Frequently Asked Questions
- What ARRMA RC models is this 46T spur gear compatible with? — This spur gear is specifically designed for the ARRMA 1/7 LIMITLESS 8S AVC 4x4 RTR in both colourway variants: the White/Blue street speed version (C-ARA7816T2) and the Red/Black street speed version (C-ARA7816T1). Always verify compatibility with your specific model before purchase to ensure correct fit with your differential.
- When should I replace my RC car's spur gear? — Spur gears should be replaced when you notice increased drivetrain noise, rough acceleration, loss of power transmission efficiency, or visible damage such as stripped or cracked teeth. Regular inspection during maintenance intervals helps identify wear before performance is compromised. Replacement is also common when upgrading drivetrain components or experimenting with different gear ratios to optimise performance.
- What is the difference between spur gear tooth counts for RC cars? — Different tooth counts affect your RC car's acceleration and top speed characteristics. Lower tooth counts (smaller gears) favour acceleration and mid-range torque, whilst higher tooth counts increase top speed but may reduce acceleration. The 46-tooth configuration on this gear provides a balanced setup optimised for the LIMITLESS 8S platform's street speed performance envelope.
- Is this a genuine ARRMA part? — Yes, this is an official ARRMA component manufactured to factory specifications and sold under the genuine part number Z-ARA-2813. Genuine spare parts ensure perfect compatibility with your RC model and maintain the engineering integrity of your vehicle. Always purchase genuine components from authorised retailers to guarantee authenticity and performance.
- Do I need any special tools to install this spur gear? — Installation of spur gears typically requires basic RC maintenance tools including hex keys and screwdrivers. Refer to your LIMITLESS 8S AVC user manual for detailed installation procedures, torque specifications and assembly steps. If you're unfamiliar with drivetrain maintenance, our expert team at RC Model Shop can provide guidance and support.
