The Cognito Alpha Ball Joint for 2011–2025 Chevrolet Silverado and Sierra 2500/3500 trucks is a heavy-duty upper ball joint that uses a bootless scraper-type seal and a zinc-plated housing to resist corrosion. It is rebuildable in the vehicle using a supplied kit with alloy races and a taper pin, allowing maintenance without removing the control arm. The greasable design, alloy internals and oversized sphere provide durability and serviceability for demanding use cases.
