Key Features

• Special Hardened Steel Construction — Manufactured from premium hardened steel material, this pinion gear provides exceptional toughness and durability that resists wear, stripping and damage during aggressive driving and racing conditions. Hardened steel gears maintain their precision longer than standard alternatives, making this a cost-effective long-term investment for your RC car.
• CNC-Cut Teeth with Perfect Concentricity — Each tooth is cut using computer numerically controlled machinery to achieve precise tolerances and unparalleled concentricity. This precision engineering ensures that the gear runs true and balanced, delivering smooth power delivery and eliminating vibration that can compromise performance and cause premature wear to other drivetrain components.
• 19-Tooth Configuration — The 19-tooth design offers an excellent mid-range gearing option that suits most driving conditions. This tooth count provides a good balance between acceleration and top speed, making it suitable for a wide variety of track layouts and driving styles.
• 48 DP Module Rating — The 48 diametral pitch (48 DP) specification indicates this pinion is designed for precision mesh with compatible 48 DP spur gears. This ensures proper gear engagement without backlash, delivering efficient power transfer and smooth operation across the entire RPM range of your motor.
• 3.17mm Motor Shaft Compatibility — Designed specifically for motors with 3.17mm diameter shafts, this pinion integrates with the vast majority of modern RC motors used in electric RC cars, buggies and trucks throughout the UK. The precise bore diameter ensures secure, vibration-free mounting.
• Short Profile Design — The short profile of this pinion gear is optimised for space-conscious chassis layouts whilst maintaining full engagement with your spur gear. This design helps reduce overall drivetrain width without compromising power transmission or durability.
• Ultra-True Running — Created on special precision gear machinery, this pinion features ultra-true running characteristics that minimise vibration during operation. Vibration-free operation translates to more predictable handling, reduced noise and less stress on your RC car's bearings and motor shaft.
• Easy Identification Marking — Each pinion is permanently marked with the tooth number, making it incredibly simple to identify which gear you're using at a glance. This feature is invaluable when managing multiple pinions for different gear ratios or when working with other RC enthusiasts.
• Complete Gearing Range Available — Team Corally manufactures this pinion in all standard gearing sizes, allowing you to find the perfect gear ratio for any track layout, motor specification or driving condition. Whether you need a higher-speed ratio or more aggressive acceleration, the complete range ensures compatibility.
• European Manufacturing — Made in Europe to rigorous quality standards, this pinion reflects Team Corally's commitment to precision engineering and attention to detail. European manufacturing means consistent quality control and reliable performance you can depend on.
• 4mm Teeth Width — The 4mm teeth width ensures adequate surface contact with your spur gear whilst maintaining the short overall profile. This dimension is optimised for reliable mesh without excessive drag or inefficiency.
• 9mm Gear Length — The 9mm overall length of the gear is precisely calculated to ensure proper engagement with standard spur gears whilst fitting within typical RC car drivetrain geometries. This dimension allows the pinion to sit correctly on your motor shaft for optimal performance.

Technical Performance

The Corally 48 DP Pinion Short Hardened Steel 19 Teeth represents the pinnacle of precision gear engineering for RC cars, buggies and trucks. Manufactured using CNC machinery from special hardened steel, this component delivers the kind of precision and durability that serious RC car UK racers and hobbyists demand. The 48 DP specification indicates a gear pitch that integrates perfectly with compatible spur gears, ensuring smooth, efficient power transmission with minimal losses. The 19-tooth configuration places this pinion in the mid-range gearing spectrum, making it versatile for various motor sizes, track layouts and driving conditions. With a 3.17mm bore diameter, it accommodates the motor shafts found in most modern brushless and brushed motors commonly available in the UK RC market. The pinion's 4mm teeth width and 9mm overall length are precisely calculated for optimal engagement with spur gears without introducing unnecessary drag or resistance. The ultra-precise tooth shaping achieved through CNC cutting ensures each tooth maintains identical geometry, which is essential for vibration-free operation and long component lifespan. The special hardened steel material provides exceptional resistance to wear and stripping, allowing the pinion to maintain its precision and performance through countless hours of driving. The short profile design is particularly advantageous for modern, compact chassis layouts that demand space efficiency without compromising durability or power delivery. When paired with a compatible spur gear and quality bearings, this pinion delivers the kind of smooth, responsive performance that separates competitive setups from casual RC car UK builds.

Frequently Asked Questions

• Will this 19-tooth pinion fit my RC car? — The Corally C-71419 is compatible with any RC car, buggy or truck equipped with a 48 DP drivetrain system and a motor with a 3.17mm diameter shaft. Check your vehicle's specifications or consult the manufacturer's documentation to confirm your RC car uses 48 DP gearing. If you're unsure, our team at RC Model Shop can help you identify the correct specification for your particular model.
• What is the difference between this pinion and cheaper alternatives? — The Corally pinion is manufactured from special hardened steel using precision CNC machinery, ensuring perfect tooth geometry and concentricity. Cheaper alternatives often use lower-grade materials and less precise manufacturing, resulting in vibration, noise, premature wear and gear stripping. The investment in a quality Corally pinion pays dividends through improved performance, longevity and reliability during RC racing or recreational driving.
• How do I choose the right tooth count for my setup? — Pinion tooth count directly affects your gear ratio and vehicle performance. A 19-tooth pinion is a mid-range option; lower tooth counts (like 17T or 18T) provide more aggressive acceleration but lower top speed, whilst higher tooth counts (like 20T or 21T) offer higher top speed but less acceleration. Consider your motor's KV rating, your track layout and your driving preferences when selecting the appropriate pinion tooth count.
• Is this pinion suitable for beginners? — Yes, this is an excellent component for RC hobbyists of all experience levels. Whether you're new to RC cars or a seasoned racer, upgrading to a quality pinion like the Corally C-71419 will improve your vehicle's performance and reliability. The easy identification marking makes it simple to identify and install, and the durability means you'll get reliable service for months or years of driving.
• What motor shaft diameter does this pinion accommodate? — This pinion is specifically designed for motors with a 3.17mm diameter shaft, which is the standard used in many brushless and brushed motors for 1/10-scale RC cars, buggies and trucks. Before purchasing, verify that your motor has a 3.17mm shaft diameter to ensure proper fit and performance.
• How long will this pinion last? — With proper installation and maintenance, the hardened steel construction and precision engineering of this Corally pinion means you can expect thousands of miles of reliable service. The actual lifespan depends on driving conditions, motor power, spur gear quality and how frequently you use your RC car. Regular maintenance, including occasional cleaning and inspection, will maximise the life of this component.
• Why is concentricity important in a pinion gear? — Concentricity refers to how perfectly the gear teeth are centred on the bore. Precise concentricity ensures the pinion runs true when installed, eliminating vibration and ensuring even wear across all teeth. This translates to smoother operation, better handling response and improved longevity of the entire drivetrain system, from bearings to motor shaft.
• Can I use this pinion with different spur gears? — This 48 DP pinion is designed to mesh with any compatible 48 DP spur gear. You can experiment with different spur gear tooth counts to adjust your overall gear ratio without changing the pinion. This flexibility allows you to optimise your gearing for different track layouts and driving conditions without needing multiple pinions.
