Lightweight Prop Shaft Upgrade for Tamiya 84040 - TRF801XT

The Tamiya 84040 - TRF801XT Lightweight Universal Propeller Shaft shrinks the shaft diameter from 4.2mm to 3.4mm to save weight while keeping the chassis balance intact. The near 10 gram weight drop translates to livelier handling and more agile direction changes on course.

Engineered for Tight Handling and Easy Fitment

Targeted at serious hobbyists, this shaft provides lower rotating mass so the model responds faster under throttle and brake. Fitment follows the original mounting points, so the swap is straightforward for routine upgrades.

Specifications

Front Shaft Weight: 24g
Rear Shaft Weight: 27g
Diameter: Reduced from 4.2mm to 3.4mm

Will the thinner shaft affect durability on rough tracks?

The shaft reduces mass but is engineered for racing loads. On very rough or high-impact surfaces inspect it regularly and replace if you see wear or distortion.

Do I need different bearings when fitting this shaft?

Standard bearings for the TRF801XT are compatible. Ensure bearings are in good condition to prevent side play on the slimmer diameter.

How much weight does this save compared to stock?

Compared to the standard shaft, the change from 4.2mm to 3.4mm yields almost a 10 gram reduction in total rotating assembly weight.
