Standard Duty Ball Joint
For strength that’s as good or better than stock, get our standard duty ball joints. With a zinc-plated chromoly steel construction, they’re built with reliability for the casual rider in mind.
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.
