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
You'll get not only strength but also convenience. Each ball joint comes with a greasable zerk, for easy access and maintenance. 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.
