I've had the other "adjustable" ball joint style, and hated them. Still has to fight the snap ring, pretty much had to remove the a-arm every time they needed adjustment, and they just weren't impressive. Went back to stock even! I really like these, install is easy, and seem very well made. haven't had them long enough or needed any "customer service" to earn a perfect 5 star rating, yet.

Ordered these for my ‘17 xp 1000. We race GNCC a and several local series ( IXCR, AWRCS etc). These joints hold up to the toughest woods racing on the east coast. I used another after market ball joint that cost the same but they were not nearly the quality of these. There boots were junk, they weren’t rebuildable, harder to service and the company was difficult to work with. Todd Keller is a great person who sells a great product.

I just purchased and installed the new Keller Performance ball joints on my RZR 1K and these are built right! Extremely high quality... you get what you pay for. Also - great customer service and very quick to get back to me.

Easy assembly. clean paint where ball joint contacts inner A-arm hole. Grease hole position not controllable. Access to one of mine the other wheel will have to be removed. I am pleased at the workmanship of this product. Should last for years if lubed as per instructions. Installed on RZR 1000 Desert Edition upper A-arms.
