JKU ball joint recommendations

[A+J ‘12 JKUR]

Hey all — looking for real-world feedback on ball joints for JKs.

I’m running a 2012 JKU Rubicon on 37s with a 3.5” lift. I’m about to rework the front axles (regearing planned) and will be installing Reid knuckles. Right now I’m deciding between Dynatrac, Synergy, and MetalCloak ball joints — curious what people are running and how they’ve held up.

Any feedback is appreciated!

Synergy.
Run, kill, replace.
Curious what you have now.

Whatever’s in there now is whatever was in there when I got it, and rusted to death so I can’t see a name or anything.

What Andy said. Don't spend extra on any that say heavy duty or the like. They wear out anyways. Just get some basic ones and plan on replacing again at some point in the distant future.

I guess my question was if you still
Somehow on OEM or aftermarket.

These are the exact same balljoints as teraflex, Yukon, mopar etc. and are cheaper. The rebuildable and the other balljoints that are $300 plus are a waste and won’t last any longer. They all have plastic inside that wears out. These are what I would get.

That’s a killer price. Even Synergy’s just went up in price to $300 for their basic ones.

Easy way to identify is if you see a zerk fitting on top of the uppers which will mean aftermarket. If they are aftermarket, pay attention to what comes as in, if they are knurled or not.

Synergy here. I would guess 40k miles on them mostly on 37s. Zero problems.
