Check your model's documentation or contact our team to confirm compatibility with your specific RC car UK setup, as various ARRMA models utilise this transmission platform.
- Why would I need to replace the main input gear? — The main input gear experiences constant engagement during driving and can wear over time with heavy use. Replacing it maintains smooth power delivery and prevents gear slippage or damage to adjacent transmission components. It's also a common upgrade component for those tuning their RC car's performance characteristics.
- Is this a genuine ARRMA part? — Yes, the Z-ARA311016 is the official ARRMA part number for this main input gear, guaranteeing it meets factory specifications and will provide perfect compatibility with your ARRMA vehicle's GP5 transmission.
- How difficult is it to install the main input gear? — Main input gear replacement requires access to your RC car's transmission and typically involves removing the gear cover and extracting the worn gear. This is a moderate-level maintenance task that many RC enthusiasts handle themselves, though if you're unfamiliar with transmission work, our team at RC Model Shop can advise on the process.
- Will this gear improve my RC car's performance? — The main input gear itself doesn't improve performance if your existing gear is functioning properly, but replacing a worn gear restores your vehicle to factory performance levels. Enthusiasts sometimes experiment with different tooth counts to adjust acceleration versus top speed, but this 15T configuration is the standard specification.
