The Cognito Alpha PRO Ball Joint fits the 2015-2019 GMC Sierra 3500HD and replaces the factory upper ball joint with a sealed, greaseable, alloy-internal design built for heavy-duty IFS use.

Designed to pair with Cognito upper control arms for maximum suspension travel and longevity.

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

Product Overview

The Alpha PRO uses a bootless scraper-type seal instead of a traditional dust/grease boot, eliminating the most common ball joint failure point on lifted 3500HD trucks.

Internals are alloy steel with alloy races and grease paths -- no plastic liner -- giving it greater pullout strength and the durability of a ball joint with the articulation of a uni-ball.

Pre-greased with Lithium Complex Grade 2 Grease and fitted with a top grease zerk for periodic maintenance. Designed for use with Cognito upper control arms.
