The Cognito Alpha PRO Ball Joint fits the 2015-2019 GMC Sierra 2500HD and replaces the factory upper ball joint with a patented bootless, greaseable design built for IFS suspension.

Designed for use with Cognito upper control arms.

Install Difficulty: Professional Install Only
Upper ball joint replacement requires a press or ball joint service tool and control arm disassembly, typically takes 2-3 hours per side, and a post-install alignment is required.

Product Overview

This is a heavy-duty upper ball joint that eliminates the traditional dust boot in favor of a scraper-type seal. The result is weather protection without the risk of a torn boot leaking grease.

The internals are alloy steel with alloy races and grease paths, with no plastic liner. A carburized, surface-coated taper pin seats into an oversized sphere for high contact area, strength, and wear resistance on the Sierra 2500HD's IFS front end.

It ships pre-greased with Lithium Complex Grade 2 Grease and includes a top grease fitting for periodic service.
