Associated Factory Team Aluminium Pinion Gear 28T 48DP 1/8 Shaft AS1346

Overview

The Associated Factory Team Aluminium Pinion Gear 28T 48DP is an essential upgrade component for serious RC enthusiasts running 1/8" motor shafts. Whether you're building a competitive RC buggy, truggy, or touring car, this lightweight pinion gear delivers the precision engineering and durability that Factory Team upgrades are recognised for. Designed specifically for 3.2mm (1/8") motor shafts, this 28-tooth pinion offers the perfect balance of performance and reliability for drivers who demand more from their RC car UK setup.

If you're serious about RC racing or weekend bashing with your RC model, upgrading from standard pinion gears to these hard-anodised Factory Team components will immediately improve your car's drivetrain performance. The 28-tooth configuration provides an excellent gear ratio option within the 48DP pitch standard, making it suitable for a wide range of Associated vehicles including the TC7.1, TC7.2, B6.1, B6.2, B6.3, B6.4, B74.2, T6.1, T6.2, T6.4, and many other Associated platforms. RC car UK builders and competitors consistently choose Factory Team pinions because they combine lightweight construction with long-term durability.

Replace your worn or standard pinion gears with this premium-grade upgrade and experience smoother gear mesh, improved acceleration response, and increased component longevity. The precision-machined 7075-T6 aluminium construction ensures this pinion will handle the demands of competitive RC racing, whether you're racing on a local track or practising in your spare time.

Key Features

• 7075-T6 Aluminium Construction — Machined from aerospace-grade 7075-T6 aluminium, this pinion gear offers exceptional strength-to-weight ratio, meaning you get a robust component that won't add unnecessary mass to your RC car's drivetrain, directly improving acceleration and handling characteristics.
• Hard-Anodised Finish for Long Life — The hard-anodised surface treatment provides a protective barrier that resists wear, corrosion and damage from repeated gear mesh cycles, ensuring your pinion maintains precise tooth geometry and smooth operation throughout its service life, reducing the need for frequent replacements.
• Precise 28-Tooth 48DP Profile — The exact 28-tooth count with 48 diametral pitch (48DP) specification ensures perfect compatibility with Associated Factory Team spur gears, delivering smooth, consistent gear mesh that maximises power transfer and minimises drivetrain noise and vibration.
• Two Set-Screw Holes — Dual set-screw mounting points provide secure, reliable fastening to your 3.2mm (1/8") motor shaft, preventing slippage during acceleration and braking while allowing easy installation and removal when you need to swap ratios or maintain your RC model.
• Laser-Etched Tooth Count — Each pinion features laser-etched tooth identification, making it instantly recognisable at a glance, essential when you're running multiple pinion ratios for different track conditions or racing scenarios, and helping prevent accidental installation of incorrect gears.
• Factory Team Hopup Quality — As an official Factory Team component, this pinion represents the same quality, precision engineering and material science used in Associated's factory race teams, meaning you're upgrading to competition-grade equipment without the competition-grade price tag.
• Lightweight Design — Compared to heavier brass or steel alternatives, the aluminium construction significantly reduces rotating mass in your drivetrain, meaning your motor works more efficiently, your battery delivers better performance, and your RC car accelerates more responsively.

Technical Performance

This pinion gear represents cutting-edge drivetrain technology for 1/8" shaft RC cars. The 28-tooth 48DP specification places it in the mid-range of tooth counts, making it an excellent choice for balanced performance across various track conditions and driving styles. The hard-anodised 7075-T6 aluminium delivers superior wear resistance compared to standard steel or nickel-plated alternatives, maintaining precise tooth geometry even after thousands of gear mesh cycles typical of competitive RC racing. The dual set-screw design ensures rock-solid retention on your motor shaft, eliminating the drivetrain slippage that can cost you races or damage your RC model. The laser-etched tooth count is a practical feature that prevents ratio confusion and speeds up maintenance routines. Compatible with a comprehensive range of Associated platforms including the TC7, TC7.2, B6 series, B74 series, T6 series, SC series, and many others, this pinion is a must-have spare or upgrade for any RC car UK driver running an Associated vehicle. The lightweight aluminium construction directly benefits performance by reducing inertia in the drivetrain, allowing your brushless motor to deliver more responsive acceleration and your ESC to achieve smoother speed control.

Frequently Asked Questions

• Is the Associated 28T 48DP pinion suitable for beginners? — Yes, absolutely. While this is a premium Factory Team upgrade component, it's no more complex to install than standard pinions. If you're learning to work on your RC car and want to experience genuine performance improvements, upgrading to quality Factory Team pinions is an excellent first mod. The dual set-screw design actually makes installation more secure and foolproof than some alternatives.
• What Associated RC cars will this 28T pinion fit? — This pinion is designed for any Associated vehicle with a 3.2mm (1/8") motor shaft and 48DP spur gear compatibility. Confirmed compatible platforms include TC7.1, TC7.2, B6.1, B6.1D, B6.2, B6.3, B6.4, B6.4D, B74.1, B74.2, B74.2D, T6.1, T6.2, T6.4, SC6.1, SC6.2, SC6.4, DR10, DR10M, RB10, RB10 Retro, SR10, RC10SC6.1, RC10SC6.2, RC10CC, RC10DR, and many other Associated models from the contemporary range. Check your vehicle manual to confirm shaft size and pitch standard.
• What is the difference between the 28T and other tooth counts like 26T or 30T? — Tooth count directly affects your gear ratio and performance characteristics. The 28-tooth pinion represents a mid-range option: smaller pinions like 26T will increase your top speed but reduce acceleration and torque, whilst larger pinions like 30T will give you stronger acceleration and lower top speed. Choose 28T for a balanced setup, drop to 26-27T for high-speed tracks, or step up to 29-32T for tight technical courses requiring maximum acceleration.
• Why should I upgrade from standard to Factory Team aluminium pinions? — Factory Team pinions deliver three major benefits: first, the 7075-T6 aluminium reduces rotating mass, improving acceleration and motor efficiency; second, the hard-anodised finish lasts far longer than standard plating, reducing replacement frequency; and third, the precision manufacturing and laser etching ensure perfect fitment and easy identification. For the modest investment, you'll notice smoother power delivery and extended component life.
• How long will this pinion last? — Hard-anodised 7075-T6 aluminium is significantly more durable than standard steel or brass alternatives. With proper maintenance and installation, you can expect thousands of racing cycles before wear becomes noticeable. The hard-anodised surface protects against corrosion, galling, and abrasive wear, meaning your pinion will maintain its precise tooth geometry far longer than budget alternatives.
• Is this pinion waterproof? — The pinion gear itself is metal and inherently water-resistant. However, make sure your motor shaft and bearing system are properly sealed, as moisture can affect the bearing and shaft rather than the gear itself. Standard RC car maintenance practices apply.
