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.
The 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.
