• Ultra-Precise Tooth Shaping — The teeth are shaped with ultra-precise tolerances using specialised gear-cutting machines, ensuring consistent engagement with your spur gear across every rotation and maintaining perfect mesh alignment even under extreme load.
• Vibration-Free Operation — The combination of CNC precision and hardened steel delivers ultra-true running characteristics, virtually eliminating vibration that can damage other drivetrain components and ensuring smooth, controlled acceleration and deceleration in all driving conditions.
• 48 DP Module Standard — Compatible with all cars designed for 48 DP gearing systems, this pinion integrates seamlessly into your existing RC setup without modification, making it an easy replacement or upgrade option.
• Compatible with 3.17mm Motor Shafts — The 3.17mm shaft diameter accommodates standard brushless and brushed motors with this shaft size, ensuring a secure fit and reliable power transmission from your motor to the drivetrain.
• Easy Identification System — Each pinion is clearly marked with the tooth number, allowing you to quickly and accurately identify the correct gear for your setup, eliminating confusion and ensuring you select the right ratio for your car.
• 17-Tooth Configuration — The 17-tooth design provides a specific gear ratio that balances speed and acceleration, making it suitable for a variety of track conditions and driving styles when paired with the appropriate spur gear size.
• Made in Europe — Manufactured in Europe using world-class engineering standards and quality control processes, ensuring that every pinion meets the exacting requirements of professional racers and serious RC enthusiasts.
• Compact Short Design — The short pinion design minimises weight whilst maintaining structural integrity, reducing unsprung mass on your motor and improving overall vehicle handling and responsiveness.

Technical Performance

The Corally 48 DP Pinion C-71417 represents the highest standard in precision drivetrain engineering for RC cars throughout the UK and beyond. With its 17-tooth configuration and special hardened steel composition, this pinion delivers exceptional durability whilst maintaining the concentricity and precision required for high-performance operation. The gear measures 9.0mm in length with a tooth width of 4.0mm, optimising the contact area between the pinion and spur gear for maximum load distribution and longevity. The 3.17mm shaft diameter fits standard brushless and brushed motors, making this pinion compatible with a vast range of modern RC vehicles. The hexagonal socket accepts a 1.5mm hex key for straightforward installation and removal, allowing quick gear ratio changes when you need to adapt your setup for different track layouts or driving conditions. Manufactured using CNC machining rather than traditional hobbing methods, the teeth feature ultra-precise shaping that eliminates the micro-imperfections found in lower-quality gears, resulting in smoother power delivery, reduced drivetrain noise, and improved efficiency that translates into better lap times and improved handling characteristics. The hardening process increases the material's resistance to the crushing forces generated during acceleration and the shearing forces created during cornering, extending the working life of the pinion far beyond standard steel alternatives. When you select a 17-tooth pinion for your 48 DP setup, you're choosing a gear ratio that provides balanced performance across most track conditions, delivering adequate top speed whilst maintaining strong acceleration and responsive handling.

Frequently Asked Questions

• What is the difference between 48 DP pinion gears and other module sizes? — The 48 DP (diametral pitch) specification determines the size and spacing of the teeth on the pinion gear. A 48 DP pinion has smaller teeth spaced more closely together than lower DP ratings such as 32 DP, making it suitable for smaller RC cars and providing finer control over gear ratio selection. The DP rating must match your spur gear and motor pinion bore diameter, so always verify compatibility before purchasing.
• Is the Corally C-71417 pinion suitable for beginners? — Yes, this pinion is suitable for any RC enthusiast regardless of experience level. Whether you're a beginner discovering the world of RC for the first time or a seasoned competitor, this is a standard replacement component that works with any 48 DP equipped RC car. However, you should ensure your vehicle is designed for 48 DP gears before ordering, as it won't fit gearboxes designed for other module sizes.
• What motor shaft size does this pinion require? — The C-71417 is specifically designed for motors with a 3.17mm shaft diameter, which is the standard size found on most modern brushless and brushed RC motors. Always verify your motor's shaft diameter before purchasing, as pinions with different shaft diameters will not fit correctly.
• How do I select the correct tooth count for my setup? — The tooth count you select depends on your desired gear ratio, which in turn affects your vehicle's speed and acceleration characteristics. A higher tooth count (such as 19T or 21T) creates a lower gear ratio, increasing top speed but reducing acceleration. A lower tooth count (such as 15T or 17T) creates a higher gear ratio, reducing top speed but improving acceleration and torque. The 17-tooth configuration provides a balanced middle ground suitable for most track conditions. Consult your RC car's manual or contact RC Model Shop for recommendations based on your specific vehicle and intended use.
• What is special about the hardened steel construction? — The hardening process increases the material's hardness and strength, making the pinion more resistant to wear, tooth breakage, and deformation under load. Hardened steel pinions last significantly longer than standard steel alternatives, making them an excellent choice for competitive racing and regular bashing. The cost difference is minimal compared to the extended lifespan and improved reliability you'll experience.
• How do I install this pinion on my RC car? — Installation varies depending on your specific RC car model, but generally involves removing the motor from the gearbox, sliding the old pinion off the motor shaft, sliding the new pinion on, and securing it with the set screw using a 1.5mm hex key. Always consult your vehicle's manual for specific instructions, and ensure the pinion is seated properly on the shaft before tightening the set screw.
• Can I use this pinion with any 48 DP spur gear? — Yes, the C-71417 will mesh with any 48 DP spur gear, allowing you to create virtually any gear ratio you desire by selecting different spur gear tooth counts. However, ensure the spur gear is of similar quality and condition to avoid excessive wear and mesh problems.
• Is this pinion compatible with both brushless and brushed motors? — Yes, the C-71417 works with any motor (brushless or brushed) featuring a 3.17mm shaft diameter. The pinion is agnostic to motor type, so you can upgrade or change your motor without needing a different pinion, provided the shaft diameter remains 3.17mm.
