Key Features
- Hardened Steel Construction — The pinion gear is machined from durable steel material, which provides superior strength and longevity compared to softer materials, ensuring the gear maintains its tooth profile even under sustained high-torque loads during aggressive driving.
- 32-Pitch Specification — The 32-pitch (32P) diameter ensures compatibility with standard RC drivetrain systems and allows precise meshing with 32-pitch spur gears, delivering efficient power transfer with minimal backlash and wear.
- 13-Tooth Configuration — The 13-tooth count strikes an optimal balance between acceleration and top speed, making this pinion suitable for both crawler applications requiring low-end torque and faster-paced driving scenarios demanding responsive throttle control.
- 5mm Motor Shaft Compatibility — The 5mm bore is engineered to fit standard brushless motor shafts found in many RC vehicles, ensuring a secure and precise fit that eliminates wobbling or slippage during operation.
- Precision Engineering — Each gear is manufactured to exacting tolerances, ensuring smooth, quiet operation and reliable power delivery with minimal vibration and drivetrain noise.
- Genuine Axial Option Part — As an official Axial component, this pinion gear is designed and tested to work seamlessly with the full range of Axial RC models and upgrade kits, backed by manufacturer quality standards.
- Replacement and Upgrade Ready — Whether you're replacing a worn pinion or upgrading an existing setup, this gear integrates directly into your existing RC drivetrain without additional modifications required.

Frequently Asked Questions
- What is a pinion gear and why do I need one? — A pinion gear is a small toothed wheel that sits on your motor shaft and drives the larger spur gear in your RC vehicle's transmission. It directly transfers power from your brushless motor to the drivetrain, making it critical for performance. Upgrading to a quality steel pinion like this one improves durability and power transfer efficiency, particularly if you're running a high-KV motor or pushing your RC car UK setup hard.
- Will this pinion gear fit my RC vehicle? — This pinion will fit any RC vehicle with a 5mm motor shaft and 32-pitch drivetrain system. Common compatible models include various Axial crawlers, monster trucks and scale rigs. Check your vehicle's specifications or contact our team at RC Model Shop to confirm compatibility with your specific model before purchasing.
- How long will a steel pinion gear last? — Steel pinion gears are significantly more durable than plastic alternatives and will typically last multiple seasons of regular driving when properly maintained. Lifespan depends on driving intensity, terrain difficulty and maintenance practices. Inspecting the gear regularly for wear and ensuring proper mesh with your spur gear will maximise service life.
- What is the difference between 13T and other tooth counts? — Tooth count directly affects your vehicle's speed and acceleration characteristics. A 13T pinion provides balanced performance with good acceleration and respectable top speed. Lower tooth counts (12T) favour top speed at the cost of acceleration, whilst higher counts (15T) provide stronger acceleration but lower maximum speed. Choose based on your driving style and terrain.
- Can I use this with any brushless motor? — This pinion is designed for any brushless motor with a standard 5mm shaft. It will work with various KV ratings, though higher-KV motors will produce greater top speed when paired with this 13-tooth pinion. Ensure your ESC and battery system can handle the power demands of your chosen motor configuration.
- Do I need tools to install this? — Installation typically requires basic RC tools such as a small hex driver or motor tool to remove your old pinion and secure the new one. If your vehicle uses a set-screw retention system, you may benefit from using threadlocker to prevent the pinion from loosening during driving.
