Refining drivetrain behaviour with the 3RACING Aluminum Differential Pulley Gear T42

The 3RACING Aluminum Differential Pulley Gear T42, reference 3RAC-3PY/42, offers a straightforward way to tidy up power transfer in your RC car. It is intended to stabilise torque delivery and reduce erratic driveline response during spirited running.

Build quality and fitment guidance

Constructed from resilient aluminium, this pulley resists deformation and stands up to frequent runs. Its design allows it to mate with many mainstream differentials, though matching spline and bore sizes is important for a secure installation.

Simple installation pointers

Keep all parts free of grime before fitting and ensure the pulley seats squarely on the shaft. Check for side play and confirm gear engagement after a short test run. Basic cleaning and periodic checks will keep performance steady.
