Drive train improvements with 3RACING Aluminum Differential Pulley Gear T42

The 3RACING Aluminum Differential Pulley Gear T42, model 3RAC-3PY/42, is a practical upgrade aimed at improving drivetrain efficiency and consistency. It helps smooth power transfer so acceleration and throttle response feel more predictable on both race days and regular practice sessions.

Material and compatibility notes

Made from durable aluminium, this pulley is built to handle repeated running while resisting wear better than many stock plastic parts. It fits a variety of common RC drivetrains, but check spline and diameter details against your vehicle before fitting.

Fitting advice for smooth operation

Before installation, clean mating parts and inspect for wear to ensure proper mesh and alignment. Tighten fasteners to the recommended fitment and redo checks after the first few runs. Routine inspection and light lubrication where appropriate will extend service life.
