Overview
The HoBao Hyper 9E Pinion Gear 14T (5mm) H89311 is an essential drivetrain component designed for HoBao 1/8th scale electric RC truggy models. This genuine OEM replacement pinion gear is engineered to deliver reliable performance and maintain the precise gear ratios required for optimal acceleration and top speed in competitive racing environments. Whether you're running a HoBao Hyper Cage Truggy, HoBao Hyper SSTe, or HoBao Hyper SS Brushless RC truggy, this pinion gear is the perfect maintenance item to keep your RC car UK competition-ready.
Pinion gears are critical components in any electric RC car or truck, as they directly interface with the spur gear to transfer power from your brushless motor to the wheels. Over time, even high-quality gears experience wear and tear from aggressive driving, racing, and general use. Having quality replacement pinion gears on hand ensures you can quickly swap worn components and get back to the track. The HoBao 14T pinion gear is precision-manufactured to OEM specifications, guaranteeing perfect mesh with your existing spur gear and maintaining the performance characteristics your RC truggy was built to deliver.
This is the ideal upgrade or replacement part for bashers, racers, and enthusiasts who demand authenticity and reliability from their RC hobby equipment. UK RC enthusiasts choose genuine HoBao parts because they're engineered to the same exacting standards as the vehicles themselves, ensuring perfect compatibility and longevity with your investment.
Key Features

- 14 Teeth Configuration — The 14-tooth design provides an excellent balance between acceleration and top speed, making it suitable for a wide range of track conditions and driving styles from casual bashing to competitive racing.
- 5mm Bore Diameter — The 5mm bore is precisely engineered to fit standard HoBao motor shafts, providing a secure and wobble-free connection that minimises drivetrain loss and maintains consistent performance.
- Genuine OEM Component — As an original equipment manufacturer part, this pinion gear is built to the exact specifications that HoBao engineers designed for their Hyper 9E platform, guaranteeing authentic performance and durability.
- High-Quality Construction — Precision-manufactured from hardened steel, this gear is built to withstand the torque and stress of brushless motors whilst maintaining tooth integrity under racing conditions.
- Easy Installation — The straightforward design and standard 5mm shaft make replacement quick and simple, requiring no special tools or modifications to your RC truggy's motor assembly.
Technical Performance
The HoBao Hyper 9E Pinion Gear 14T operates at Mod 1 pitch, a standard gear module used across HoBao's electric RC truggy range. With 14 teeth, this pinion provides optimal power delivery when meshed with compatible spur gears in the HoBao Hyper system. The 5mm bore diameter matches the shaft specifications of HoBao's brushless motor options, ensuring precise alignment and eliminating backlash that could result in drivetrain inefficiency or premature wear. Constructed from hardened steel, this gear resists the extreme forces generated by modern brushless motors whilst maintaining tooth profile integrity throughout extended racing sessions. The pinion's geometry is engineered to work seamlessly within the transmission of 1/8th scale electric RC truggy models, including the HoBao Hyper Cage Truggy Electric Rolling Chassis, HoBao Hyper SSTe Truggy 1/8th Scale Electric Rolling Chassis, and HoBao Hyper SS Brushless 1/8 Truggy 150A 6S RTR models. Regular inspection and replacement of worn pinion gears is standard practice amongst serious RC racers and bashers, as gear wear directly impacts acceleration response, efficiency, and ultimate top speed achievable on track. UK-based RC car enthusiasts recognise the importance of maintaining genuine component quality to preserve their investment and ensure predictable, reliable performance.

Frequently Asked Questions
- What HoBao RC models is this pinion gear compatible with? — This genuine HoBao part is compatible with the HoBao Hyper Cage Truggy Electric Rolling Chassis (HBCTEB), HoBao Hyper SSTe Truggy 1/8th Scale Electric Rolling Chassis (HBSSTE), and the HoBao Hyper SS Brushless 1/8 Truggy 150A 6S RTR (HB-SSTE-C150RG). Check your model number to confirm compatibility before ordering.
- Why should I replace my pinion gear? — Pinion gears wear over time from the constant meshing with the spur gear and the torque loads generated by brushless motors. Worn teeth can cause poor acceleration response, loss of efficiency, unusual grinding noises, and potential drivetrain damage. Regular replacement is essential maintenance for any serious RC truggy owner in the UK.
- What is Mod 1 gear pitch and why does it matter? — Mod 1 (Module 1) is a standardised gear pitch used across HoBao's electric vehicle range. The modulus determines the tooth profile and size, and using the correct pitch is critical for smooth operation and longevity. Mixing different gear pitches will result in poor mesh, grinding, and rapid wear. Always use Mod 1 gears with your HoBao Hyper 9E platform.
- Is this a genuine HoBao part? — Yes, this is an authentic OEM (Original Equipment Manufacturer) HoBao component, identified by part number H89311 and EAN code 4711605960090. Genuine parts guarantee compatibility, performance, and durability that aftermarket alternatives cannot match.
- Can I use this pinion with other brands of RC cars? — This pinion is specifically engineered for HoBao 1/8th scale electric RC truggy models and is not compatible with other brands. Always verify your vehicle model before ordering to ensure proper fit.
- What is the difference between a 14T and other pinion sizes? — The tooth count directly affects your RC truggy's performance characteristics. Fewer teeth (such as 13T) provide more acceleration but lower top speed, whilst more teeth (such as 15T) deliver higher top speed but slower acceleration. The 14T is a balanced middle-ground suitable for most driving conditions and is the stock specification for many HoBao models.
