Overview

The ARRMA Spur Gear 65T MOD 0.5: MINI (part number Z-ARA-2660) is a genuine replacement metal spur gear designed specifically for ARRMA 1/16 scale RC vehicles. This is an essential drivetrain component for anyone who owns an ARRMA Mini Kraton 3S or similar 1/16 scale model, whether you're a seasoned RC enthusiast in the UK or discovering the world of RC for the first time. The spur gear is a critical part of your RC car's transmission system, and having a quality replacement on hand ensures you can keep your model running at peak performance.

Built to ARRMA's exacting standards, this metal spur gear features a 65-tooth configuration with a 0.5 MOD tooth profile, making it the perfect direct replacement for factory-fitted gears in compatible ARRMA vehicles. Whether you're bashing around the garden, competing at your local RC club, or simply enjoying casual weekend driving, a worn or damaged spur gear can significantly impact acceleration, top speed and overall drivability. Upgrading to a fresh metal spur gear from ARRMA is one of the smartest maintenance investments you can make for your RC car UK setup.

As an authorised ARRMA retailer, RC Model Shop stocks genuine ARRMA replacement parts and spares, ensuring you always get authentic components engineered to work seamlessly with your model. The metal construction of this spur gear provides superior durability compared to plastic alternatives, making it ideal for drivers who demand reliability and longevity from their RC components.

Key Features

• Metal Construction — Unlike plastic gears that can wear, crack or strip teeth under load, this spur gear is manufactured from durable metal material that withstands extreme driving conditions, whether you're bashing on tarmac, grass or dirt terrain across the UK.
• 65-Tooth Count — The 65T specification is engineered to deliver the optimal balance of acceleration and top speed for ARRMA Mini 1/16 scale models, ensuring your vehicle performs as the manufacturer intended.
• 0.5 MOD Tooth Profile — This modulus specification ensures efficient power transfer from your motor through the drivetrain to the wheels, minimising power loss and maximising responsiveness during acceleration and cornering.
• Genuine ARRMA Component — As an original equipment manufacturer part, this spur gear is engineered to exact tolerances and specifications, guaranteeing perfect fitment and performance with compatible ARRMA vehicles.
• Reliable Drivetrain Performance — A quality spur gear is fundamental to smooth, efficient transmission operation; replacing a worn gear restores acceleration characteristics and reduces drivetrain noise.

Technical Performance

The ARRMA Spur Gear 65T MOD 0.5: MINI represents precision engineering designed specifically for 1/16 scale RC applications. The metal construction provides exceptional durability and longevity compared to plastic alternatives, resisting wear from repeated engagement with the pinion gear and maintaining tooth profile integrity even under high-torque conditions. The 0.5 MOD tooth profile is a critical specification that ensures compatibility with the matching pinion gear in your ARRMA drivetrain, delivering smooth, efficient power transfer with minimal backlash and noise. With a 65-tooth count, this gear is engineered to provide the optimal gearing ratio for ARRMA Mini models, balancing acceleration response with achievable top speed. The metal material resists stripping and tooth damage, making this component ideal for both casual RC enthusiasts and more serious bashers who put significant stress on their drivetrain components during intense driving sessions. Whether you're running 3S LiPo batteries in your Mini Kraton 3S or other compatible ARRMA models, this spur gear is engineered to handle the power delivery reliably and efficiently, maintaining consistent performance over hundreds of driving hours.

Frequently Asked Questions

• Is this spur gear compatible with my ARRMA Mini Kraton 3S? — Yes, the ARRMA Spur Gear 65T MOD 0.5: MINI is specifically engineered as a replacement part for ARRMA 1/16 Mini Kraton 3S models in all colour variants, including the battery and charger included versions. It's the genuine OEM replacement gear for this vehicle platform.
• How do I know if I need to replace my spur gear? — Signs that your spur gear needs replacement include visible tooth wear or damage when you inspect the gear, unusual grinding or clicking noises from the drivetrain during acceleration, reduced acceleration response, or slipping between the pinion and spur gear. A quick visual inspection under good lighting will reveal any wear or damage.
• What is a 0.5 MOD tooth profile and why does it matter? — MOD (modulus) refers to the size and pitch of the gear teeth; 0.5 MOD is the specific tooth profile engineered for ARRMA 1/16 scale models. Using the correct MOD is critical because mismatched tooth profiles will not mesh correctly, leading to poor performance, excessive noise, and premature wear. You must use 0.5 MOD pinion and spur gears together.
• Is this a metal or plastic gear, and which is better? — This is a metal spur gear, which is superior to plastic alternatives because metal resists stripping, maintains tooth profile integrity longer, and handles high-torque applications more reliably. Metal gears are the choice of serious RC enthusiasts who demand durability and consistent performance.
• How often should I replace my spur gear? — Replacement frequency depends on usage intensity. Casual drivers might get hundreds of driving hours from a single gear, while competitive bashers might need replacement every 50-100 hours of use. Regular inspection is the best approach; replace when you notice visible wear or performance degradation.
• Can I use this gear with other ARRMA models? — The ARRMA Spur Gear 65T MOD 0.5: MINI is specifically designed for 1/16 Mini scale ARRMA vehicles. It is not compatible with other ARRMA scales (such as 1/8 or 1/10 models), which use different gear modules and tooth counts. Always verify fitment before purchasing replacement parts.
