Frequently Asked Questions
- What ARRMA models is this pinion gear compatible with? — This 17T 48DP pinion gear is designed for the ARRMA Mega 4x4 range and is listed as a standard or optional part for numerous ARRMA 1/10 and 1/8 scale models, including the Granite 4X4 RTR variants, Senton 4X4 RTR variants, Vorteks Boost 2WD models, and Typhon 4X4 RTR variants. If you're unsure whether this part is suitable for your specific model, please check the fitment list or contact our team at RC Model Shop.
- Is this suitable for beginners? — Whilst this is a genuine OEM component, replacing a pinion gear requires basic mechanical knowledge and the ability to safely remove your motor assembly. If you're new to RC car maintenance, we recommend having an experienced RC enthusiast or technician perform the installation to ensure it's done correctly and safely.
- What tooth count should I choose? — The 17-tooth configuration offered here is the specification for the Mega 4x4 platform. Different tooth counts (such as 14T, 15T, 16T, or 18T variants) are available as optional parts if you wish to adjust your vehicle's gearing ratio for different driving characteristics or terrain types, but 17T is the standard OEM specification.
- How often should I replace my pinion gear? — With proper maintenance and care, this tough metal pinion gear should provide reliable service for extended periods. However, if you notice unusual noise from the transmission, visible wear on the teeth, or inconsistent power delivery, it may be time for replacement. Regular inspection during maintenance sessions will help you identify when replacement is needed.
- Will this work with brushless motors? — Yes, this pinion gear is fully compatible with brushless motor conversions on the Mega 4x4 platform. Many RC enthusiasts have successfully used this gear as part of brushless conversion projects, and it pairs perfectly with modern brushless ESCs and high-KV brushless motors.
- What is the bore diameter? — The bore diameter is 3.2mm, which is the standard size for motor shafts used in ARRMA Mega 4x4 models. The included set screw secures the gear firmly to your motor shaft.
