Manufactured by Team Corally, a recognised leader in RC component engineering, this 30-tooth pinion is precision-engineered from special hardened steel and produced using advanced CNC cutting technology. The gear is designed to work seamlessly with all 48DP gearing systems, allowing you to dial in the perfect gear ratio to match your motor, ESC, track conditions and driving style. Available in all gearing sizes across the 48DP range, the C-71430 gives you the flexibility to experiment with different ratios until you find the sweet spot for maximum speed, acceleration and efficiency.

This is a component that transforms your RC car's performance characteristics, whether you're looking for faster acceleration from a standing start, higher top speed on open track, or better overall efficiency and lower heat generation. Every RC car enthusiast knows that gear ratio selection is absolutely critical to unlocking your vehicle's true potential, and this Corally pinion offers the precision tolerances and engineering excellence needed to make measurable improvements.

Key Features

• Special Hardened Steel Construction — Manufactured from premium-grade hardened steel, this pinion is designed to withstand the extreme forces generated during acceleration, cornering and sustained high-speed running, ensuring longevity and reliability even under aggressive driving conditions.
• CNC Cut Teeth for Perfect Tooth Shape and Concentricity — Each tooth is precision-cut using advanced CNC machinery to deliver absolutely perfect tooth geometry and concentricity, which means vibration-free operation, smoother power delivery, and significantly reduced wear on your spur gear.
• Module 48DP Specification — This 30-tooth pinion is engineered to the 48DP (Diametral Pitch) standard, making it compatible with all 48DP spur gears and drivetrain components, giving you maximum flexibility when building or upgrading your RC car.
• Ultra-Precise Tooth Shaping — Team Corally has invested in special gear manufacturing technology to ensure every pinion features ultra-precise tooth shaping, which directly translates to improved efficiency, quieter operation, and better power transmission from your motor to your wheels.
• Ultra-True Running Geometry — The engineering precision extends to the overall geometry and concentricity of the gear, ensuring ultra-true running that eliminates vibration, reduces friction losses, and extends the lifespan of both this pinion and your spur gear.
• 3.17mm Motor Shaft Diameter — Engineered for compatibility with standard 3.17mm motor shafts found on most brushless motors used in competitive RC cars, ensuring perfect fit and secure engagement with your existing drivetrain.
• Easy Identification Marking — Each pinion is clearly marked with the tooth count for quick and easy identification during setup changes, allowing you to swap ratios rapidly without confusion or mistakes.
• Made in Europe — Manufactured to the highest European engineering standards, guaranteeing consistent quality, tight tolerances, and the reliability that RC competitors and hobbyists demand.
• Available in All Gearing Sizes — This model is part of a comprehensive range of 48DP pinion sizes, allowing you to find the perfect gear ratio for any track condition, from tight technical circuits to wide-open speed runs.

Technical Performance

This Corally 48DP pinion represents the pinnacle of RC gear engineering, combining advanced materials science with precision manufacturing to deliver performance that serious competitors and dedicated hobbyists will immediately recognise. The 30-tooth configuration works in conjunction with your spur gear to create your overall gear ratio—a critical factor that determines your RC car's acceleration characteristics, top speed potential, and overall efficiency. The special hardened steel material has been specifically selected to resist the intense stresses generated by high-powered brushless motors driving through tight gear meshes at thousands of RPM. The CNC-cut tooth profile ensures that power is transmitted smoothly from your motor's output shaft through to your drivetrain, minimising energy losses and reducing the heat generation that can degrade performance during extended racing sessions.

The 4mm tooth width and 9mm overall gear length have been engineered to provide optimal contact with your spur gear whilst maintaining a compact footprint within your RC car's transmission housing. The 1.5mm hex key requirement for installation makes setup straightforward for anyone with basic RC maintenance tools. Every aspect of this pinion's design has been optimised for vibration-free operation, which is critical because any vibration or runout will cause noise, reduce efficiency, and accelerate wear on both components. The ultra-true running geometry achieved through precision CNC manufacturing ensures that your transmission runs as smoothly as possible, translating directly into better handling, more predictable power delivery, and improved overall performance on track. For anyone running a competitive RC car or seeking to maximise their setup's potential, upgrading to a precision-engineered pinion like this C-71430 represents a measurable and noticeable improvement over standard components.

Frequently Asked Questions

• What is a pinion gear and why do I need to change it? — A pinion gear is the small gear attached to your motor's output shaft that meshes with the larger spur gear to create your overall gear ratio. By changing the number of teeth on your pinion, you adjust your car's acceleration and top speed characteristics. More teeth equals lower gear ratio (faster acceleration, lower top speed); fewer teeth equals higher gear ratio (slower acceleration, higher top speed). This C-71430 30-tooth pinion is ideal for technical tracks where mid-range acceleration is valued, or as part of a lower gear ratio for speed-focused circuits when paired with a larger spur gear.
• Will this pinion work with my RC car? — This pinion is compatible with any RC car that uses 48DP gears and has a 3.17mm motor shaft. This includes many popular electric RC cars from various manufacturers. However, you must ensure your existing spur gear is also 48DP; mixing different gear pitches (32DP, 48DP, 64DP) will result in poor mesh and potential damage. If you're unsure about compatibility, we recommend checking your vehicle's manual or contacting our team at RC Model Shop for guidance.
• What is the difference between this hardened steel pinion and softer alternatives? — Hardened steel provides superior durability and resistance to wear compared to softer materials. It can handle higher power levels from brushless motors and maintains its tooth shape longer, resulting in more consistent performance and a longer lifespan. This is especially important if you're running a high-KV motor or pushing your RC car hard in competitive or intensive recreational use.
• How does changing the pinion affect my RC car's performance? — The pinion tooth count directly affects your gear ratio. This 30-tooth pinion will perform differently depending on what spur gear you pair it with. Lower pinion tooth counts increase top speed but reduce acceleration; higher tooth counts like this 30T improve mid-range acceleration and torque. Your final gear ratio is calculated by dividing spur gear teeth by pinion teeth—for example, a 78-tooth spur with this 30-tooth pinion gives you a 2.6:1 ratio. Experiment with different combinations to find what works best for your track and driving style.
• Is precision pinion gear quality really noticeable? — Absolutely. Precision-engineered gears like this Corally C-71430 eliminate vibration, noise and inefficiency that cheaper components can introduce. You'll notice smoother power delivery, quieter operation, and more consistent handling. In competitive racing, these small improvements can add up to better lap times. Even for recreational drivers, the improved smoothness and reliability make the investment worthwhile.
• How do I install this pinion gear? — Installation typically involves removing your motor from the transmission case, unbolting the old pinion using a 1.5mm hex key, sliding this new 30-tooth pinion onto your motor shaft, and securing it in place. Consult your vehicle's manual for specific instructions, as the process varies by model. Ensure the pinion meshes correctly with your spur gear—you should be able to slide a thin piece of paper between them with slight resistance. If you're not confident, our RC Model Shop team can provide installation support.
