Overview

The HOBAO HYPER EXTREME VTE2 1/7 Motor Pinion Gear 34T MOD1/8MM (H85137) is an essential replacement and upgrade component for owners of the HoBao Extreme VTE2 1/7 on-road electric RC car. This precision-engineered pinion gear is a critical drivetrain component that directly impacts acceleration, top speed and overall performance of your RC car UK setup. Whether you are rebuilding after wear, upgrading your gearing ratio, or setting up a new vehicle, this OEM-specification pinion gear delivers the reliability and performance that competitive RC enthusiasts demand.

Manufactured by HoBao, a recognised leader in high-performance RC vehicles and spare parts, this motor pinion gear is engineered to exacting standards. The 34-tooth configuration with MOD1 spec and 8mm shaft diameter makes it compatible with the VTE2 series drivetrain, ensuring perfect mesh and engagement with your centre spur gear. This is a genuine HoBao spare part, not a clone or counterfeit, guaranteeing authentic fitment and durability.

For serious RC car enthusiasts in the UK looking for ready-to-run RC performance or those building competition setups, having the correct pinion gear specification is absolutely crucial. The wrong gear ratio will compromise acceleration, top speed and efficiency. This genuine HoBao part ensures your 1/7-scale electric on-road RC machine performs exactly as the engineers intended.

Key Features

• 34-Tooth Pinion Gear Configuration — The 34T tooth count is the standard specification for the HoBao VTE2 1/7 on-road electric car, engineered to deliver the optimal balance between acceleration and top-end speed for on-road racing applications.
• MOD1 Gear Module Specification — The MOD1 (Module 1) specification ensures precise tooth geometry that matches perfectly with the 34T centre spur gear fitted to the VTE2 series, guaranteeing smooth engagement and minimal backlash.
• 8mm Shaft Diameter — The 8mm hardened steel shaft diameter is designed to fit the centre spur assembly bore of the VTE2 drivetrain, providing a secure and reliable connection to the transmission system.
• Hardened Steel Construction — This pinion gear is manufactured from hardened steel, offering superior wear resistance, strength and longevity compared to softer materials, critical for the high-stress demands of 1/7-scale on-road racing.
• Genuine OEM HoBao Part — This is an authorised HoBao factory spare part, not an aftermarket alternative, guaranteeing authentic fitment, reliability and compatibility with your VTE2 vehicle.
• Compatible with HB-VTE2-V2 and HB-VTE2-8 Models — This pinion gear fits both the 1/7 Extreme VTE2-V2 on-road electric ARR and the 1/8 Extreme VTE2 on-road electric roller, providing flexibility for multi-vehicle setups.
• Direct Performance Impact — As part of the critical drivetrain system, this pinion gear works in concert with the 34T centre spur to determine your RC car's acceleration curve, top speed capability and overall efficiency on track.

Technical Performance

The HoBao Extreme VTE2 is engineered as a high-performance 1/7-scale on-road electric racing platform featuring a sophisticated 4WD drivetrain system. At the heart of this drivetrain sits the centre spur assembly, which incorporates a hardened steel 34T spur gear fitted to an 8mm shaft. The motor pinion gear (H85137) meshes directly with this centre spur, and the gear ratio between pinion and spur determines your vehicle's performance characteristics. The 34T spur gear is rated to accept pinion gears up to a maximum of 48T, providing tuning flexibility for different track conditions and racing scenarios. The VTE2 features bevel gear-type front and rear differentials filled with precision silicone oils (500K front, 50K rear) to manage power distribution and traction control. The drivetrain utilises hardened steel components throughout, including front universal joint driveshafts and rear dogbone assemblies, engineered to withstand the extreme forces generated by 1/7-scale racing. The motor mounting system uses a CNC-aluminium cam-lock design that accommodates motors up to 50mm OD (with optional provision for 57mm OD motors), allowing installation of high-torque brushless motors essential for competitive on-road racing. This pinion gear, specified in MOD1 with 8mm bore, integrates seamlessly into this precision engineering ecosystem. For UK RC enthusiasts running brushless RC systems, selecting the correct pinion and spur ratio is absolutely critical — too high a ratio sacrifices acceleration, whilst too low sacrifices top speed. The standard 34T pinion works with the 34T spur to establish the baseline gearing, which can be modified through optional 40T ring gear and 15T pinion alternatives for fine-tuning performance to suit your specific racing conditions.

