Hey I'm just starting to buy everything for my Navajo in lifted this spring and now I'm stuck at lockers I don't know anything about these is it something I should price shop for or should I buy a more expensive one? Just from looking the two cheaper options are Spartan and aussi I've heard a few pros about both but that can you guys tell me? I'm still debating 4inches and 33s or 2 inches and 31s I don't wanna spend more than 2grand on the build that's excluding tires but out playing the other day I noticed how much the locker would help so any info would help thanks guys!

If you're going to run bigger tires, you more than likely will need to regear your axles to compensate. If you want a locker, the best time to put one in is when you already have the axle opened up for regearing.
So I suggest first look what gear ratio you now have, then decide if you'll need to change it with larger tires, (and if you can afford to do it), then think about lockers.
