An Innovative, Two-Piece Ball Joint
The biggest problem with OEM ball joints is that they're held in by a flimsy snap ring. All it takes is one big hit to push right past it and put a stop to your ride. That's what Keller Ball Joints are built to fix. They use a threaded chromoly housing that won't pull out just from hard impact or running huge tires. It's no wonder why the original Keller design is still the best for your Polaris RZR Trail 900.

The Industry's Best Durability
Keller Ball Joints were the first threaded ball joint on the market. The joint presses into the A-arms and then the housing threads onto the joint giving you a nearly unbreakable ball joint. The housings are made with durable tool steel and the stud is made from a high-quality chromoly alloy for incredible strength. To top it all off, they're easily adjustable and greaseable so you can keep them running smooth for years.

Ride Your Way
Lift your RZR Trail 900, put on massive tires, and go hit some jumps! By eliminating the need for a weak snap ring, Keller Ball Joints can handle every kind of extreme ride. They're designed to stop your weekends from being interrupted by a pointless ball joint break.
