Common Questions
Why should I upgrade from OEM Polaris ball joints?
OEM Polaris ball joints are often built to a cost target and can be a weak point, prone to snapping under extreme off-road stress. Our heavy-duty joints are engineered with superior materials and construction for significantly greater strength and durability.
What makes the Black Ops Machine joint stronger than others?
We use a 4340 chromoly housing and a 300M aerospace steel stud, materials known for their exceptional strength and impact resistance, far surpassing standard OEM components.
Can I adjust the preload on these ball joints?
Yes, the included 6061 aluminum adjustment cap allows you to precisely set the preload for your specific riding style and suspension setup, improving handling.
What does it mean that they are rebuildable?
It means you can disassemble, clean, re-grease, and reassemble the ball joints. This allows you to restore like-new performance, extend the lifespan of the joint, and save money compared to replacing the entire unit.
What Riders Are Saying
Snapped an OEM joint on a rock garden and limped home. Put all four Black Ops joints in and the difference in confidence is immediate. These things are built for the way I actually ride.
— John D., Arizona
The rebuildable design is what sold me. I can pull these apart, clean them, and re-grease in under an hour. Two seasons in and they're still dialed. Best suspension upgrade on my RZR.
