For those invested in optimizing the performance of their Tamiya TRF419 series, the Tamiya 54879 Aluminum Front Direct Cups offer a practical upgrade. These aluminum alternatives to the standard steel cups are designed to be part of the Direct Coupling (Spool) system on your 4WD race car, providing significant benefits in terms of weight reduction and response.
Switching to aluminum front direct cups reduces the rotating mass by 2.8 grams per cup compared to their steel counterparts. This reduction not only enhances the linear response of your RC vehicle but also contributes to more agile handling, crucial for competitive racing scenarios.
The kit includes two aluminum direct cups and a swing shaft cap, which features a new material for enhanced durability. These components are compatible with the TRF419, TB Evo.6, and TB Evo.7 chassis, making them a versatile choice for various setups.
