SuperATV Polaris Ace Ball Joints
Which Ball Joint is Right for You?
Get unmatched strength for your Polaris Ace with Super Duty 300M Ball Joints from SuperATV. If you don’t need all that strength, our OE Replacement ball joint is great for casual ATV riding. Or choose our Heavy-Duty 4340 steel stud ball joints for rougher weekend trail rides. With better materials and smarter design, let SuperATV's ball joints eliminate any fear of ball joint failure. 
Super Duty 300M Ball Joint
We got the strongest steel stud material we could get our hands on — hardened and black oxide coated 300M. Then we used it to make a stud that doesn’t narrow as much as stock. The result is a ball joint that’s 2.25x stronger than your OEM ball joint. If you want to work hard and play harder with ultimate strength, you need SuperATV’s super duty 300M ball joint.
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.
