Stop replacing weak OEM Kawasaki KRX ball joints that fail under hard use. The Black Ops Machine HD Kawasaki KRX Ball Joint uses 4340 chromoly steel for the housing and support cup, 300M steel for the stud, CR/Neoprene dust boots, and a 6061 aluminum adjustment plate cap. Works for both the upper and lower ball joint position on the KRX. Fully adjustable and rebuildable. Sold individually; always replace all ball joints at the same time.
Are these ball joints truly rebuildable?
Yes, our HD ball joints are designed to be fully disassembled, cleaned, re-greased, and reassembled, significantly extending their service life.
Can I use one ball joint for both upper and lower positions?
Absolutely. The same Black Ops Machine HD ball joint is designed to fit both the upper and lower ball joint positions on your Kawasaki KRX.
What is the benefit of 4340 Chromoly and 300M steel?
These are high-strength, premium materials that offer significantly superior durability and resistance to failure compared to standard OEM components, especially under extreme off-road conditions.
How many ball joints do I need to order?
We sell them individually, but we strongly recommend replacing all ball joints on the same axle at the same time for balanced suspension performance and safety.
Replaced all four ball joints on my KRX after an OEM lower failed on a rock. Two full seasons on the Black Ops HD units and they're still tight. The rebuildable design and the fact that one part fits upper and lower makes maintenance simple.

The chromoly housing and 300M stud are immediately noticeable in quality compared to OEM. These are in a completely different league. Best suspension upgrade I've made on my KRX 1000.

Stop replacing weak OEM ball joints. Upgrade to chromoly and 300M steel — rebuild instead of replace.
