The Tamiya 84041 - TRF801XT lightweight universal shaft kit is a focused upgrade that cuts rotating mass on the TRF801XT chassis. By reducing the propeller shaft diameter from 4.2mm to 3.4mm each shaft drops from 35g to 29.5g, producing a 22g total weight saving when all four are fitted and delivering crisper acceleration.
Drivers aiming for improved transient response and easier chassis rotation will benefit from these parts. Combined with suspension tweaks and tyre choice, the lighter shafts help the car change speed and direction with less drag from rotating components.
