Opinions on ball joints

So I need to replace ball joints, upper and lower. Desert Rat Offroad loves teraflex, so they recommended them. I also found USA Alloy has "heavy duty" ball joints, specifically marketed for large tires and lift, with some good reviews and some bad. Spicer also has ball joints, don't seem to have anything special about them, just a non-oem part

I have an unlimited 4.5" lift with 37" tires. Suggestions or experiences with any brands is welcomed.

I ran synergy on my 08 JKUR for over a year till I sold the jeep. Ran 37s, and wheeled it regularly. Never an issue.

The 07 I had with 35s, had moog joints. Don't waste your time with those, they had to be replaced three times (warranted).

My Rubicon only has about 10,000 miles on it, so the factory joints are still tight.
But when they go, and they will, then I will replace them with the Synergy....

Looks like Synergy wins, by popular vote. Thanks for the help everyone.

OP, Yep, but Desert Rat is a good company to deal with.
I have used the one on Cave Creek, and Bell many times on my previous wrangler TJ.
I use to go on runs with the original Owner, back in the 70s!!!! But I have know idea who owns it, as of current.

Dynatrac gets my vote! I installed them on my '14 Rubicon Unlimited alongside my 3.5" lift. The joints are incredible when compared alongside the OEM units.

I believe they are still running $100 off and I believe that some vendors like NorthRidge4x4 are offering an additional 10% (don't quote me, but I believe that was the last thing I heard). So with the two discounts stacked, you can probably get the $500 set of joints for roughly $350.

Dynatrac are by far the very best you can get,
You will never need to replace then again.
If you buy them today...TODAY is the last day for the $100 Rebate.
Down load the form from Dynatrac.com

Dynatrac are certainly among the best but what are we missing that makes them the "very best"? The discount?

My guess is the rebuilding part. I've never seen a rebuild done yet or any other joint wearing.
I have seen failures due to manufacturing defects with Synergy and alloy.

I would agree. I spent quite a bit of time researching ball joints before I settled on the Dynatrac ProSteers. Other than price, I couldn't find any negative feedback on these joints and as kjeeper mentioned, not one reference to someone having to rebuild a set.

I was very impressed with their customer service and the quality/workmanship of the ball joints. I ordered the joints specific to 2012+ Dana 44 from NorthRidge4x4 and Dynatrac had to build up a set as they were out of stock. I had them on my doorstep in 4 business days.

And best of all, made in the USA!

What these guys said, We run rocks here in Arizona and the shop I use has been around since 1954. They rock hard in their rigs and have never had to rebuild or replace a Dynatrac yet, and that's good enough for me.
I just built my Rubicon X and I went with these while they had my axle out for the Artec Truss's and the MC Lift.

Good point. Rebuildable parts usually require more regular maintenance but I've use Dynatrac diff covers, they many not look exciting but they are bomb proof. I slid at angle of a sandy ridge (which I shouldn't have been climbing in the first place) that gave in while I was trying to climb it, and hit a big rock while sliding backwards. It cleared the bumper but slammed straight into the rear Dynatrac diff cover. My JK hit hard and pivoted. There were some scuff marks but it held up.
