Team Corally 32 DP Pinion Gear 23 Teeth Hardened Steel 5mm Shaft C-72523

Overview

The Corally 32 DP Pinion Short Hardened Steel 23 Teeth Shaft Dia. 5mm (C-72523) is a precision-engineered pinion gear designed for RC car enthusiasts across the UK who demand reliable, high-performance drivetrain components. Whether you're a competitive racer fine-tuning your RC buggy, a weekend basher pushing your RC monster truck to its limits, or an experienced modeller looking to upgrade your RC car's gearing system, this pinion gear represents the gold standard in precision and durability. Manufactured by Team Corally, a recognised leader in RC car components, this gear is crafted from special hardened steel and machined to exacting tolerances that ensure consistent performance lap after lap, race after race.

This 23-tooth pinion is part of Corally's comprehensive 32 DP (diametral pitch) gear range, allowing you to select the perfect gear ratio for your specific track conditions, driving style and performance goals. Whether you need faster acceleration, higher top speed, or better torque delivery, having access to multiple pinion tooth options means you can dial in your RC car's performance with surgical precision. The 5.0mm shaft diameter ensures compatibility with standard motor shafts found on most modern 1/10 scale RC cars and buggies, making this an essential upgrade or replacement component for your toolbox.

Built in Europe using advanced CNC machinery and quality control processes, this pinion gear delivers the concentricity, tooth accuracy and vibration-free operation that separates amateur-hour components from genuine competition-grade parts. Every gear is marked with its tooth count for quick and easy identification, so you'll never mix up your gearing options when preparing for a race or practice session.

Key Features

• Special Hardened Steel Construction — The pinion is manufactured from specially hardened steel that resists wear, chipping and stripping under extreme load and high-RPM operation, ensuring your gear ratio selection stays consistent throughout an entire racing season or extended bashing sessions on your RC car.
• CNC Cut Teeth for Perfect Geometry — Each tooth is machined using CNC (computer numerical control) equipment to achieve perfect tooth shape and concentricity, eliminating run-out and ensuring mesh with your spur gear is clean, efficient and silent, which means less power loss and smoother acceleration in your RC buggy or truck.
• Ultra-Precise Manufacturing Tolerances — Corally's production standards guarantee unparalleled concentricity (the gear runs perfectly true on its axis), which translates to vibration-free operation that keeps your RC car handling predictably even under hard cornering or high-speed straightaway driving.
• Module 32 DP Specification — The 32 DP (diametral pitch) specification is the industry standard for modern 1/10 scale RC cars, and this gear is compatible with all vehicles running 32 DP spur gears, making it a universal upgrade for the UK RC car community.
• 5.0mm Motor Shaft Compatibility — The 5mm bore diameter accepts standard 5mm motor shafts, ensuring it will fit virtually any brushless or brushed motor in your RC car without requiring adapters or modifications.
• Short Profile Design — The compact 13mm gear length and 6.20mm teeth width minimise rotating mass whilst maintaining structural integrity, reducing inertia and allowing your RC car to accelerate more responsively and handle weight distribution changes more effectively.
• Easy Identification — Every pinion is clearly marked with its tooth number, eliminating confusion when you're preparing multiple gearing options or swapping setups between different RC vehicles in your fleet.
• Made in Europe — Manufactured in Europe to strict quality standards, this component represents the reliability and precision that UK RC enthusiasts expect from their drivetrain components.
• Ideal for Gearing Optimisation — As a 23-tooth pinion, this gear sits in the mid-range of tooth counts, offering a balanced approach to acceleration and top speed; pair it with the appropriate spur gear to dial in the perfect gear ratio for your track or terrain.

Technical Performance

The Corally C-72523 pinion gear represents the pinnacle of modern drivetrain engineering for 1/10 scale RC cars in the UK market. Manufactured from special hardened steel using precision CNC machinery, this component is built to withstand the extreme forces generated by high-performance brushless motors and LiPo battery systems. The 32 DP specification is the universal standard for competitive and recreational RC car racing, and this 23-tooth pinion integrates seamlessly into any drivetrain running compatible spur gears. With a shaft diameter of exactly 5.0mm, it accommodates standard motor shafts found on virtually all modern 1/10 scale brushless and brushed motors, eliminating the need for expensive adapters or custom modifications. The teeth are cut using CNC precision grinding, ensuring that the tooth profile (the curved surface that meshes with your spur gear) is absolutely consistent across all 23 teeth, which minimises gear noise, reduces power loss through friction, and extends component lifespan significantly compared to lower-quality alternatives. The compact dimensions — just 13mm overall length with a 6.20mm teeth width — keep rotating mass to a minimum, which is critical for responsive acceleration and predictable handling in your RC buggy or short-course truck. The hardened steel material resists the micro-fractures and stress points that plague softer aluminum pinions, meaning you can run higher gear ratios and push your motor harder without risk of teeth stripping or catastrophic gear failure mid-race. Whether you're competing in national-level RC championships, racing at your local club track, or simply enjoying weekend bashing with friends, the precision engineering and robust construction of this Corally pinion ensures reliable, consistent performance session after session.

Frequently Asked Questions

• Is the Corally 32 DP pinion compatible with my RC car? — The C-72523 will fit any 1/10 scale RC car that uses a 5mm motor shaft and runs 32 DP gears, which covers the vast majority of modern brushless RC buggies, monster trucks, stadium trucks and short-course vehicles available in the UK market today.
• What is the difference between 32 DP and other gear specifications? — Diametral Pitch (DP) determines the size of teeth on the gear; 32 DP gears have finer, smaller teeth than 48 DP gears, for example, and are the industry standard for 1/10 scale racing. Lower DP numbers (like 16 DP or 24 DP) feature larger teeth and are found on larger-scale vehicles like 1/8 buggies.
• How do I choose the right pinion tooth count for my RC car? — The pinion tooth count directly affects your gear ratio; fewer teeth (like 19T or 21T) provide faster acceleration and lower top speed, whilst more teeth (like 25T or 27T) deliver higher top speed but require more motor power to accelerate. This 23-tooth option offers a balanced middle ground suitable for most track layouts and driving styles in the UK.
• Is hardened steel pinion better than aluminum? — Yes, significantly. Hardened steel resists wear, stripping and micro-fractures that occur under high-load racing conditions, making steel pinions essential for competitive use and sustained high-performance driving; aluminum pinions are lighter but wear faster and can strip teeth under extreme motor power.
• Will this pinion gear work with my specific RC brand? — The Corally pinion is brand-agnostic; if your car uses a 5mm motor shaft and 32 DP gearing, it will work regardless of whether you're running Traxxas, ARRMA, Losi, FTX, Kyosho or any other major RC brand available in the UK.
• How often should I replace my pinion gear? — With proper installation and maintenance, a hardened steel pinion like this Corally can last an entire racing season or longer; replacement is only necessary if you notice stripped teeth, wobbling, noise, or performance degradation during operation.
• What tools do I need to install this pinion? — You'll need a 2.0mm hex key (Allen key) to secure the pinion via the grub screw that locks it onto your motor shaft; most RC car kits include this size Allen key in their tool sets.
• Can I use this pinion with different spur gear tooth counts? — Yes, the beauty of having multiple pinion options like this 23T is that you can pair it with different spur gears to achieve various overall gear ratios; work with your local RC club or shop to calculate the exact ratio that suits your track conditions.
