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.
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.
