2001-2026 Duramax HD Bolt-On Upper Ball Joint (AX6292)

The AX6292 was built with one goal: the strongest bolt-on upper ball joint you can put on a GM truck. A Grade 12.9 Extreme-Duty ball stud sits in a forged steel housing with a precision internal bearing assembly and a self-compensating load system that keeps steering tight as the joint wears. It is fully greaseable, high-articulation, and a direct replacement anywhere a K6292-style bolt-on upper ball joint is specified.
