Trimmed Shafts for Better Driveability

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.

Practical Gains for Club and Track Use

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.

Fitting four of these shafts reduces overall shaft mass by 22g compared to the stock 4.2mm-diameter pieces. That lowers the car's rotating mass and can be felt in acceleration.
Gearing changes are not required, but some drivers tweak gear ratios to match the slightly faster throttle response and to optimise lap times for their track. Test before committing to permanent setup changes.
