• Hard-Anodised Finish — The hard-anodised coating provides a protective oxide layer that significantly extends the working life of the gear by resisting wear from constant mesh contact with your spur gear, whilst also offering superior corrosion resistance compared to raw aluminium surfaces.
• Dual Set-Screw Holes — Two independent set-screw attachment points ensure rock-solid security on your motor shaft, preventing slippage during aggressive acceleration or cornering that could cause timing loss and poor handling characteristics on track or trail.
• Laser-Etched Tooth Count — The tooth count is precisely etched directly onto the gear surface using laser technology, making it instantly recognisable during setup changes, gear ratio calculations, or when managing multiple pinion sizes in your spares collection without requiring inspection under magnification.
• Factory Team Quality — As an official Associated Factory Team component, this pinion gear undergoes rigorous quality control and precision machining to ensure concentricity, tooth profile accuracy and bore tolerances that meet racing standards, guaranteeing smooth engagement with your spur gear and minimal drivetrain noise.
• 27-Tooth Specification — The 27T size represents a mid-range ratio in the Associated pinion lineup, offering balanced performance characteristics suitable for varied track conditions, mixed terrain usage, and general all-round RC car operation without extreme specialisation toward speed or acceleration.
• 48 Diametral Pitch (DP) Rating — The 48DP specification indicates the gear is designed for precision mesh with 48-pitch spur gears, a standard sizing convention in RC applications that ensures proper engagement geometry and minimises backlash-related issues during operation.

Technical Performance

The Associated Factory Team Aluminium Pinion Gear 27T 48DP represents genuine engineering excellence in RC drivetrain components. Precision-machined from 7075-T6 aluminium alloy, this gear delivers measurable benefits over standard steel alternatives through its optimised weight distribution and superior material properties.

Frequently Asked Questions

• What RC cars are compatible with the Associated Factory Team 27T 48DP pinion gear? — This pinion gear fits any RC car with a 1/8 inch (3.2mm) motor shaft bore designed for 48-pitch spur gears. The Associated compatibility list includes models like the TC7.1, TC7.2, B6.1, B6.2, B6.3, B6.4, B74.2, T6.1, T6.4, RC10SC6.1, RC10SC6.2, RC10CC, RC10DR and numerous other Associated platforms. Cross-compatibility with other manufacturers' vehicles depends on matching your motor shaft diameter and spur gear pitch specifications. We recommend checking your vehicle manual or contacting our Walsall store on 01543 577278 if you're unsure about fitment for your specific RC car model.
• How does the 27T pinion gear compare with other tooth counts in the Associated range? — The 27T represents a mid-range pinion size within Associated's pinion lineup spanning from 17T through 34T. Lower tooth counts like 17T, 18T and 19T create lower gear ratios for maximum top speed on high-grip tracks, whilst higher counts like 30T, 31T, 32T, 33T and 34T deliver more aggressive acceleration gearing suited to loose terrain or technical courses. The 27T offers balanced characteristics between acceleration and top speed, making it an excellent general-purpose choice for mixed conditions. If you're running consistently on tight technical tracks, you might prefer a higher tooth count for quicker acceleration; conversely, if your local UK track features long straights with high grip, a lower tooth count would favour top speed.
• Why choose aluminium pinion gears over standard steel versions? — Aluminium pinion gears from Factory Team provide several meaningful advantages over conventional steel alternatives. The primary benefits include weight reduction, which decreases rotating mass in your drivetrain and can improve acceleration response and handling characteristics. The hard-anodised finish provides superior durability compared to bare steel, resisting corrosion and extending working life in damp UK conditions. Aluminium gears are also easier to identify during setup changes thanks to their distinct appearance and laser-etched tooth counts. The 7075-T6 aluminium alloy used in this gear is specifically chosen for its exceptional strength properties, delivering reliability comparable to steel whilst maintaining the weight advantages. For serious RC enthusiasts in the UK seeking genuine performance upgrades, Factory Team aluminium pinion gears represent excellent value.
• What is the difference between 48DP and other diametral pitch ratings? — Diametral Pitch (DP) describes the tooth spacing standard for your gears. 48DP is a fine-pitch specification commonly used in 1/10 and 1/8 scale RC applications, offering a good balance between strength and precision. 64DP gears feature finer teeth for tighter tolerances and smoother engagement, whilst 32DP represents a coarser pitch used in larger-scale vehicles. The 48DP specification on this gear means it must mesh with 48DP spur gears; mixing different pitch ratings will result in poor engagement, excessive backlash and potential damage. Always verify your spur gear pitch matches your pinion specification before purchasing.
• How do I install the set screws on this pinion gear? — The 27T pinion gear features two set-screw holes positioned on opposite sides of the bore for balanced clamping pressure. Insert the supplied set screws into these holes and tighten them evenly using an appropriate hex wrench or Allen key, ensuring the pinion is positioned correctly on your motor shaft before full tightening. Avoid over-tightening, which could damage the motor shaft or create binding. Many RC enthusiasts apply a small amount of threadlocker compound to the set screw threads to prevent loosening during aggressive driving. If you're unsure about proper installation procedure, our team at RC Model Shop in Walsall is happy to provide guidance.
• Is this suitable for beginner RC car enthusiasts? — Whilst this pinion gear is a quality component suitable for drivers of any experience level, it is a replacement spare part rather than a complete RC car. You'll need an existing RC vehicle with matching shaft bore and spur gear pitch to use this component. Beginners exploring ready-to-run RC cars for the first time might start with a complete beginner-friendly vehicle like an Associated entry-level platform, then progressively add Factory Team upgrade components like this pinion gear as they develop their skills and understanding of RC car setups.
• Can I use this pinion gear on other RC platforms besides Associated vehicles? — Potentially yes, provided your RC vehicle features a 1/8 inch (3.2mm) motor shaft bore and uses 48-pitch spur gears. Many manufacturers including Team Losi, HPI, Kyosho and others produce vehicles compatible with standard 48DP pinion sizing. However, you must verify shaft bore diameter and spur gear pitch specifications match before purchasing. If compatibility is unclear, contact our helpful team at RC Model Shop before ordering.
• How often should I replace my pinion gear? — Pinion gear lifespan depends heavily on usage frequency, driving style and maintenance practices. Hard-anodised aluminium gears like this Factory Team component typically outlast standard steel versions significantly. Regular inspection under magnification can reveal premature tooth wear patterns. Most RC enthusiasts find quality pinion gears provide extended reliable service spanning many months of regular driving before replacement becomes necessary. Signs of wear include visible tooth profile degradation, increased drivetrain noise, or visible damage to the hard-anodised coating. The laser-etched tooth count won't fade or wear off, maintaining identification throughout the gear's working life.
