A Better, Beefier Ball Joint
Keller Ball Joints fix the
weakest part of OEM ball joint design—the snap ring. We eliminated that snap
ring and replaced it with a threaded chromoly housing that won’t push through
your arm. If you want a ball joint that can handle big lifts and heavy
machines without pulling out, Todd Keller’s original two-piece design is still
the best you can get. So put Keller Ball Joints on your Polaris RZR Trail S
1000—you won’t regret more breakdown-free weekends.

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
housings are made with durable tool steel and the stud is made from a high-
quality chromoly alloy so they can handle heavy hits. To top it off, it’s
easily adjustable and greaseable—you can keep it running like new for years.

Ride Harder
Who needs these RZR Trail S 1000
Keller Ball Joints? We can answer that with another question: have you ever
replaced a ball joint before? That’s right—if you’ve ever wore out or busted a
ball joint, then you’ll save time and money upgrading. And if you haven’t yet,
upgrade anyway so it doesn’t. They don’t use a weak OEM-style snap ring, so
they can handle your loaded machine better. They’re perfect for people who
like to spend less time in the garage, and more time wheeling hard with big
tires and big rides.
