Upgrade Your TRF Chassis with a 37T One-Way Pulley

The Tamiya 3454641 37T one-way pulley is a precision component for TRF series cars, including TRF419 and TRF419X. Designed to let the front wheels overrun one way, it reduces unnecessary drag on straights while remaining strong enough for frequent competitive use. This part is a solid choice for enthusiasts wanting crisper drivetrain response.

Why Choose the 37T One-Way Pulley

Compatibility: Fits Tamiya TRF419, TRF419X, 42301, and 42285 chassis layouts.
Durability: Made to tolerate repeated racing loads.
Performance: Cuts front wheel drag to help preserve momentum.

Does this require other upgrades to work well?

Not necessarily, but pairing it with fresh bearings and a well-tuned diff will make the most of its low-drag design.

Is it suited to off-road surfaces?

It is intended for TRF chassis performance, which is typically on-road; off-road use may expose it to harsh debris so inspect and clean regularly.

Are replacement parts available?

Replacement one-way units and compatible bearings can be sourced from Tamiya parts lists or specialist suppliers if needed.
