EXTREME DUTY "Bolt In" Polaris Ball Joints

The fix is finally here!!! The Blackops HD Lower and Upper BOLT IN ball joints fix the issue we’ve all been dealing with. These are the heaviest-duty Polaris ball joints you can find on the market. The housing and support cup as well as the stud are made from 4340 chromoly and 300m steel, respectively. The dust boots are made from CR/Neoprene, and the adjustment plate cap is 6061 aluminum. The Pro R lower ball joint threads have also been changed from 12mm x 1.5 to 16mm x 1.5 making them BULLET PROOF!

These are Unleashed Racing APPROVED! With over a season on our Pro R and Turbo R race cars and 0 failures! 

The ball joints are fully adjustable and rebuildable –– allowing them to be fully disassembled, cleaned, and re-greased to ensure you can keep riding longer, faster, and harder with the minimal amount of long-term maintenance possible.

While we do always recommend replacing all of your ball joints at the same time, we sell them individually.
