Overview
The HoBao St L/Weight Spur (Spider Diff) Gear 52T with Bearing is a precision-engineered replacement spur gear designed specifically for the HoBao Hyper ST Truggy range. Whether you're running an RC truggy for competitive racing or weekend bashing across the UK, this genuine HoBao component delivers the reliability and performance you need to keep your vehicle running at peak efficiency. As a wear-and-tear item that experiences constant stress during driving, having a quality replacement spur gear on hand is essential for any serious RC enthusiast who wants to avoid unexpected downtime.
This lightweight spur gear is engineered for the HoBao Hyper ST Truggy Pro and HoBao Hyper ST Truggy RTR models, making it the perfect replacement when your existing gear shows signs of wear or damage. The integrated bearing design reduces friction and wear on the main shaft, extending the lifespan of your drivetrain components and ensuring smooth power delivery from your motor to the wheels. For anyone running a competitive RC car or looking to maintain their truggy in top condition, this is an investment in reliability and performance.
HoBao is recognised worldwide for producing high-quality RC vehicles and spare parts, and this spur gear exemplifies their commitment to engineering excellence. The 52-tooth configuration is precisely matched to the Hyper ST Truggy platform, ensuring compatibility and optimal gearing for this specific vehicle class. UK RC enthusiasts trust HoBao spares for their durability and accurate fitment, and this component maintains that reputation.
Key Features
- 52-Tooth Spur Gear Design — The 52-tooth configuration is specifically engineered for the HoBao Hyper ST Truggy platform, providing the correct gear ratio for balanced acceleration and top-end performance across a range of driving conditions and terrain types.
- Integrated Bearing — The bearing is built directly into the gear assembly, which reduces friction on the main shaft, minimises wear over time, and contributes to smoother, more efficient power transmission from your motor to the wheels.
- Lightweight Construction — Designated as an L/weight (lightweight) gear, this component reduces rotating mass and unsprung weight on your RC truggy, improving acceleration response and overall handling characteristics.
- Spider Diff Compatible — This gear is specifically designed to work with the spider differential system in HoBao Hyper ST models, ensuring perfect meshing with the pinion gear and differential components for reliable torque distribution.
- Genuine HoBao Component — As an original equipment manufacturer (OEM) part, this spur gear is manufactured to HoBao's exact specifications and quality standards, guaranteeing authentic fitment and performance.
- Easy Replacement — The straightforward design allows for quick removal and installation, minimising downtime and getting your RC car back in action quickly when maintenance is needed.
Technical Performance
The HoBao St L/Weight Spur Gear represents precision engineering at the component level. With 52 teeth, this gear is calibrated to work seamlessly within the drivetrain of the HoBao Hyper ST Truggy platform, delivering consistent torque multiplication from your brushless motor whilst maintaining the speed and acceleration characteristics that these vehicles are designed for. The integrated bearing system is a key engineering feature that separates quality spare parts from basic alternatives—it provides a dedicated rolling-element interface between the gear and the shaft, significantly reducing friction losses and metal-on-metal wear that occurs with standard designs. This means better efficiency, longer component lifespan, and ultimately lower maintenance costs over time. The lightweight designation indicates that HoBao has optimised this gear for minimal rotating mass, which translates to quicker acceleration response and improved weight distribution across your vehicle's chassis. The spider differential compatibility ensures that torque is distributed properly between the wheels during cornering and acceleration, maintaining traction and handling balance. Built from durable materials using HoBao's proven manufacturing processes, this spur gear will withstand the stresses of high-speed running, jumps, and aggressive off-road driving typical of RC truggy use in the UK and beyond.

Frequently Asked Questions
- Is this spur gear compatible with my HoBao Hyper ST model? — Yes, this gear is confirmed compatible with both the HoBao Hyper ST Truggy Pro (HBM7-ST-PRO) and the HoBao Hyper ST Truggy RTR (HBM7-ST). Always verify your exact model before ordering to ensure proper fitment.
- What does the integrated bearing do? — The integrated bearing provides a low-friction rolling interface between the gear and the main shaft, reducing wear, improving power transmission efficiency, and extending the lifespan of both the gear and the shaft itself. This is a premium feature that standard gears do not include.
- When should I replace my spur gear? — You should replace your spur gear when you notice visible tooth damage, chipping, or grinding sounds coming from the transmission during operation. Regular inspection after high-mileage use is recommended to catch wear before catastrophic failure occurs.
- Why is this described as lightweight? — The lightweight (L/weight) designation means HoBao has optimised this gear to minimise rotating mass whilst maintaining durability. Less weight means faster acceleration response and improved overall vehicle handling, which is particularly noticeable in competitive RC racing scenarios.
- Is this an original HoBao part? — Yes, this is a genuine OEM (original equipment manufacturer) part from HoBao, manufactured to their exact specifications and quality standards. Always purchase from authorised retailers to ensure authenticity.
- How does the spider differential work with this gear? — The spider differential is a system that allows wheels to rotate at different speeds whilst maintaining torque distribution during cornering. This 52T spur gear meshes with the differential components to transmit power efficiently in both straight-line and cornering scenarios.

We want to make sure your delivery goes smoothly, so here are some important details about our service:
- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
- Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
