Polaris RZR 900 Keller Ball Joint

Keller’s Two-Piece Ball Joints Are Built Better
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. Keller’s 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.
