This RC-scale replacement drive cup is intended for the High Performance Front One Way (D-021) family and is supplied as a service item for drift-focused Yokomo packages. It functions as the front one-way driver transmitting differential output into the front drivetrain and is meant for use on the DP-series RC drift platforms listed below.
Installation notes: remove the front one-way assembly according to your chassis manual, examine shafts and bearings for wear, then install the D-023A drive cup ensuring correct alignment and any chassis-specified preload. Regular checks for wear and correct seating will support consistent front engagement during drifting. This description treats the item strictly as an RC accessory and does not imply any real-vehicle application.
