2011-2026 Duramax Bolt In Alpha Joint (199-91334)

Fits

Note: Designed specifically for use with Cognito Upper Control Arms.

Ditch the flimsy factory boots and upgrade your Duramax or gas-powered rig with the ultimate heavy-duty upper ball joint. Engineered to bridge the gap between a standard ball joint and a high-performance uni-ball, this Alpha Joint provides the suspension travel and pullout strength needed for leveled or lifted trucks running oversized tires. Its rebuildable, bootless design means you can refresh your front end right on the vehicle, ensuring your steering stays tight and responsive through the harshest conditions.

WARNING: This ball joint is not to be used as a droop limiter and was never designed to support suspension components hanging from the ball joint during operation. Doing so will void any warranty and is an extreme safety risk.
