This caged thrust bearing set for ball differentials is a precise and easy-to-use upgrade for Team Associated ball differentials. The caged thrust bearing simplifies assembly, automatically spacing the thrust balls for equal loading. The thrust balls run on two V-grooved thrust rings for minimal drag.
#91990 is a direct replacement for #6573 diff thrust washers and #6574 5/64″ balls.
Fits B6.3D, B6.2D, B6.1D, B6D, and older ball differential models.
