Improve Drivetrain Flow with the 37T One-Way Pulley

The Tamiya 3454641 37T one-way pulley is made for the TRF family, such as TRF419 and TRF419X, to refine drivetrain behaviour. It allows the front wheels to freewheel in one direction to lower mechanical drag during fast straights, and its robust manufacturing holds up to frequent track sessions. A practical upgrade for tuners focused on clean power transfer.

Notable Points for the 37T One-Way Pulley

Compatibility: Intended for use with Tamiya TRF419, TRF419X, 42301, and 42285 models.
Durability: Built to resist wear from regular competitive use.
Performance: Reduces front wheel drag to boost drivetrain efficiency.

Can I use standard bearings with this pulley?

Yes, standard-sized bearings that match the original pulley specs will work; ensure they are clean and lightly greased for best performance.

Will it affect front traction?

The pulley reduces rotational resistance, which can slightly alter front-end feel; tuning droop and toe can help retain desired traction.

What lubrication is recommended?

Use a light synthetic oil or silicone-based grease suited to one-way units; avoid heavy greases that increase drag.
