Tamiya 54934 TRF420 Steel Front Direct Cups Set (2pcs) OP-1934 Tough Front Upgrade  [54934]

Durable Steel Direct Cups for TRF420 Chassis

The Tamiya 54934 Steel Front Direct Cups replace the aluminium front cups on the TRF420 to provide stronger components and additional front mass. These parts are intended for modelers wanting a sturdier front end and alternative balance options.

Performance and Handling Advantages

Steel cups improve impact tolerance and add weight to the front, which can help stabilise the car and broaden setup choices for different circuits. They are a practical way to influence understeer and front-end grip without major modifications.

Which Models Are Compatible

These steel direct cups are made for the TRF420 and any models that use the TRF420 Front Direct Pulley (37T). They install directly and are useful when you want to experiment with front weight for different driving conditions.
