The new 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.
In addition, customers can buy a #91992 complete ball differential kit with caged thrust and #91991 ball differential rebuild with caged thrust bearing. These two new parts are direct replacements for #91702 and #7677, respectively.
