Key Features

• Special Hardened Steel Construction — Manufactured from high-quality hardened steel, this pinion gear offers exceptional toughness and durability, resisting wear and deformation even under demanding racing conditions or high-speed bashing, which means your investment will last through countless hours of driving enjoyment.
• CNC-Cut Teeth with Perfect Concentricity — Each tooth is precisely cut on a specialised gear machine using CNC technology, ensuring ultra-precise tooth shaping and perfect concentricity that eliminates runout and vibration for smooth, quiet operation and improved performance across all driving conditions.
• Ultra-True Running for Vibration-Free Operation — The precision engineering delivers ultra-true running characteristics, meaning your drivetrain operates with minimal vibration, which reduces stress on connected components, improves handling feel and extends the lifespan of your entire drivetrain system.
• 64 DP Gear Pitch — Compatible with the industry-standard 64 DP (Diametral Pitch) specification, this pinion works seamlessly with spur gears of the same pitch specification, allowing you to adjust your gear ratio for different track conditions and driving styles without compatibility issues.
• 33-Tooth Configuration — The 33-tooth count provides a balanced gear ratio suitable for a wide range of RC car applications, offering a compromise between acceleration and top speed that works well for both racing and recreational driving across different track layouts.
• 3.17mm Motor Shaft Compatibility — Designed specifically for motors with 3.17mm shaft diameter (a common standard across many brushless and brushed RC motors), ensuring a secure fit and reliable power transmission without slipping or play.
• Compact Short Profile — The short design minimises the gear's overall length (just 9mm) whilst maintaining full tooth width (4mm), allowing it to fit in tight motor compartments and reducing complexity in your drivetrain layout without compromising strength.
• Easy Identification Marking — Each pinion is clearly marked with its tooth number, eliminating confusion during setup, maintenance or when swapping gears for different track conditions, making it simple to keep your spare parts organised.
• European Manufacturing Quality — Proudly made in Europe using rigorous quality control standards, this component reflects Team Corally's commitment to delivering professional-grade RC components that meet the exacting demands of competitive and recreational drivers alike.
• Precise 1.5mm Hex Key Fitting — The pinion is secured using a standard 1.5mm hex key (Allen key), a size found in virtually every RC enthusiast's toolkit, making installation, removal and maintenance straightforward without requiring specialist tools.

Technical Performance

The Corally 64 DP Pinion Short represents the pinnacle of precision gear manufacturing for RC cars in the UK market. Every aspect of this component has been engineered to deliver consistent, reliable performance under the demanding conditions of competitive racing or aggressive bashing. The special hardened steel material has been selected specifically for its ability to withstand the enormous torque and impact forces generated by modern brushless motors whilst resisting the gradual wear that can develop during extended use. The CNC cutting process creates teeth with such precision that the gear achieves unparalleled concentricity—meaning the teeth are perfectly centred on the gear's axis, with no runout or wobble. This level of precision is crucial because even tiny amounts of runout can cause vibration, noise, and premature wear in your drivetrain. The 64 DP pitch specification means this pinion is designed to work with spur gears of matching pitch, creating a complete drivetrain system that operates smoothly and efficiently. At 33 teeth, this pinion offers versatility across numerous vehicle types and driving styles; the gear ratio it produces varies depending on which spur gear you pair it with, allowing you to fine-tune your vehicle's performance characteristics for specific track conditions, weather, or personal preference. The 4mm tooth width ensures sufficient contact surface for reliable power transmission without introducing excessive friction or heat, whilst the compact 9mm overall length and 3.17mm shaft bore make it compatible with a vast range of RC cars currently popular in the UK, from touring cars to buggies and trucks. Whether you're running a 2S, 3S, or 4S LiPo battery system powering your RC car's motor, this pinion can handle the power transmission reliably. The 1.5mm hex key fitting is a standard specification that makes installation quick and secure, with no special tools required.

Frequently Asked Questions

• What is the difference between 64 DP and other gear pitch specifications like 48 DP or Mod 1? — The DP (Diametral Pitch) specification determines the size and spacing of gear teeth; 64 DP gears have smaller, more closely-spaced teeth compared to lower DP numbers like 48 DP, resulting in smoother operation, more precise control, and typically better performance in high-speed applications. You must match the DP specification of your pinion with your spur gear—a 64 DP pinion will not mesh correctly with anything other than a 64 DP spur gear.
• Will this pinion work with my RC car? — The Corally C-71333 pinion is compatible with any RC car that uses 64 DP gears and has a motor with a 3.17mm shaft diameter. This includes many popular touring cars, buggies, and trucks from brands such as Team Corally, Team Associated, TLR, and others. Check your vehicle's specifications or owner's manual to confirm these requirements before purchasing.
• How do I know which spur gear to pair with this 33-tooth pinion? — The gear ratio is calculated by dividing the spur gear tooth count by the pinion tooth count (e.g., 75-tooth spur divided by 33-tooth pinion = 2.27:1 ratio). For higher acceleration and low-speed torque, choose a smaller spur gear; for higher top speed, choose a larger spur gear. Your vehicle's manual or Team Corally's website typically recommends specific pairings for different track conditions.
• Why is hardened steel better than plastic or aluminium gears? — Hardened steel offers superior durability, wear resistance, and strength compared to plastic or softer metals, meaning your pinion will maintain its tooth geometry longer and be less likely to strip, crack, or deform under high-torque conditions or impact loads. This longevity makes hardened steel gears a cost-effective choice despite higher initial expense.
• How often should I replace this pinion? — With proper maintenance and reasonable use, a quality hardened steel pinion like the Corally C-71333 can last hundreds of running hours. Replace it if you notice visible tooth damage, grinding noises, or loss of smoothness in gear operation. High-speed or competitive racing may require more frequent replacement than casual bashing.
• Is this suitable for beginners? — Yes, absolutely. Whilst pinion gears are technically a component you'll work with during vehicle setup and maintenance, the Corally C-71333 is an excellent entry-level option. It's standard-sized, fits a wide variety of vehicles, and the straightforward 1.5mm hex key installation is well within a beginner's capability following your vehicle's assembly instructions.
• What makes CNC-cut teeth better than stamped or moulded teeth? — CNC cutting provides superior precision and consistency compared to stamped or moulded processes; each tooth is mathematically perfect in shape and spacing, resulting in quieter, smoother operation, better mesh with the spur gear, and extended component lifespan due to reduced stress concentrations and more even load distribution.
