Technical Performance
The ARRMA Metal Spur Gear, 50T, 0.8M represents a significant upgrade over standard plastic spur gears found in factory RC setups. The metal construction provides substantially greater durability and wear resistance, meaning your RC car's drivetrain will maintain consistent performance across hundreds of driving hours. The 0.8 modulus specification ensures precise tooth engagement with your pinion gear, which is critical for efficient power transfer from your motor to the wheels. This precision engineering minimises backlash and reduces unwanted noise and vibration during acceleration and deceleration. For RC car enthusiasts in the UK who take their driving seriously, whether competing in organised races or enjoying high-performance weekend bashing sessions, upgrading to a metal spur gear like this one is a logical step in building a more reliable and responsive RC car. The 50-tooth count provides an effective gearing solution for 1/8 scale street bash RC vehicles, balancing the needs of both responsive handling and manageable top speeds. Installation is straightforward for anyone familiar with basic RC car maintenance, and the gear integrates seamlessly into the existing drivetrain of compatible ARRMA models. Regular inspection and maintenance of your spur gear ensures optimal performance and extends the working life of your entire drivetrain assembly.

Frequently Asked Questions
- Which ARRMA RC cars is this metal spur gear compatible with? — This metal spur gear is designed specifically for the ARRMA 1/8 INFRACTION 223S DSC 4X4 RTR Street Bash in all colour variants, including Blue/Red, Teal/Pink and Red/Black models. It is a genuine OEM replacement part that ensures perfect fitment and performance.
- What is the difference between a metal spur gear and the plastic one included with my RC car? — Metal spur gears offer superior durability, strength and resistance to wear compared to plastic alternatives. They maintain their tooth profile longer, resist deformation under load, and deliver more consistent performance over extended use. For serious RC enthusiasts, the upgrade to metal gears is a worthwhile investment that extends drivetrain longevity and improves overall vehicle reliability.
- How often should I replace my spur gear? — The lifespan of your spur gear depends on your driving style, frequency of use and maintenance practices. A quality metal spur gear like this one will last substantially longer than plastic versions. Regular inspection for tooth wear, proper lubrication and correct mesh adjustment with your pinion gear will maximise its working life.
- Is this a genuine ARRMA part? — Yes, the Z-ARA-2646 is an authentic ARRMA spare part manufactured to the brand's exact specifications. Purchasing genuine OEM parts ensures compatibility, reliability and warranty coverage for your RC vehicle.
- What modulus means and why does 0.8M matter? — Modulus refers to the size of the gear teeth. The 0.8M specification means this spur gear is designed to mesh precisely with pinion gears of matching 0.8 modulus specification. Using gears with mismatched modulus ratings results in poor mesh, increased wear, noise and potential drivetrain damage. Always ensure your pinion and spur gears have the same modulus rating.
- Can I use this gear with other RC car brands? — This gear is specifically designed for ARRMA 1/8 scale models with 0.8M modulus drivetrain specifications. Using it with incompatible vehicles or gears of different modulus ratings is not recommended and may result in poor performance or damage to your RC car's drivetrain.
