.

You already swapped the out the gears and are just now considering a locker? You're doing (and paying for it) twice.

What locker do you have in the back axle?

A factory locker

Cherokees never came with factory lockers. You might have a limited slip but that's not the same thing.
