A Ball Joint Like No Other
Keller came up with his
original two-piece design to get rid of the flimsy snap ring that OEM ball
joints use. Our Polaris RZR 570 Ball Joints use a threaded chromoly housing
that attach securely to the A-arm. This lets you run bigger tires and go on
wilder rides without worrying about your ball joints getting pushed out and

The Standard for Strength
ball joints aren’t like other ball joints. The joint presses into the arm and
the housing threads in on the back. It pinches your A-arm so that nothing can
push or pull it out. Plus, the stud and housing are made from hardened
chromoly steel to keep it from cracking in heavy hits. To top it off, it’s
easily adjustable and greaseable—you can keep it running like new for years.
