Top-Shelf Ball Joints for a Top-Shelf UTV
The RZR PRO XP is at the cutting edge of UTV performance, but its ball joints have the same weak spot they always do. A hard ride can easily push your OEM ball joint past the flimsy snap ring. That’s why Todd Keller built a two-piece ball joint that eliminates the snap ring and improves overall durability. Put Keller Ball Joints on your Polaris RZR PRO XP—their better design and tougher components let you ride harder without breaking down.

Top-Notch Durability
Few machines can beat the PRO XP when it comes to raw power and performance. Keller’s two-piece ball joints are built for exactly that kind of machine. The two-piece design threads onto your A-arms like a nut and bolt to make it virtually impossible to push out. The stud and housing are both made of hardened chromoly to make sure it can handle any hits. To top it all off, Keller Ball Joints are greaseable and adjustable so you can get optimal performance for years of riding.

Take Your PRO XP to the Next Level
Nothing beats getting a huge lift and upgrading to massive tires, and with Keller Ball Joints on your RZR PRO XP, you can go big and ride hard. Without a flimsy snap ring waiting to fail on you, you’ll spend more time riding and less time replacing ball joints.
