Key Features

• Special Hardened Steel Construction — The pinion is manufactured from specially hardened steel that resists wear, deformation and tooth breakage far more effectively than standard materials, ensuring longevity even under demanding racing conditions and repeated high-torque applications on the track.
• CNC Cut Teeth for Perfect Tooth Shape and Concentricity — Every tooth is cut using precision CNC machinery to achieve perfect geometry and alignment, which eliminates mesh noise, reduces vibration, and ensures the pinion runs true without wobbling or creating parasitic drag on your motor shaft.
• Module 32DP Specification — The 32DP (diametral pitch) standard means this pinion is compatible with all RC cars equipped with 32DP spur gears, making it a universal upgrade option for countless popular models across the RC car UK market.
• 17-Tooth Configuration — The 17-tooth count strikes an excellent balance between acceleration and top-end speed, making it versatile enough for different track layouts and driving styles without requiring constant gear changes between events.
• 5.0mm Motor Shaft Compatibility — Designed specifically for motors with 5mm shaft diameter, which is the standard size found on most brushless and brushed motors used in modern RC cars, ensuring a perfect fit without modifications.
• Ultra-Precise Tooth Shaping — Team Corally's manufacturing process creates teeth with exceptional precision, which translates to smoother mesh with the spur gear, reduced friction losses, and more efficient power delivery to the wheels.
• Ultra-True Running for Vibration-Free Operation — The concentricity and balance of this pinion ensure it runs with minimal runout, eliminating vibration that would otherwise disturb your RC car's handling and responsiveness.
• Easy Identification Marking — Each pinion is clearly marked with the tooth number (17T in this case), allowing you to quickly and accurately identify the gear when swapping setups or maintaining your vehicle without confusion or measurement.
• Compact Short Design — The short pinion profile minimises unwanted axial play and maintains precise mesh geometry with your spur gear, contributing to consistent performance and reducing wear on both components.
• 2.0mm Hex Socket for Easy Installation — The pinion is secured with a standard 2.0mm hex key, making installation and removal straightforward with basic RC hobby tools that most enthusiasts already own.

Technical Performance

The Corally C-72517 pinion gear represents serious engineering for hobbyists who understand that drivetrain precision directly impacts RC car performance. Manufactured from special hardened steel and finished using CNC machinery, this 17-tooth pinion delivers the kind of concentricity and tooth geometry that separates casual hobby components from competition-grade equipment. The teeth width of 6.2mm ensures adequate surface contact with your spur gear without introducing unnecessary complexity, while the overall gear length of just 13mm keeps the pinion compact and efficient. With a shaft diameter of 5.0mm—the industry standard for brushless and brushed motors—this pinion integrates seamlessly into your existing RC car setup without requiring motor adaptors or shaft modifications. The 32DP specification is the most common pitch used in modern RC cars across the UK market, making this pinion compatible with an enormous range of vehicles from entry-level ready to run models to high-end race kits. Whether you're running a 2S LiPo-powered casual basher or a competition brushless RC buggy, the Corally pinion's precision engineering ensures smooth, efficient power transmission with minimal vibration and maximum responsiveness. The hardened steel material resists the tooth deformation and wear that compromise standard pinions over time, meaning this component will maintain its performance characteristics across hundreds of cycles of use, making it an economical choice for serious hobbyists who value reliability and longevity.

Frequently Asked Questions

• Is the Corally 32 DP Pinion compatible with my RC car? — The Corally C-72517 is designed for any RC car equipped with 32DP (diametral pitch) gears and a 5mm diameter motor shaft. This is the standard specification found on the vast majority of modern brushless RC cars, buggies, trucks and truggies sold in the UK. Check your vehicle's specifications or contact our team at RC Model Shop if you're uncertain whether this pinion will fit your specific model.
• What are the advantages of hardened steel over standard materials? — Hardened steel resists wear, deformation and tooth breakage far more effectively than softer materials or plastic gears. This means the Corally pinion maintains its precise tooth geometry over extended use, preventing the gradual loss of performance and reliability that occurs as standard pinions wear. For competitive RC racers and frequent bashers, hardened steel is the only practical choice.
• Why is concentricity important in a pinion gear? — A pinion that doesn't run true (isn't concentric) will wobble on the motor shaft, creating vibration that transfers to your chassis and compromises handling precision. It also creates uneven mesh with the spur gear, increasing friction losses and wearing both gears faster. The Corally's CNC-cut design ensures concentricity is perfect, delivering smooth, responsive performance.
• Can I use this pinion as an upgrade to my existing RC car? — Yes, absolutely. If your car currently has a different pinion tooth count but uses the same 32DP specification and 5mm shaft, you can swap this 17-tooth version in to adjust your vehicle's gear ratio. A 17-tooth pinion provides balanced acceleration and top-end speed for most track layouts. Our team at RC Model Shop can advise on which tooth count suits your specific driving style and track conditions.
• How do I install the Corally pinion? — The pinion slides onto your motor shaft and is secured using a 2.0mm hex socket (Allen key). Simply slide it onto the shaft until it reaches the desired position, then tighten the set screw with your hex key. Ensure the pinion runs true before operating your RC car. If you're uncomfortable with installation, our team at RC Model Shop is happy to help.
• What is the difference between 32DP and other pinion specifications? — Diametral pitch (DP) refers to the gear tooth size—higher numbers mean smaller, finer teeth. 32DP is the most common standard for RC cars and provides an excellent balance of strength and precision. Some vehicles use 48DP (smaller teeth for higher precision) or 64DP (even finer). Ensure you match your pinion DP to your vehicle's spur gear DP for proper mesh and performance.
• Will this pinion work with brushed and brushless motors? — Yes. The Corally C-72517 is compatible with any motor featuring a 5mm shaft diameter, whether brushed or brushless. Shaft diameter is the determining factor, not motor type.
