The Heaviest-Duty Kawasaki KRX Ball Joint Available — One Part Fits Upper & Lower

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.

Why Kawasaki KRX Riders Choose the Black Ops Machine HD Ball Joint

• 4340 Chromoly Housing & Support Cup – Significantly stronger than OEM cast components — built to handle hard impacts, rocks, and aggressive off-road use without cracking or deforming.
• 300M Steel Stud – Ultra-high-strength aerospace-grade steel — the strongest practical stud material available for this application.
• Fits Upper & Lower Position – One part number covers both the upper and lower ball joint on the KRX — simplifies ordering and stocking a spare.
• CR/Neoprene Dust Boots – Upgraded boot material that resists tearing, cracking, and contamination far better than OEM rubber boots.
• 6061 Aluminum Adjustment Plate Cap – Lightweight, corrosion-resistant, and allows for precise adjustments.
• Fully Adjustable & Rebuildable – Disassemble, clean, re-grease, and reassemble — extending service life far beyond any sealed OEM joint.
• Direct Replacement – No modifications or special tools required for installation.
• Sold Individually – We strongly recommend replacing all ball joints at the same time.

Why Rebuildable HD Ball Joints Beat OEM Sealed Joints

OEM Kawasaki KRX ball joints are sealed units — when the boot tears or the joint wears, the entire unit must be replaced. The Black Ops Machine HD ball joint is fully rebuildable: disassemble, clean out contamination, re-grease, and reassemble. This dramatically extends service life and reduces long-term cost. The upgrade to 4340 chromoly and 300M steel directly addresses the material weakness that causes OEM ball joints to fail under hard impacts and repeated stress cycles. The fact that one part fits both the upper and lower position simplifies your parts inventory — one spare covers both positions. Always replace all ball joints on the same axle at the same time.

Real Riders, Real Results

"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."
