- Long-lasting durability in extreme RC conditions — Engineered to withstand the punishment of aggressive driving, high-speed runs, jumps, and rough terrain, this gear maintains its integrity where cheaper alternatives would fail, protecting your investment in your RC model and keeping you on the track or field rather than in the pits.

Technical Performance
The ARRMA Spur Gear 50T represents the engineering philosophy that defines ARRMA's approach to RC vehicle components: precision, strength and reliability. Built from super-strong hardened steel, this gear is engineered to handle the rigorous demands placed on modern brushless RC vehicles. The precision manufacturing process ensures that each tooth profile matches ARRMA's exacting specifications, creating perfect mesh with compatible pinion gears and eliminating the backlash, noise and efficiency losses that compromise performance. This attention to detail matters when you're trying to extract maximum speed and acceleration from your 6S brushless RC truck, or when you need consistent performance lap after lap in competitive racing. The gear's robust construction protects against the metal fatigue and tooth stripping that can occur when driving aggressively on concrete, gravel, dirt and over jumps. Whether you're running a 1/7 scale FIRETEAM, MOJAVE or KRATON model, or piloting the 1/8 scale KRATON, NOTORIOUS, OUTCAST, TALION or TYPHON, this OEM gear maintains the smooth, efficient power delivery that makes ARRMA vehicles some of the most enjoyable to drive in the UK RC market.

Frequently Asked Questions
- Is the ARRMA Spur Gear 50T suitable as a replacement for my ARRMA RC car? — Yes, this is a genuine OEM ARRMA replacement part specified for a comprehensive range of their popular models. Check the model fitments listed above to confirm compatibility with your specific ARRMA vehicle. If your model is listed, this gear will fit perfectly and maintain the manufacturer's design specifications.
- Why should I buy a genuine ARRMA replacement instead of a cheaper aftermarket gear? — Genuine ARRMA parts are engineered to exact specifications and manufactured to the same quality standards as the gears fitted to new vehicles. Aftermarket alternatives may have inconsistent tooth profiles, softer steel, and poorer durability. Using genuine parts protects your investment in your RC model and ensures reliable performance and longevity.
- How often do I need to replace the spur gear on my ARRMA RC truck? — The lifespan of a spur gear depends on driving intensity, terrain, and maintenance. High-speed running on rough surfaces, aggressive stunting, and lack of lubrication all accelerate wear. Inspect your gear regularly for tooth damage, wear, or chipping. Having spare gears on hand means you can continue driving immediately rather than waiting for replacements, making this an essential consumable part for active RC enthusiasts.
- What tooth count options are available, and does tooth count affect performance? — ARRMA offers spur gears in different tooth counts. The 50T configuration provided here is a proven setup across multiple ARRMA models, balancing acceleration, top speed and torque. Larger tooth counts (higher numbers) provide more top speed but less acceleration, while smaller tooth counts improve acceleration at the cost of maximum speed. This 50T gear represents ARRMA's tested and approved configuration for optimal all-around performance.
- Is this part for beginners or experienced RC enthusiasts? — Gear replacement is a routine maintenance task suitable for any RC enthusiast, from beginners to experienced racers. However, it requires basic mechanical knowledge and the correct tools to remove and install the gear. If you're new to RC maintenance, consider learning the process with guidance from experienced RC modellers or your local RC club before attempting the installation yourself.
- How do I know when my spur gear needs replacing? — Signs of a worn or damaged spur gear include excessive noise from the gearbox, loss of power or acceleration, vibration during operation, or visible damage such as chipped or broken teeth. Regular inspection during maintenance will help you catch problems early and prevent further damage to other drivetrain components.
