The Tamiya 84041 - TRF801XT low-mass universal shafts are a precision option for trimming rotating weight on the TRF801XT chassis. Shrinking the prop shaft from 4.2mm to 3.4mm lowers each shaft from 35g to 29.5g, for a combined reduction of 22g when all four are used, which can make the car feel more responsive under acceleration.
Racers and dedicated hobbyists adjusting their TRF801XT setups will notice reduced rotational drag and improved transient behaviour. Use these shafts alongside careful suspension and tyre setup to get the most from the change.
