HOBAO Hyper GTB Nitro 2-Speed Spur Gear 20T/24T HOP-0043

Overview

The HOBAO HYPER GTB NITRO 2-SPEED SPUR GEAR 20T/24T (HOP-0043) is an essential performance upgrade component for serious nitro RC enthusiasts in the UK who demand precision engineering and reliable power delivery. This genuine HOBAO OEM part is specifically engineered for the Hyper GTB nitro on-road platform, as well as compatible Hyper GTS and Hyper VT nitro models, making it an ideal choice for anyone looking to optimise their RC car's performance on road surfaces. Whether you're a dedicated racer pushing for competitive lap times or an experienced hobbyist seeking to fine-tune your nitro RC setup, this 2-speed pinion gear represents the quality and precision that HOBAO is recognised for across the global RC community.

The 2-speed pinion gear system is a critical component in nitro-powered RC cars, directly affecting acceleration, top speed, and overall drivetrain efficiency. This particular gear set features dual tooth counts—20 teeth and 24 teeth—allowing you to select the gear ratio that best suits your driving conditions, track layout, and tuning preferences. Ready to run RC cars demand high-quality drivetrain components to maintain consistent performance, and this genuine HOBAO part ensures your Hyper GTB or compatible model operates at peak efficiency. The engineering excellence that goes into every HOBAO product is evident in this precision-machined spur gear, which has been proven on tracks across the UK and beyond.

As a direct replacement or upgrade component for your nitro RC car UK setup, this 2-speed pinion gear is manufactured to exacting tolerances by HOBAO, ensuring perfect mesh with your vehicle's clutch bell and transmission system. The dual-ratio design gives you the flexibility to adapt your car to different racing conditions without requiring complete drivetrain replacement—simply swap between the 20-tooth and 24-tooth configurations depending on your needs. This level of customisation and performance-tuning capability is what sets apart serious RC enthusiasts from casual users, and HOBAO's reputation for quality ensures this component will deliver consistent results season after season.

Key Features

• 2-Speed Design with 20T/24T Ratio Options — This gear features two different tooth counts (20 teeth and 24 teeth) in a single component, giving you the ability to select different gear ratios without purchasing multiple parts. A 20-tooth configuration provides faster acceleration and higher top speed, whilst the 24-tooth option delivers better torque and acceleration characteristics—this flexibility is invaluable for adapting your nitro RC car to different track conditions and weather.
• OEM HOBAO Engineering — This is an official HOBAO part manufactured to the brand's exacting quality standards, ensuring perfect compatibility with Hyper GTB, Hyper GTS, and Hyper VT nitro models. Original equipment manufacturer components maintain the integrity of your drivetrain and ensure your RC car performs exactly as designed by the engineers at HOBAO.
• Precision-Machined Construction — Each gear is machined with precision tolerances to ensure smooth engagement with your clutch bell and transmission, minimising noise, vibration, and power loss during operation. Precise manufacturing directly translates to more efficient power delivery from your nitro engine to the wheels.
• Direct Compatibility with Hyper Nitro Models — This spur gear is specifically engineered for use with HOBAO Hyper GTB, Hyper GTS, and Hyper VT nitro on-road models, guaranteeing perfect fitment and optimal performance without modification or adjustment. No guesswork, no compatibility issues—just reliable performance.
• Dual-Ratio Technology — Rather than being locked into a single gear ratio, you have the flexibility to change between 20-tooth and 24-tooth configurations depending on whether you're chasing top speed on a long track or optimising acceleration for tighter courses. This adaptability means you're not sacrificing performance in any particular area.
• Essential Drivetrain Component — The spur gear is a critical element of your nitro RC car's power transmission system, directly responsible for converting engine torque into wheel rotation. A quality spur gear like this ensures efficient power transfer and consistent performance lap after lap.

Technical Performance

The HOBAO HYPER GTB NITRO 2-SPEED SPUR GEAR represents the engineering excellence that serious RC enthusiasts expect from HOBAO. This precision-machined component is engineered to work seamlessly with the nitro-powered engine and transmission system found in HOBAO's Hyper GTB platform and compatible Hyper GTS and Hyper VT models. The dual tooth-count design (20T/24T) provides you with complete flexibility in tuning your vehicle's power delivery characteristics. In nitro-powered RC cars, the spur gear's tooth count directly determines the gear ratio between your engine and the wheels, fundamentally affecting both acceleration and top speed. A lower tooth count (20T) delivers higher top-end speed and less torque multiplication, making it ideal for high-speed tracks with long straights where you want maximum velocity. Conversely, the higher tooth count (24T) provides increased torque multiplication and faster acceleration, benefiting drivers on technical courses with tight corners and acceleration zones. The precision manufacturing standards employed by HOBAO ensure that tooth engagement is smooth and precise, minimising energy loss and maintaining the efficiency of your drivetrain. This is particularly important in competitive nitro RC racing, where every fraction of a second counts and drivetrain losses directly impact your lap times. The materials used in HOBAO spur gears are selected for durability and performance, capable of withstanding the intense stresses imposed by a high-revving nitro engine whilst maintaining dimensional stability. Whether you're running your Hyper GTB on a UK club circuit or pushing it hard at a competitive event, this spur gear provides the reliable performance platform you need.

Frequently Asked Questions

• Is this spur gear compatible with my HOBAO nitro RC car? — This 2-speed pinion gear is designed specifically for HOBAO Hyper GTB, Hyper GTS, and Hyper VT nitro on-road models. Before purchasing, confirm your vehicle matches one of these models. If you're unsure which model you own, check your vehicle's manual or contact our team at RC Model Shop for clarification.
• What is the difference between the 20-tooth and 24-tooth configurations? — The 20-tooth setting provides a higher gear ratio, delivering greater top speed and reduced torque multiplication, making it ideal for high-speed tracks and maximum velocity runs. The 24-tooth setting lowers the gear ratio, increasing torque multiplication and acceleration response, which is better suited for technical courses with many corners. Your choice depends on your track layout, driving style, and performance priorities.
• How often will I need to replace this spur gear? — With proper maintenance and operation, a quality HOBAO spur gear like this should provide extended service life. However, heavy use, aggressive driving, or maintenance neglect can accelerate wear. Inspect your spur gear regularly for tooth damage or excessive wear, and replace it if you notice loss of performance, noise, or slipping during engagement.
• Will this part improve my RC car's performance? — If you're replacing a worn spur gear, installing a new one will restore lost performance and efficiency. If you're switching between the 20-tooth and 24-tooth ratios to suit different conditions, you can optimise your car's acceleration or top speed characteristics for specific tracks or driving conditions.
• Is specialist installation required? — Installation of this spur gear requires basic mechanical knowledge and tools. Most experienced RC enthusiasts can install it themselves by removing the clutch bell and replacing the gear. If you're unfamiliar with this process, consult your vehicle's manual or seek assistance from an experienced RC technician.
• Why choose genuine HOBAO parts over aftermarket alternatives? — Genuine OEM components are manufactured to the exact specifications and quality standards that your vehicle was engineered around. Aftermarket or clone parts may have dimensional tolerances that cause poor mesh, noise, vibration, or premature failure. Choosing genuine HOBAO parts ensures your nitro RC car performs reliably and maintains its resale value.
