their are ton of them out there, but really you just need the rotation and easily greaseable and replaceable joint be nice.....if you want to dump crazy money on them for sure they will more than oblige you, lol...…
mazulla, cognito, krypto and Ben @ filthy motorsports recommended SPC (adjustable and easily replaceable ball joint) to me, though they didn't have one ready last I checked
the camburg tubular is a better deal and more than enough....
RC, readylift and all susp lift co have them as well and would fix the issue and be way better than stock...….as long as your not smashing whoops at 60 MPH.....
you can spend $400 or $1400 or go really big with this
