The Yokomo YZ-501GS Steel Drive Cup set is made to serve the YZ-870C gear differential, providing a stronger option for enthusiastic bashing and competition. This pair helps cut down on wear and keeps your drivetrain running cleaner for longer.
Produced from durable steel, the YZ-501GS cups give greater resistance to wear and impact compared with softer stock pieces. They hold up well under heavy acceleration and rough terrain while preserving accurate power transfer.
These drive cups are contoured to match the YZ-870C differential geometry for straightforward installation. Fit them as a direct replacement or as part of a durability-focused upgrade package.
