Polaris RZR 900 Heavy Duty 4340 Ball Joints

Heavy-Duty 4340 Ball Joint

We spend countless hours engineering our ball joint studs. Our hardened 4340 stud is black oxide coated and wider at the base. What’s that mean for you? Test after test shows that this ball joint is nearly 2x stronger than stock. Our 4340 ball joint will stand up to abuse ride after ride.

The SuperATV Difference

At SuperATV, we understand the importance of strength but also longevity. With an adjustable steel on steel design, you're in the driver's seat for miles of reliability. 

Fits both upper and lower A-arms.
