Technical Performance
The centre differential top plate is a precision-machined component that plays a vital role in your HoBao Hyper RC buggy or truggy's mechanical performance. By controlling how power is distributed between the front and rear axles during acceleration and cornering, the differential top plate directly influences handling balance, traction characteristics and overall driving experience. The integrated air filter holder design reflects HoBao's commitment to smart engineering — rather than requiring separate components, this unified design reduces assembly complexity whilst maintaining the airflow pathway essential for cooling nitro engines or maintaining proper air intake function on electric variants. The component's robust construction ensures it withstands the stresses of competitive racing, weekend bashing, and the demands of high-performance driving on UK circuits and outdoor terrain. By keeping this part in factory-original specification, you preserve the carefully engineered balance that HoBao's development team has tuned into the Hyper platform.

Check the model list above to confirm your specific RC buggy or truggy uses this component.
- Why should I replace the centre differential top plate on my HoBao Hyper? — Over time and with frequent use, the centre differential top plate can wear, strip threads, or become damaged, affecting the seal integrity of your differential assembly and potentially causing oil leakage or inconsistent handling. Replacing it restores the precise tolerances HoBao engineered into your RC buggy or truggy, ensuring optimal power distribution and predictable cornering behaviour during racing or high-speed runs.
- Is this a genuine HoBao part? — Yes, this is the official OEM part number H90012 sourced directly from HoBao USA. Genuine OEM components ensure perfect fit, finish and function without the compatibility risks that come with aftermarket alternatives. When you replace worn parts with genuine HoBao spares, you're maintaining your RC car to factory standards.
- How do I install the centre differential top plate? — Installation requires basic RC car maintenance skills and standard tools including hex wrenches. Most RC enthusiasts can complete the replacement as part of routine differential servicing. We recommend consulting your HoBao Hyper user manual for step-by-step instructions specific to your model. If you're unsure, our team at RC Model Shop can provide guidance.
- What is an air filter holder and why does it matter? — The air filter holder integrates with this top plate to direct airflow towards your engine's air intake, ensuring proper cooling and preventing dust and debris from entering the combustion chamber on nitro models or affecting the electronic components on electric variants. A well-maintained air filter holder keeps your RC buggy or truggy running smoothly and protects your engine investment.
