Key Features
- Special Hardened Steel Construction — Manufactured from premium hardened steel, this pinion gear resists wear, stripping, and deformation under high-stress conditions. Hardened steel offers significantly greater durability than standard steel, meaning your pinion will maintain its tooth profile longer and deliver consistent performance across countless RC car sessions without degradation.
- CNC-Cut Teeth with Perfect Concentricity — Every tooth is machined using Computer Numerical Control (CNC) technology, ensuring ultra-precise tooth shaping and perfect concentricity. This precision engineering eliminates runout and vibration, resulting in smooth, quiet operation and reduced stress on your motor bearings and transmission components. Perfect concentricity means the gear spins true without wobble, translating to more efficient power transfer from your motor to the wheels.
- Ultra-Precise Tooth Shaping — The teeth are cut to exacting tolerances on specialised gear-cutting machinery, creating optimal tooth profiles that mesh perfectly with your spur gear. This precision shaping reduces friction, improves mesh efficiency, and minimises the risk of tooth slippage or binding during acceleration and deceleration cycles.
- Vibration-Free Operation — The combination of CNC precision, hardened steel construction, and perfect tooth geometry creates ultra-true running characteristics. This vibration-free operation reduces noise, extends the lifespan of your drivetrain components, and delivers a more refined driving experience—particularly noticeable on high-speed straights where drivetrain noise can otherwise become fatiguing.
- 10-Tooth Configuration — The 10-tooth count provides an aggressive, low-speed gear ratio ideal for applications requiring maximum torque delivery and strong acceleration. This tooth count is perfect for technical courses, soft terrain, and situations where pulling power matters more than top speed. It's a popular choice for crawlers, rocky terrain, and track layouts with tight corners and elevation changes.
- 32 DP Module Standard — The 32 Diametral Pitch (DP) module is a widely recognised standard in the RC hobby, ensuring compatibility with all cars fitted with 32DP spur gears. This universal compatibility means you can freely select your gear ratio by choosing different pinion tooth counts, allowing fine-tuning of your vehicle's performance characteristics.

European manufacturing means consistent quality, precise tolerances, and reliability—factors that distinguish genuine performance components from budget alternatives.
- Comprehensive Gearing Range Available — Team Corally offers this pinion in multiple tooth counts (ranging across the full 32DP range), allowing you to assemble the perfect gear ratio for any track condition, motor power, or driving style. Whether you need more acceleration or higher top speed, there's a Corally pinion to match your requirements.
Technical Performance
The Corally 32 DP Pinion represents precision engineering optimised for performance-oriented RC car enthusiasts. At the heart of this component is hardened steel construction—specifically treated to resist the enormous stresses generated during acceleration, deceleration, and directional changes. When your RC motor's shaft spins, it drives this pinion gear at speeds often exceeding 10,000 RPM, and the pinion teeth must engage with your spur gear hundreds of times per second without slip, wear, or deformation. Hardened steel provides the strength required for this demanding application whilst remaining lightweight enough not to compromise acceleration or motor efficiency.
The 10-tooth configuration delivers a gear ratio specifically suited for applications prioritising torque over top speed. When paired with a 90-tooth spur gear, for example, this creates a 9:1 gear ratio—ideal for technical courses where pulling power through obstacles matters more than outright velocity. The ultra-precise CNC-cut teeth ensure that every engagement with your spur gear is perfectly aligned, eliminating the micro-slippage, chatter, and vibration that plague poorly manufactured pinions. This precision directly translates to better traction control, more predictable handling, and reduced drivetrain strain. The 3.17mm motor shaft diameter specification accommodates a vast range of modern RC motors, including brushless motors from leading manufacturers. The 4.0mm tooth width and 9.0mm overall length represent an optimal balance between contact area and compact design, suitable for both tight OEM motor mounts and custom installations where space is constrained. Build quality is exceptional throughout—the marking system for tooth identification is engraved clearly and permanently, ensuring you never accidentally install the wrong pinion for your setup. For serious RC car UK competitors and weekend bashers alike, this pinion delivers the reliability, precision, and durability expected from genuine Team Corally components.

Frequently Asked Questions
- What is a pinion gear and why do I need it for my RC car? — A pinion gear is a small motorised gear that sits on your motor shaft and drives the larger spur gear fitted to your transmission. The ratio between the pinion tooth count and spur tooth count (the gear ratio) determines how your RC car accelerates and how fast it can go. A 10-tooth pinion delivers strong acceleration and pulling power but lower top speed, making it ideal for technical tracks and terrain where torque matters more than speed.
