Improve drivetrain response with the Tamiya 37T pulley

The Tamiya 42310 37T aluminium differential pulley is a stronger alternative to the common plastic pulley in belt-driven Tamiya models. Fitted with an HL coating, it reduces internal friction and supports more consistent power delivery for club racing and practice sessions.

Compatibility information and fitting advice

This pulley is compatible with TRF419, TRF419X and TA07 chassis and is also suitable for vehicles using Item 51568, such as TRF418, TRF417, TA05 and TRF501. It is intended as a direct upgrade or replacement for worn plastic pulleys.

Does the HL coating need special care?

No special routine is required. Keep the area clean, avoid abrasive cleaners, and inspect the coating for damage during routine maintenance to preserve its low friction properties.

Which Tamiya models are supported by this part?

It is designed for TRF419, TRF419X and TA07 chassis and will also fit cars using Item 51568, including TRF418, TRF417, TA05 and TRF501, making it a versatile upgrade for many belt-driven models.

Will switching from plastic to aluminium affect durability?

Aluminium generally resists wear better than plastic in high-load sections. The HL coating helps protect moving surfaces, so you can expect improved longevity versus the stock plastic pulley when fitted and maintained correctly.
