Description:

The Kryptonite KR6292 Bolt-In Upper Ball Joint represents the latest evolution of Kryptonite’s ball joint design. Improving not only on factory components, but even on previous Kryptonite generations. Every aspect of this joint was engineered to survive the demands of lifted trucks, oversized tires, aggressive alignment settings, and real-world abuse.

A massive chromoly stud, powdered-metal races, and a metal-on-metal internal design work together to deliver unmatched strength and articulation. The coil-spring compression system maintains consistent preload throughout suspension travel, reducing looseness and extending service life even under extreme conditions.

Finished with a corrosion-resistant gold zinc cap and protected by a thick rubber boot, the KR6292 is built for longevity, performance, and reliability. Whether you’re daily driving, towing, or pushing your truck off-road, this is a true heavy-duty upgrade over stock and aftermarket alternatives.

Upon install, these ball joints will require 4-6 pumps of grease. Going forward, the recommended service interval is about a half pump every 5,000–7,000 miles. Think of grease like blood in your body: without it, nothing survives. The boots are to keep dust and debris out and not to hold grease in so be careful not to over-grease.

Includes:

• 1 × Kryptonite Bolt-In Upper Ball Joint (KR6292)
• Mounting Hardware Kit
