Mevotech made in Canada, arguably the best quality available these days.
The new tariffs are going to hit your wallet though.
Someone posted the discount numbers a while ago.

Here’s a low friction ball joint from Maximum Motorsports.

First, don't delay in swapping them out.  My wall of shame has a ball joint out of my buddy's '95 Cobra that fortunately let loose in my driveway.  The OEM ones are not terribly well made.

Second, I will second Rudi's endorsement of Mevotech.  I only buy their chassis parts now.  I had a set of MOOG lifetime tie rod ends on one of my F250s that only lasted 20k miles before they started clunking.  I reached out to Rock auto to get replacements and they asked if I still had the boxes (of course I didn't the parts were over a year old at that point).  They asked for a picture of the MOOG logo cast into the parts (there wasn't one, and I also noticed there were no grease zerks either).  They wouldn't warranty them, even though I found the receipt from when I bought them.  Then I read on here where at some point they were putting TRW or some other brand parts in MOOG boxes, selling them as MOOG lifetime and then not honoring the warranty since the parts weren't really MOOG.  I won't give my money to businesses which operate like that.  Mevotech is Canadian and all the parts I've received from them have been first rate (I only buy their top of the line).  I've rebuilt the front end in both my F250s (ball joints, tie rod ends, drag links, track bar ball joints, sway bar bushings, swap bar end links, and unit bearings).  Everything was high quality, installed easily, and has held up (about 30k on the one front end now and still as tight as when I first did the work).
