Drivetrain smoothness upgrade with Tamiya 37T pulley

The Tamiya 42310 37T aluminum differential pulley replaces the stock plastic gear in many belt-driven Tamiya models. With an HL coating for extra lubrication, it promotes smoother power delivery and adds durability for track use or regular club racing.

Fitment and chassis details

This pulley is made to fit TRF419, TRF419X and TA07 chassis, and it also supports models that use Item 51568 such as TRF418, TRF417, TA05 and TRF501. It is a direct replacement for worn plastic pulleys and suits racers wanting a more consistent drivetrain feel.

The HL coating acts as a low-friction surface layer, helping the pulley turn with less resistance. That results in smoother torque transfer and can reduce minor oil seepage around the differential area.
Yes, it is designed for TRF419, TRF419X and TA07 series. It is also compatible with models using Item 51568, including TRF418, TRF417, TA05 and TRF501, so no custom machining is required for those applications.
Check belt alignment and tension when fitting the aluminum pulley, use the original mounting hardware, and keep the differential area free of grit. Periodic inspection will help maintain smooth operation.
