The Cognito Alpha PRO Ball Joint fits the 2020-2025 GMC Sierra 2500HD and replaces the factory upper ball joint with a bootless, alloy-internal design built for IFS suspension abuse.

Designed for use with Cognito upper control arms.

Install Difficulty: Professional Install Only
Pressing the ball joint into the upper control arm requires a ball joint press and suspension disassembly; typically takes 2-3 hours per side. Professional alignment required after installation.

Product Overview

This patented upper ball joint (U.S. Pat. 10,731,700) ditches the failure-prone dust boot for a scraper-type seal that resists tearing and contamination.

Internals are alloy steel with alloy races and grease paths, no plastic liner, for greater pullout strength and longer service life than OE-style joints.

The carburized, surface-coated taper pin runs an oversized sphere for a large contact patch, and a top grease fitting allows periodic service of the small internal grease cavity.
