Key Features

• Special Hardened Steel Construction — The pinion gear is manufactured from hardened steel specifically chosen for its exceptional toughness and durability, allowing it to withstand the intense forces generated during high-speed acceleration and aggressive cornering without stripping teeth or showing signs of wear, even after hundreds of hours of use.
• CNC-Cut Teeth for Perfect Geometry — Every tooth is cut using precision CNC machinery rather than stamped or moulded, ensuring absolute consistency in tooth shape, size, and spacing, which guarantees smooth, quiet engagement with your spur gear and eliminates the chatter and noise associated with inferior pinion gears.
• Ultra-True Running and Concentricity — The manufacturing process ensures unparalleled concentricity with tolerances so tight that the pinion runs true and balanced, eliminating vibration that would otherwise cause bearing wear, reduce efficiency, and create unwanted noise during operation.
• 64DP Module Rating — The 64DP (64 Diametral Pitch) specification means this pinion is compatible with all vehicles and gearboxes designed to accept 64DP gearing systems, giving you maximum flexibility when building or upgrading your RC car collection.
• 48-Tooth Specification — The 48-tooth count is a popular all-round specification that balances acceleration and top speed across a variety of track layouts and driving conditions, making it an excellent choice for both racing and recreational bashfield use.
• 3.17mm Motor Shaft Compatibility — The precision 3.17mm bore ensures a perfect fit on standard RC brushless and brushed motors, guaranteeing secure mounting without wobble or slippage during operation.
• Easy Identification Marking — Each pinion is clearly marked with the tooth number, allowing you to instantly identify the gear ratio and make quick gear changes when setting up for different tracks or conditions without confusion.
• 4.00mm Teeth Width — The 4mm face width provides excellent load distribution and contact area with your spur gear, maximising power transmission efficiency whilst minimising stress concentration on individual teeth.
• Compact 9mm Overall Length — The short profile ensures compatibility with tight gearbox designs without adding unnecessary weight or bulk to your RC vehicle's drivetrain.
• 1.5mm Hex Key Installation — The pinion is secured using a standard 1.5mm hex key, making installation and removal quick and straightforward using tools you'll already have in your RC toolkit.

Technical Performance

This Corally 64 DP pinion represents the gold standard in RC car drivetrain components, delivering the precision engineering and durability that serious RC enthusiasts demand. The hardened steel material has been carefully selected to resist the extreme forces generated during acceleration, cornering, and high-speed running, ensuring the pinion maintains its tooth profile and engaging surfaces even after thousands of meshing cycles with your spur gear. The CNC cutting process guarantees that every tooth is geometrically perfect, with consistent angles, depths, and spacing that eliminate the micro-slippage and noise that occurs with inferior gears. The ultra-precise concentricity means the pinion runs perfectly balanced with minimal runout, which is essential for smooth, vibration-free operation that translates into better drivetrain efficiency, longer bearing life, and ultimately faster lap times. The 48-tooth configuration offers an excellent compromise between acceleration and top speed across most track types — it's neither too aggressive nor too conservative, making it ideal for drivers who want to explore different racing environments or use the same vehicle for both timed laps and casual bashfield driving. The 3.17mm motor shaft diameter accommodates the vast majority of modern brushless and brushed motors used in competitive and recreational RC cars across the UK market. Whether you're upgrading your existing RC car, replacing a worn pinion on your race machine, or building a new vehicle from scratch, this Corally C-71348 pinion will provide dependable, high-performance service that keeps your RC car running at its best.

Frequently Asked Questions

• What is a pinion gear and why is it important for my RC car? — The pinion gear is a small driving gear that meshes with the larger spur gear in your RC car's gearbox. Together, they form a gear reduction system that increases the torque delivered to your wheels whilst reducing the motor speed. The pinion-to-spur gear ratio directly determines your vehicle's acceleration and top speed — a smaller pinion (fewer teeth) increases top speed but reduces acceleration, whilst a larger pinion (more teeth) boosts acceleration but lowers top speed. Choosing the correct pinion for your track layout is crucial for optimal performance.
• How do I know if a 48-tooth pinion is right for my RC car? — The 48-tooth pinion is one of the most popular all-around specifications, offering a balanced compromise between acceleration and top speed for most track layouts and driving styles. If you're not sure, 48 teeth is an excellent starting point. You can then experiment with adjacent sizes (47T or 49T) to fine-tune performance for your specific track conditions. Many serious RC racers carry multiple pinion options to optimise performance at different venues.
• What's the difference between this Corally pinion and cheaper alternatives? — This Corally C-71348 pinion is manufactured from special hardened steel using precision CNC cutting machinery, ensuring perfect tooth geometry, ultra-tight concentricity, and vibration-free operation. Cheaper pinions are often stamped or injection-moulded with inconsistent tooth spacing and poor runout characteristics, resulting in noisy, inefficient operation and premature tooth stripping. The Corally investment pays dividends through improved performance, longer component life, and better overall drivability.
• Is this pinion compatible with my RC car? — This pinion is compatible with any RC vehicle that uses 64DP gearing and has a motor with a 3.17mm shaft diameter. This includes a huge range of modern brushless and brushed RC cars, buggies, trucks, and other vehicles. Check your vehicle's specifications or user manual to confirm it uses 64DP gears — if it does, this pinion will work perfectly.
• How often should I replace my pinion gear? — With proper care and maintenance, a quality hardened steel pinion like this Corally unit should last for many hundreds of hours of running. However, if you notice any tooth stripping, damage, or the gear becomes noisy during operation, it's time to replace it immediately. Regular inspection and maintenance of your gearbox will extend the life of all drivetrain components.
• Can I use this pinion on different motor shafts? — No, this pinion is designed exclusively for 3.17mm motor shafts. Using it on a shaft of different diameter will result in either a loose fit (causing slippage) or damage to the bore. Always match the pinion bore diameter exactly to your motor shaft diameter.
