Keller Performance Products Keller Ball Joint for Polaris RZR 900

Stock ball joints use a weak snap ring to stay in place, and when you're hitting the trails hard, that snap ring can fail fast. That's why Keller designed a smarter two-piece ball joint that ditches the snap ring altogether. Plus, the entire joint is made from tough chromoly steel. Upgrade your Polaris RZR 900 with Keller Ball Joints to send it with confidence - and forget about busted joints holding you back.

A Tougher, Stronger RZR 900 Ball Joint

If you've gone through your fair share of stock ball joints, it's time for an upgrade. Kellers two-piece design presses in and threads together, locking it to your A-arm like a nut and bolt. That means it won't pop out when you push the envelope. It's made from end-to-end hardened chromoly steel to handle serious abuse. Plus, it's greaseable and adjustable, so you can keep it performing like new year after year.

Built for Any Rig

Whether you're rolling on stock wheels or towering over the competition with monster mud tires, these RZR 900 Keller Ball Joints can take it. Since they don't rely on a weak snap ring, they can handle more weight from huge upgrades and wilder rides without failing. Get a set and ride harder without worrying about blown-out ball joints.
