Overview
The HOBAO HYPER GTB NITRO 2-SPEED SPUR GEAR 19T/23T (HOP-0042) is an essential upgrade and replacement component for nitro-powered 1/10 scale RC cars, specifically designed for the HoBao GTB and GTS model ranges. This precision-engineered spur gear set represents a critical upgrade path for UK RC enthusiasts looking to optimise their nitro RC car performance and reliability. Whether you're a competitive racer fine-tuning your machine for maximum efficiency, or a dedicated hobbyist seeking to maintain your existing nitro RC car, this dual-tooth spur gear option provides the flexibility and performance adjustments needed to extract the best from your HoBao platform.
As a key component in the transmission system of high-performance nitro RC vehicles, spur gears are fundamental to how your RC car accelerates, maintains top speed, and delivers power from the engine to the wheels. The 19T/23T configuration offers drivers the choice between two different gear ratios, allowing you to select the setup that best suits your driving style, track conditions, and performance goals. For serious RC car enthusiasts in the UK seeking genuine HoBao parts and accessories, this spur gear set is the authentic choice, manufactured to the exact specifications required by HoBao's engineering team.
This is a genuine HoBao component, not a third-party alternative, which means you're investing in parts designed specifically to work seamlessly with your HoBao Hyper GTB or GTS nitro RC car. Proper spur gear selection and maintenance is crucial for anyone running a nitro-powered RC vehicle, as worn or damaged spur gears will compromise acceleration, speed consistency, and overall drivetrain efficiency. Whether you need a replacement due to wear and tear, or you're looking to experiment with different performance characteristics on your ready-to-run RC car, the HOP-0042 gives you professional-grade options.
Key Features
- Dual Gear Ratio Options (19T and 23T) — This spur gear set provides two different tooth count options, allowing you to select between 19-tooth and 23-tooth configurations depending on your performance requirements. A higher tooth count (23T) will provide better acceleration and torque delivery, whilst a lower tooth count (19T) favours top-end speed for racing on open circuits. This flexibility means you can dial in the exact performance characteristics needed for your specific track layout and driving conditions.
- Designed for HoBao GTB and GTS Models — This component is engineered specifically as an option part for the HoBao Hyper GTB and GTS nitro vehicle ranges, ensuring perfect compatibility, precise fitment, and optimal performance integration with these models. Using genuine manufacturer-approved parts guarantees that the gear ratios, tolerances, and materials meet HoBao's engineering standards.
- Precision Engineering for Nitro Performance — The spur gear is manufactured to exact tolerances required for high-RPM nitro engine applications, where precision and durability are critical. Properly machined gears ensure smooth power delivery, minimal vibration, and consistent acceleration across the entire performance band of your nitro RC car.
- Direct Replacement and Upgrade Path — Whether you're replacing worn factory gears or upgrading from the stock configuration, the HOP-0042 serves as both a maintenance part and a performance tuning component. This makes it essential for any UK RC enthusiast who runs HoBao nitro vehicles regularly.
- Genuine HoBao Manufacturing — As an official HoBao part (model number HOP-0042), this component carries the authenticity and quality assurance of the manufacturer, not a third-party clone or inferior alternative. This ensures longevity, reliability, and proper engagement with your existing drivetrain components.
Technical Performance
The HOBAO HYPER GTB NITRO 2-SPEED SPUR GEAR set represents the precise engineering required to optimise drivetrain performance in competitive and recreational nitro-powered 1/10 scale RC cars. Spur gears are the primary interface between your nitro engine's power output and the wheels, making gear selection absolutely critical to performance tuning. The 19-tooth configuration delivers higher top-end speed suitable for racing on larger circuits and high-grip surfaces, whilst the 23-tooth option provides increased acceleration and torque delivery, making it ideal for tight technical tracks, acceleration-focused racing, or casual bashin where low-end punch is more important than maximum velocity. The 2-speed designation refers to the vehicle's transmission system, which allows drivers to transition between different gear ratios during a race for optimised performance throughout varying track conditions and speed ranges. For serious competitors in the UK RC racing scene, spur gear selection can make the difference between a competitive lap time and simply not staying up with the field. These precision-engineered gears are manufactured to maintain proper mesh with the pinion gear driven by your nitro engine, ensuring smooth power transmission with minimal noise, vibration, or energy loss. Quality control during manufacture ensures that gear tooth profile, pitch, and concentricity meet HoBao's exacting standards, which is essential when running high-revving nitro engines that demand absolute reliability and precision engineering.

Frequently Asked Questions
- What is the difference between the 19T and 23T spur gear options? — The tooth count directly affects your vehicle's performance characteristics. The 19-tooth gear is optimised for maximum top-end speed and is best suited to larger racing circuits where high-speed runs are beneficial. The 23-tooth gear prioritises acceleration and torque delivery, making it ideal for tight technical tracks, autocross courses, or casual bashing where quick acceleration matters more than top speed. Many UK RC racers will have both available and switch between them depending on the track layout and weather conditions.
- Is this spur gear suitable for my HoBao nitro RC car? — The HOP-0042 is specifically engineered for HoBao Hyper GTB and GTS model ranges. If you own either of these models and run them with nitro power, this is the genuine manufacturer component designed for your vehicle. Always verify your specific model before ordering to ensure compatibility.
- How often do spur gears need replacing? — Spur gear wear depends heavily on your driving style, track conditions, and maintenance routine. Aggressive racing, sand, dust, and poor lubrication accelerate wear significantly. Most competitive racers inspect their spur gears regularly and replace them when tooth wear becomes visible or when performance starts to suffer. Casual drivers might extend intervals considerably. Regular inspection is recommended, and having spare gears on hand ensures you're never caught without a critical component at race day.
- Can I use this gear with other HoBao models? — This part is specifically designed for the HoBao Hyper GTB and GTS models. Other HoBao vehicles may require different spur gear specifications. Always verify compatibility with your vehicle's documentation or contact a specialist UK RC retailer before purchasing parts for alternative models.
- What maintenance do spur gears require? — Proper lubrication is essential for spur gear longevity and performance. Ensure your gear mesh is properly oiled with differential or gear oil appropriate for nitro vehicles. Check alignment and wear regularly, especially if you notice any grinding sounds, vibration, or performance loss during acceleration. Keep gears clean and free from sand, dust, and debris, which accelerate wear dramatically.
