Fits

The Cognito Alpha Ball Joint is the top-tier upgrade for press-in style Cognito upper control arms, combining the durability of a heavy-duty ball joint with the performance of a uni-ball. With no boot to rip, a greasable design, and the ability to rebuild it on the truck, this joint is built for long-term performance and easy serviceability.