Frequently Asked Questions

• Will this pinion gear fit my HoBao VTE2 RC car? — Yes, this H85137 pinion gear is specifically engineered for HoBao Extreme VTE2 models. It is compatible with both the 1/7 Extreme VTE2-V2 on-road electric ARR (HB-VTE2-V2) and the 1/8 Extreme VTE2 on-road electric roller (HB-VTE2-8). The 34-tooth MOD1 specification with 8mm shaft diameter matches the centre spur assembly bore precisely, ensuring perfect fitment and reliable performance.
• What does MOD1 mean on this pinion gear? — MOD1 stands for Module 1, which defines the tooth geometry and pitch of the gear. It must match the module specification of your centre spur gear to ensure smooth meshing, minimal backlash and efficient power transfer. The VTE2 series uses MOD1 specification throughout its drivetrain, making this pinion gear an exact match.
• Why would I need to replace or upgrade my pinion gear? — Pinion gears wear over time with regular racing and bashing, particularly in competitive environments where high torque and stress are constant. Worn gears cause increased backlash, reduced efficiency and potential drivetrain damage. Additionally, many RC enthusiasts change pinion gear ratios to fine-tune performance for different track layouts, weather conditions or racing strategies. Having quality replacement gears on hand ensures you can maintain peak performance and quickly adapt your setup.
• Can I use a different tooth count pinion gear? — The VTE2 centre spur can accommodate pinion gears ranging from standard up to optional configurations. However, changing the tooth count will directly impact your vehicle's acceleration and top speed characteristics. A lower tooth count (smaller pinion) results in faster acceleration but lower top speed, whilst a higher tooth count increases top speed at the expense of acceleration. Always consult HoBao's optional parts guide and your vehicle manual for approved alternative ratios.
• Is this a genuine HoBao part or a clone? — This is a genuine, authorised OEM HoBao spare part manufactured to factory specifications. We stock only authentic HoBao components to guarantee reliability, fitment and performance. Counterfeit drivetrain parts can cause catastrophic failures during racing, so purchasing genuine components from an authorised retailer is essential.
• What is the difference between this pinion gear and optional alternatives? — The standard 34T pinion creates a balanced gearing ratio with the 34T centre spur. HoBao offers optional 40T ring gears (OP-0146) and 15T pinion gears (OP-0147) for alternative ratio tuning. These alternatives allow you to adjust your vehicle's performance envelope — a 15T pinion would provide significantly faster acceleration but lower top speed, whilst a 40T spur would increase top-end speed. Your choice depends on your specific racing requirements and track layout.
• Do I need any special tools to install this pinion gear? — Installation requires standard RC tools including appropriate hex keys or screwdrivers to access the motor and pinion gear mounting hardware. No specialist tools are required, though having a gear puller can be helpful for safe removal of worn gears. We recommend consulting the HoBao Extreme VTE2 manual for detailed installation instructions and torque specifications.
• Is this suitable for beginners? — This is a component designed for those with some experience in RC car maintenance and drivetrain servicing. It is not intended as a beginner-level product, as understanding gear ratios, proper meshing and installation techniques requires technical knowledge. However, experienced RC enthusiasts, competition racers, and those comfortable performing vehicle maintenance will find this to be an essential spare part.
• What should I do if my pinion gear is damaged? — A damaged or worn pinion gear should be replaced immediately to prevent further drivetrain damage. Continuing to operate with a damaged pinion can cause misalignment, gear slippage and potential breakage of the centre spur or motor output shaft. Always carry spare pinion gears in your pit bag when attending racing events.
