Tamiya 40503 Aluminum 14T Pinion Gear - Track Tuner  [40503]

Track-focused upgrade with Tamiya 40503

The Tamiya 40503 Aluminum Pinion Gear (14T) is a precision-machined upgrade for hobbyists wanting crisper throttle response and smoother power delivery. Made from lightweight aluminum, this pinion helps fine-tune acceleration and top speed balance without adding needless weight.

Engineered for Balanced Drive Feel

The 14-tooth layout is chosen to give a sensible compromise between torque and speed so your car remains controllable on short straights and technical sections alike. This gear is ideal for racers and tune-minded hobbyists seeking predictable drivetrain behaviour.

Robust Yet Light Construction

Crafted from durable aluminum, the Tamiya 40503 keeps rotating mass low while standing up to regular use. That combination maintains agility while resisting wear from repeated runs.

Simple Fit and Wide Compatibility

This pinion is compatible with many Tamiya motor setups and installs easily on standard motor shafts. Check your motor shaft size and spline fit before fitting to ensure correct alignment and reliable operation.
