I just picked up a Synergy Set from Ebay for $100. They gave me a great deal. They are the older model, but they are the warranty replacement version when they had that bad run back in 2017 and apparently they had to replace a bunch of them. I do like that Synergy fessed up to it on their website. Here's what the dealers have on the bottom of the item listings: *If you have older Synergy MFG 8009-1201 or 4120-01 ball joints that did not live up to your expectations, Synergy MFG has extended the warranty period for ball joints manufactured in 2016 and 2017 that experienced premature wear.
