Cognito 20-24 Chevy/GMC Silverado/Sierra 2500/3500 2WD/4WD Ball Joint Upper Control Arm Kit

The patented Cognito Alpha Ball Joint is the next level, end-all be-all solution of upper ball joints. It eliminates the problematic dust/grease boot by using a durable scraper type seal that is not susceptible to damage that a traditional dust/grease boot is. Although the ball joint is firmly sealed and pre-greased, there is a grease fitting at top for any periodic maintenance needed. With a small internal cavity for grease, the joint does not need much at all. The internals are alloy steel, absent of any plastic liner, with alloy races and grease paths. The carburized and surface coated taper pin is a precise fit, has an oversized sphere in the socket for large contact surface providing excellent strength and wear characteristics.