- What is the difference between a 10-tooth pinion and higher tooth count pinions? — Pinion tooth count directly affects your gear ratio. A 10-tooth pinion paired with a standard 90-tooth spur creates a 9:1 ratio, delivering aggressive acceleration and lower top speed. Higher tooth counts (like 13T or 15T) create higher gear ratios, increasing top speed but reducing acceleration. Lower tooth counts increase torque delivery further. You choose pinion teeth based on your track layout, terrain, and driving style.
- Is the Corally C-71510 pinion compatible with my RC car? — Yes, provided your RC car uses 32DP gearing and has a motor with a 3.17mm shaft diameter. The 32DP standard is widely used across RC buggies, trucks, and off-road vehicles. The 3.17mm shaft is a common motor specification. Check your motor specifications and existing spur gear to confirm compatibility before ordering.
- What makes hardened steel pinions better than standard steel? — Hardened steel is heat-treated to increase its hardness and resistance to deformation. During RC driving, pinion teeth experience enormous forces as they engage with the spur gear thousands of times per second. Standard steel teeth wear down, become rounded, and eventually slip or strip. Hardened steel maintains its tooth profile for far longer, delivering consistent performance across many more RC sessions and ultimately proving more cost-effective over time.
- How often should I replace my pinion gear? — Pinion lifespan depends on driving intensity, track conditions, and maintenance. Inspect your pinion regularly for tooth wear, chipping, or deformation. Smooth, unmarked teeth indicate a healthy pinion. Signs of wear include rounded or flattened tooth profiles, visible scoring, or discolouration. Most RC enthusiasts replace pinions annually during standard maintenance or when noticeable wear becomes evident. A spare pinion is essential for competitive drivers and serious bashers.
- Can I use different tooth count pinions to adjust my RC car's performance? — Absolutely. This is one of the primary reasons to purchase quality pinion gears like this Corally component. By swapping to a lower tooth count (e.g., 9T), you increase torque and acceleration but reduce top speed. Swapping to a higher tooth count (e.g., 12T) increases top speed but reduces acceleration. Experimenting with different pinion tooth counts is an excellent way to fine-tune your RC car's performance for different tracks or driving styles.
- Why is CNC precision important in a pinion gear? — CNC (Computer Numerical Control) machining ensures every tooth is cut to identical specifications with micrometre-level precision. This means perfect concentricity—the gear spins perfectly true without wobble. Inferior pinions cut on manual machines exhibit runout (wobble), causing vibration, noise, and uneven wear on the spur gear. The Corally pinion's CNC precision delivers smooth, quiet, vibration-free operation and extends the lifespan of your entire drivetrain.
- What does 32DP mean, and will this pinion fit my car? — DP stands for Diametral Pitch, a measurement standard for gear sizing. 32DP is a widely adopted standard in RC racing and bashing. If your car uses a 32DP spur gear, this 32DP pinion will fit perfectly. Check your existing spur gear for DP marking, or consult your RC car's manual. Most modern RC buggies, trucks, and crawlers use 32DP or 48DP standards.
- Is this suitable for both competitive racing and casual bashing? — Yes. The Corally C-71510 is suitable for both applications. For competitive racing, precision engineering and reliability are essential—this pinion excels in that environment. For casual bashing on rough terrain, the hardened steel construction withstands the demanding impacts and stress of off-road driving. Whether you're racing at your local club or bashing in your backyard, this pinion delivers the quality and durability needed.
- What motor shafts is this pinion compatible with? — This pinion is designed specifically for 3.17mm motor shaft diameters. This is a standard specification across many brushless and brushed motors from leading manufacturers. Before purchasing, verify that your motor has a 3.17mm shaft. Motors with different shaft diameters (such as 3mm or 2.5mm) will not fit this pinion correctly.
- How do I install this pinion on my motor? — Installation requires a 1.5mm hex key (Allen wrench) to secure the pinion grub screw onto your motor shaft. Slide the pinion onto the shaft, align it with your spur gear to achieve proper mesh (approximately 0.5mm clearance), then tighten the grub screw firmly. Ensure the pinion is positioned flush against the motor's mounting bracket and does not rub on any drivetrain components. Consult your RC car's manual for detailed installation procedures specific to your model.
