The Cognito Alpha PRO Ball Joint fits the 2020-2025 GMC Sierra 3500HD and replaces the factory upper ball joint with a heavy-duty, bootless design built for IFS suspension.

Designed for use with Cognito upper control arms.

Install Difficulty: Professional Install Only
Pressing the ball joint into the Cognito upper control arm requires a shop press and proper tooling; typically takes 1-2 hours per side. Professional alignment recommended after any suspension modification.

Product Overview

The Alpha PRO uses a scraper-type seal in place of a traditional dust/grease boot, eliminating the most common failure point on lifted HD trucks.

Internals are all alloy steel with no plastic liner, an oversized sphere in the socket, and a carburized, surface-coated taper pin for greater pullout strength and wear resistance.

A grease fitting at the top feeds a small internal cavity for easy periodic maintenance, and the zinc-plated housing resists corrosion.
