Team Associated B6 Caged Thrust Bearing Set - Ball Diff

The Team Associated AS91990 B6 Caged Thrust Bearing Set – Ball Diff is a precise, easy-to-use upgrade for B6-series ball differentials. Its caged design automatically spaces the thrust balls for equal loading, simplifying assembly and supporting consistent differential performance. The thrust balls run on two V-grooved thrust rings to minimise drag and promote a smoother, free-spinning action. AS91990 is a direct replacement for #6573 diff thrust washers and AS6574 5/64" balls.
