I'm interested to see if these EMF joints hold up better than the original MC joints.
I bought a Johhny Joint to replace my MC heim joint but wasn't comfortable with that experiment and never installed it. So I have a MC track bar with a bad heim joint, a new replacement heim joint, and a JJ that could be swapped for the heim joint. I don't plan to use any of this stuff.
My (hopefully final) solution was to buy a Currie Rock Jock track bar and be done with it. I called and they agreed to swap out the axle-end JJ with one that works with a 9/16" bolt. It is installed and just clears everything with my 2" lift. If I didn't have adjustable CAs (savvy uppers, Currie lowers) shortened up to their minimum length, I'm pretty sure I would have clearance issues.
