Instead of using a snap ring to hold the ball joint in, we use a threaded chromoly housing that can't get pushed through no matter what. Todd Keller's original design is still the high bar for ball joints that can't pull out. And if you're riding with a lift and big tires, Keller Ball Joints for the Polaris RZR Trail S 900 will last longer than just about any other ball joint out there.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThe Most Durable Ball Joint Around\u003c\/strong\u003e\u003cbr\u003eKeller Ball Joints aren't just the first threaded ball joints on the market they're also the most durable. Once you press the joint into your arm and thread the housing on the back, there's nothing that's gonna get it out. Plus, the housings are made with durable tool steel and the stud is made from a high-quality chromoly alloy so they can take the heat. And since they're easily adjustable and greaseable, you can keep them running smooth for years.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eYou Need Keller Ball Joints\u003c\/strong\u003e\u003cbr\u003ePut Keller Ball Joints on your RZR Trail S 900, quit relying on a flimsy snap ring, and forget about breaking your ball joints.
