Key Features
- Special Hardened Steel Construction — The pinion is manufactured from special hardened steel that provides superior toughness and durability compared to standard steel alternatives, meaning it will withstand repeated engagement cycles and maintain its integrity through extended racing sessions without premature wear or tooth stripping.
- CNC-Cut Teeth with Perfect Concentricity — Each tooth has been precision-cut on a special gear machine with ultra-tight tolerances, guaranteeing perfect tooth geometry and concentricity that eliminates runout and ensures smooth, quiet engagement with your spur gear for vibration-free operation.
- Ultra-Precise Tooth Shaping — The advanced tooth profile created during CNC manufacturing provides optimal contact patterns with your main spur gear, reducing friction losses and maximising power transfer efficiency to the wheels of your RC car.
- Ultra-True Running Performance — Thanks to the precision manufacturing process and hardened steel material, this pinion runs with exceptional accuracy, delivering consistent performance lap after lap without the vibration issues that can develop with lower-quality gears.
- 28-Tooth Configuration — The 28-tooth count provides a balanced gear ratio option that works perfectly with 48 DP systems, allowing you to fine-tune your RC car's acceleration and top speed characteristics for your preferred driving style and track conditions.
- 3.17mm Motor Shaft Compatibility — Designed specifically for 3.17mm diameter motor shafts, this pinion fits all RC cars and electric motors utilising this standard shaft size, making it a universal spare for most modern brushless RC vehicles in the UK market.
- Easy Identification Marking — Each pinion is clearly marked with the tooth number, allowing you to instantly identify the gear size in your spares collection and select the correct ratio for your current setup without confusion.
- Complete 48 DP Gearing System Availability — Corally manufactures this pinion as part of a complete range of 48 DP gearing options, meaning you can source matching spur gears and other components from the same product family for consistent performance throughout your drivetrain.
Technical Performance
The Corally 48 DP Pinion represents a leap forward in pinion gear engineering for RC cars. Manufactured using special hardened steel and precision CNC machining, this component delivers the kind of build quality you'd expect from a top-tier RC component manufacturer. The 48 DP (Diametral Pitch) specification refers to the tooth size standard, with 48 DP being one of the most common pitches used in modern RC car drivetrains. At 28 teeth, this pinion provides a mid-range gearing option that strikes an excellent balance between acceleration response and top-end speed. The 3.17mm motor shaft diameter is the industry standard for most brushless RC car motors, ensuring universal compatibility across the vast majority of modern electric RC vehicles available to UK hobbyists. With a tooth width of 4.00mm and overall gear length of 9.00mm, the pinion is compact and fits into standard RC car gearboxes without modification. The precision tolerances maintained throughout manufacturing mean that run-out is minimised, resulting in smooth engagement with your main spur gear and reduced vibration during operation. The 1.5mm hex key size makes installation and removal straightforward, and the hardened steel material ensures that the teeth maintain their profile through thousands of engagement cycles, preventing the tooth wear and chipping that can occur with softer materials. Whether you're running a competitive racing setup or enjoying casual weekend RC car bashings, this pinion will deliver consistent, reliable performance.

Frequently Asked Questions
- Will this 48 DP pinion fit my RC car? — The Corally C-71428 is compatible with any RC car that uses 48 DP gearing and has a 3.17mm motor shaft diameter. This specification covers the vast majority of modern brushless RC cars available in the UK, including vehicles from brands like Traxxas, ARRMA, Losi, and many others. Check your RC car's manual or existing pinion gear to confirm the pitch and shaft size before ordering.
- What is the advantage of hardened steel over standard steel? — Hardened steel provides significantly greater durability and wear resistance compared to standard steel pinions. The special hardening process increases the material's hardness, which means the teeth are less prone to stripping, chipping, or developing wear patterns during intense driving sessions. For serious RC car enthusiasts, hardened steel represents a worthwhile investment in component longevity.
- How many teeth should I choose for my RC car? — The 28-tooth configuration in this pinion provides a mid-range gearing option. Fewer teeth (like 26T) will give you faster acceleration and slightly higher top speed, whilst more teeth (like 30T) will provide more torque and lower top speed. The 28-tooth ratio is ideal if you want a balanced, versatile setup suitable for mixed track conditions.
- Is this pinion suitable for beginners? — Absolutely. Whilst this is a high-quality component, pinion gears are a consumable spare part in any RC car setup. Beginners should keep spare pinions on hand, as they can wear or be damaged during crashes. The Corally 48 DP is an excellent beginner-friendly spare option because it's affordable, widely compatible, and the hardened steel construction means it will last longer than budget alternatives.
- What makes Corally gears better than other brands? — Corally pinions are manufactured in Europe using precision CNC machinery and special hardened steel, which ensures tighter tolerances and superior concentricity compared to many competitors. The ultra-true running characteristics mean less vibration and smoother power delivery, which translates to better handling and longer component lifespan. For UK RC enthusiasts who want reliable, performance-focused spare parts, Corally is a recognised manufacturer of choice.
- Do I need to replace my pinion regularly? — With normal use and proper maintenance, a hardened steel pinion like this Corally unit will last many hours of driving. However, pinions do eventually wear, particularly if you're running tight gearing or driving on abrasive surfaces. Keeping spare pinions in different tooth counts allows you to dial in your RC car's performance as needed and always have a backup ready for track days.
