A Better, Beefier Ball Joint
Keller Ball Joints fix the weakest part of OEM ball joint design—the snap ring. We eliminated that snap ring and replaced it with a threaded chromoly housing that won’t push through your arm. If you want a ball joint that can handle big lifts and heavy machines without pulling out, Todd Keller’s original two-piece design is still the best you can get. So put Keller Ball Joints on your Polaris RZR XP Turbo—you won’t regret more breakdown-free weekends.

The Most Durable Ball Joint Around
Keller 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, they’re made with hardened chromoly from top to bottom so they can take the heat. And since they’re easily adjustable and greaseable, you can keep them running smooth for years.

Ride Your Way
Lift your RZR Turbo, 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
