Polaris RZR RS1 Ball Joint

Which Ball Joint is Right for You?
We offer three levels of high-quality ball joints for the RZR RS1 that are unmatched in strength and performance. Our OE Replacement ball joint for casual UTV riding. Or choose our Heavy-Duty 4340 steel stud ball joints for rougher weekend trail rides. Need to take it up a notch? Get unmatched strength for your Polaris and choose our Super Duty 300M ball joints. Engineered to deliver all-out strength, let SuperATV's ball joints eliminate any fear of ball joint failure.

Super Duty 300M Ball Joint
300M grade steel is the strongest ball joint material on the market. We took that material and combined it with our superior design engineering to make the strongest stud possible. That means minimal narrowing at the neck and an adjustable stud. At 2.25x stronger than stock, you can't buy a stronger ball joint than SuperATV’s super duty 300M ball joint.

Heavy-Duty 4340 Ball Joint
SuperATV spared no expense while engineering our ball joints. Our shear tests prove that our unique blend of a 4340 VAR steel stud, hardened to just the right Rockwell, and then coated with black oxide gives you a more desirable combination than your standard steel material. With a PSI breaking point of nearly double OEM and other aftermarket ball joints, the ball joints will last a long time. 

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.
