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 breaking.
The Standard for Strength
Two-piece 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.
You Need Keller Ball Joints
Put Keller Ball Joints on your RZR 570, quit relying on a flimsy snap ring, and forget about breaking your ball joints. When you go on hard ride after harder ride without having to replace a ball joint, the only thing you’ll regret is not upgrading sooner.
