Two-Piece Ball Joints Work Better
Todd Keller saw that
snap rings just weren’t good enough to keep ball joints from popping out, so
he made a two-piece design that eliminated the need for a snap ring. Now you
can get rid of your snap ring by upgrading to our Polaris RZR RS1 Keller Ball
Joints. The better design paired with chromoly components makes this ball
joint almost impossible to push out on a hard ride.

Durability You need

The RS1 is all about being independent on
the trail. You can’t let a busted ball joint leave you stranded out in the
woods. Put Keller Ball Joints on your RZR RS1 and ride worry free. The two-
piece design presses in on one side and threads in on the other—like a nut and
bolt. Combine the innovative design with all-chromoly components and these
ball joints are practically unstoppable. Finally, you can grease and adjust
them easily to make sure they always feel like new.

Get Wild
With Keller Ball Joints

When you upgrade to Keller Ball Joints,
you can upgrade the rest of your machine without worry. Get wild with bigger
lifts and meaner tires—without a snap ring to fail on you, you can push the
limits and forget about bringing spare ball joints on your next ride.
