# Cognito 99-18 Chevy Silverado/GMC Sierra 1500 Alpha Ball Joint for Cognito Upper Control Arms

With a heavy duty design, this is still a joint and thus still a wear item. Being a press in ball joint, you would think it will be a pain to freshen up, but the Alpha Ball Joint is rebuildable and simple to do with a rebuild kit. The ease of rebuilding stems from the corrosion resistant zinc plated housing of the ball joint remaining in the control arm. The ball joint can be rebuilt in the control arm without even having to remove the control arm from the truck. Once the taper pin is removed from the spindle, the top cap of the ball joint is removed followed by all the internal components. The rebuild kit comes with all new internal alloy races, a taper pin, and new scraper seal. Those items are installed with grease, the cap fastened back in place, and then the taper pin re-fastened to the spindle, and that’s it!

-   Bootless seal, protection from weather without risk of torn boots
-   Durability of a ball joint with performance of a uni-ball
-   Greater pullout strength than plastic lined ball joints
-   The ultimate heavy duty upper ball for IFS suspension
-   Greasable, internal grease cavity retains lubricant
-   Alloy joint for maximum longevity, no plastic liner
-   High angle to accomodate more suspension travel
-   Zinc plated corrosion resistant housing
-   Patented (U.S. Pat. 10,731,700)
