Tamiya SP-1642 TRF420 F 37T Front Direct Pulley - Precision Spare Part  [51642]

37T direct pulley designed for TRF420 drivetrain

The Tamiya TRF420 F Direct Pulley (37T) is a straightforward component intended for TRF420 and TA07 chassis. It aims to streamline the front drivetrain with minimal fuss.

Unified plastic construction reduces mass

This pulley adopts an integrated plastic construction, cutting approximately 2g versus earlier separate-piece models. The simplified design lowers front-end rotating weight and tidies the assembly.

Quick-service screw-mounted cups

Screw-attached direct cups replace the older pin system, allowing cup swaps without dismantling the entire pulley. This reduces workshop time between runs.

Compatibility and practical use

Made for TRF420 and TA07 chassis, the pulley is suited to replacing worn items or upgrading an existing setup. It fits directly to those Tamiya platforms without modification.
