The Tamiya 51564 front direct cup set is a replacement pair for the TRF419 front direct-coupling spool. These cups reduce concentrated stress on the front drive train and help the spool rotate more evenly during high speed running.
Made from tough steel, each cup is intended to withstand repeated race use. The construction focuses on preserving part life under regular intense driving.
Swapping the cups is a routine maintenance job and they are designed to fit the TRF419 front coupling without altering the chassis setup. They are a practical spare for keeping a TRF419 race ready.
