These are the heaviest duty ball joints you can find. The housing and support cup is made from 4340 Chromoly steel, the stud is made from 300m steel, the dust boots are made from CR/Neoprene, and the adjustment plate cap is 6061 aluminum. They are fully adjustable and rebuildable! These will keep you riding longer, faster, and harder than ever before with the least amount of long-term maintenance possible. You can fully disassemble, clean, and re-grease and you are good to go for miles and miles again.

1. Place the ball joint in the freezer for an hour, or two
2. Jack car up off the ground
3. Remove wheel
4. Loosen ball joint nut
5. Pry ball joint up from the back side
6. Pull lower arm down and out of the way
7. Use vice grips to hold socket over ball joint and hit socket downward with a hammer
8. Heat the metal where the ball joint will be installed with a torch (not red hot, just enough to make it slightly expand)
9. Get the ball joint out of the freezer and put it in the arm as quickly as possible
10. Put everything back together and you are good to go

*** We always recommend replacing all of your ball joints at the same time. Or at least both upper, or both lower at the same time. ***
