Key Features

• Special Hardened Steel Construction — The pinion is manufactured from hardened steel specifically chosen for its toughness and durability, ensuring that your gear can withstand the demanding forces and stresses of competitive racing, high-speed running, and aggressive terrain. This material selection means your investment will last through countless runs without premature wear or tooth damage.
• CNC-Cut Teeth with Perfect Concentricity — Each tooth is precisely cut using CNC machinery to ensure perfect tooth shape and ultra-true running characteristics. This precision manufacturing eliminates vibration and wobble, resulting in smoother power delivery and more efficient energy transmission from your motor to the wheels.
• Ultra-Precise Tooth Shaping — The teeth are engineered with exacting tolerances to guarantee perfect meshing with your spur gear. This precision fit reduces noise, minimises energy loss, and extends the lifespan of both the pinion and spur gear by distributing forces evenly across the tooth profile.
• Vibration-Free Operation — Thanks to the precise manufacturing tolerances and special gear machine creation process, this pinion delivers smooth, vibration-free running. This translates to better handling characteristics, improved traction, and a more enjoyable RC driving experience whether you're on a circuit or bashing in the garden.
• Easy Identification Marking — Each pinion is clearly marked with the tooth number (15T in this case), allowing for quick and easy identification during maintenance, setup changes, or when you're swapping between different gear ratios at the track.
• Module 32DP Standard — This pinion conforms to the 32DP (32 Diametral Pitch) standard, ensuring compatibility with a huge range of RC cars available in the UK market. 32DP is one of the most common gearing standards for electric RC vehicles, making this a versatile choice for your fleet.
• 3.17mm Motor Shaft Compatibility — The 3.17mm bore diameter is the industry standard for brushless and brushed motor shafts used in 1/10-scale RC cars and similar vehicles, ensuring a secure fit on your motor without any hassle.
• Compact Short Design — The short pinion profile (9mm gear length) is engineered to fit within tight motor housings while maintaining full strength and performance. This compact design is particularly useful for vehicles with limited internal clearance.
• Made in Europe — Corally components are proudly manufactured in Europe to exacting quality standards, giving you the assurance that you're purchasing a genuine, quality product backed by European engineering excellence.
• 1.5mm Hex Key Installation — The pinion secures easily with a standard 1.5mm hex key, making installation, removal, and maintenance straightforward for RC enthusiasts of all skill levels. No special tools are required.

Technical Performance

The Corally 32 DP Pinion represents the pinnacle of precision gear engineering for RC cars. Manufactured using a special gear machine process, this component delivers the kind of technical performance that separates winning RC setups from average ones. The 15-tooth configuration provides an excellent balance between acceleration and top speed, making it ideal for most track conditions and driving styles. The hardened steel construction ensures exceptional wear resistance, meaning this gear will maintain its performance characteristics over hundreds of runs without degradation. With a module of 32DP and a shaft diameter of 3.17mm, this pinion integrates seamlessly with the vast majority of electric RC cars available to UK enthusiasts. The 4mm teeth width and 9mm overall gear length provide a compact yet robust solution for motor pinion replacement or gear ratio optimisation. The precision CNC-cut teeth guarantee that every tooth on this pinion is identical, eliminating the minute imperfections that can cause vibration, noise, and premature wear. When meshed with a compatible spur gear, this pinion will deliver smooth, efficient power transmission with minimal mechanical losses, translating into better acceleration, more consistent lap times, and ultimately, superior performance on the track or trail.

Frequently Asked Questions

• Is the Corally 32 DP Pinion suitable for beginners? — Yes, absolutely. Whilst this is a high-performance component trusted by experienced racers, it is equally suitable for beginners. Pinion gears are basic drivetrain components that simply need to be pressed onto your motor shaft. If you're learning about RC cars and gear ratios, this pinion is an excellent entry point because it's one of the most common 32DP options available. Installation is straightforward with just a 1.5mm hex key required.
• What does the 15T designation mean? — The 15T indicates that this pinion has 15 teeth. The number of teeth on your pinion, combined with the number of teeth on your spur gear, determines your vehicle's gear ratio, which directly affects acceleration and top speed. A 15-tooth pinion is a popular mid-range choice that works well for most RC cars and track conditions.
• Will this pinion fit my RC car? — This pinion will fit any RC car that uses 32DP gearing and has a motor with a 3.17mm shaft diameter. This specification is extremely common in 1/10-scale electric RC vehicles. If you're unsure whether this pinion is compatible with your specific vehicle, check your car's manual or contact us at RC Model Shop for clarification.
• Why choose hardened steel over other materials? — Hardened steel provides superior durability and wear resistance compared to standard steel or composite materials. Because pinion gears experience high rotational forces and constant meshing with the spur gear, the hardened steel construction ensures your pinion will last through countless runs without tooth stripping, cracking, or excessive wear. This makes it an excellent investment for both racing and casual bashing.
• How do I change my gear ratio? — Your overall gear ratio is determined by dividing the number of teeth on your spur gear by the number of teeth on your pinion. For example, if you're running a 15-tooth pinion with a 60-tooth spur gear, your ratio is 4:1. To achieve higher top speed, use a smaller spur gear (lower ratio). To improve acceleration, use a larger spur gear (higher ratio). This pinion allows you to experiment with different ratios to find the perfect setup for your track or driving style.
• What is the difference between the 15T and other tooth counts? — Corally makes this pinion in multiple tooth counts across their range. A 15-tooth pinion is considered a mid-range option; lower tooth counts (like 13T or 14T) provide higher top speed and lower acceleration, whilst higher tooth counts (like 16T or 17T) offer better acceleration and lower top speed. The 15T is versatile and works well for general purpose use, which is why it's one of the most popular configurations.
• Is this pinion suitable for racing? — Absolutely. This pinion is manufactured to competition-grade tolerances and is used by serious RC racers across Europe and the UK. The precision CNC-cut teeth and hardened steel construction ensure that you're getting a component capable of delivering consistent performance run after run, which is essential for competitive racing.
• How do I install this pinion? — Installation is straightforward: loosen your motor's set screw or pinion collar, slide the pinion onto the motor shaft, ensure proper mesh with your spur gear, then tighten the set screw using your 1.5mm hex key. Proper mesh is crucial — there should be a slight amount of free play between the pinion and spur gear. Most RC car instruction manuals provide detailed guidance on pinion installation if you need additional help.
