The Tamiya 54023 - RC DB01 37T Front One-Way Pulley is a focused upgrade for belt-driven four-wheel Tamiya cars. It provides a quick way to change front drivetrain behaviour without replacing the whole one-way assembly.
Designed for TRF501X, DB01 and TRF416 chassis, this pulley helps make turn-in smoother and can reduce sudden front traction loss. It is intended to refine handling rather than radically alter setup.
Install the Tamiya 54023 using basic workshop tools and a clean bench. Follow the chassis instructions closely and recheck belt tracking and pulleys after mounting.
