AS81389

Overview

The Associated RC8B3.1e Spur Gear 46T MOD1 (Kit) AS81389 is an essential replacement component for owners of the Team Associated RC8B3.1e 1/10 scale electric off-road buggy. This genuine factory part is specifically engineered to restore your RC car's drivetrain to its original specification, ensuring your vehicle continues to perform at its best. Whether you're a dedicated competitor, an experienced weekend basher, or someone exploring the world of RC cars in the UK, maintaining your RC car's drivetrain components is crucial for consistent performance and longevity.

Spur gears are fundamental to the transmission system of any RC buggy, transferring power from the motor to the wheels through precise mechanical engagement. Over time, even the highest quality spur gears can become worn through regular use, affecting acceleration, top speed consistency and overall drivetrain efficiency. This genuine Team Associated replacement gear is designed specifically for the RC8B3.1e platform, providing the exact tooth profile and pitch required for perfect gear mesh with your pinion gear and transmission components. Choosing an authentic replacement part ensures compatibility, durability and the performance characteristics you expect from your RC buggy.

RC Model Shop stocks this component as part of our comprehensive range of Team Associated spares and upgrades for the RC8B3.1e and related models. We recognise that enthusiasts investing in quality RC cars deserve genuine replacement parts that maintain the engineering standards of the original vehicle. This kit specification spur gear is ideal for racers looking to refresh worn drivetrain components between competitions, or for bashers who demand reliable performance during intense off-road sessions.

Key Features

• 46-tooth MOD 1 spur gear — This precision-manufactured spur gear features 46 teeth with MOD 1 pitch specification, which is the standard configuration for the RC8B3.1e buggy and ensures perfect meshing with your transmission system, maintaining optimal power delivery and efficiency.
• Genuine Team Associated replacement part — Manufactured by Team Associated to exact factory specifications, this component guarantees the same quality, durability and performance characteristics as the original part that came with your RC car, with no compromises on material or engineering.
• Kit specification supply — Supplied in kit format, meaning it arrives ready to install directly into your RC8B3.1e without requiring additional components or modifications, making it straightforward to replace your worn gear and get back to driving.
• Stock gearing restoration — Perfect for drivers who want to return their RC8B3.1e to its original factory gearing configuration after experimenting with alternative gear ratios, or to simply maintain consistent performance characteristics across multiple vehicles.
• Ideal for all RC driving styles — Whether you're competing in organised RC racing events, enjoying casual off-road bashing with friends, or developing your skills as an RC enthusiast in the UK, this replacement gear helps maintain the performance standards your RC8B3.1e deserves.
• Worn drivetrain component replacement — Regular use of your RC buggy will naturally result in wear to the spur gear teeth, which can manifest as lost acceleration or inconsistent top speed; this new gear restores your drivetrain to like-new condition.

Technical Performance

The Associated RC8B3.1e Spur Gear 46T MOD1 is engineered to the precise specifications required for the RC8B3.1e transmission system. With 46 teeth and MOD 1 pitch, this spur gear provides the stock gearing ratio designed by Team Associated for balanced performance across a wide range of racing and recreational driving scenarios. The gear is manufactured from high-quality materials selected for their durability and resistance to the repeated engagement stresses that occur during normal RC buggy operation. The tooth profile is precisely machined to ensure smooth meshing with your pinion gear, minimising backlash and maintaining efficient power transfer from the brushless motor to your RC car's wheels. For competitive RC drivers in the UK, maintaining fresh spur gears is a critical aspect of vehicle maintenance; worn teeth reduce acceleration response, can cause drivetrain vibration, and may lead to premature damage to other transmission components. This genuine Team Associated part meets all factory specifications and has been proven through thousands of hours of testing across professional racing circuits and casual driving environments. The MOD 1 pitch specification is standard across the RC8B3.1e platform, making this gear an essential spare for drivers who maintain multiple vehicles or who require backup components for competition days. Installation is straightforward for anyone with basic RC car maintenance knowledge, using standard RC tools.

Frequently Asked Questions

• Is this spur gear compatible with my RC8B3.1e buggy? — Yes, this is a genuine Team Associated replacement part specifically designed for the RC8B3.1e 1/10 scale electric off-road buggy. It features 46 teeth with MOD 1 pitch, which is the stock gearing specification for this model. If you own an RC8B3.1e, this part will fit perfectly into your transmission system without any modifications.
• Why should I replace my spur gear if my RC buggy is still working? — Even though your RC car may still function with a worn spur gear, replacing it helps maintain optimal performance. Worn gear teeth reduce acceleration response, can cause grinding noises, and may eventually damage other drivetrain components like your pinion gear or transmission case. Regular spur gear replacement is part of standard RC vehicle maintenance and keeps your buggy performing at its best.
• What is the difference between MOD 1 and other spur gear specifications? — MOD (module) refers to the pitch specification of the gear teeth. MOD 1 is the standard specification for the RC8B3.1e; using a different MOD specification would result in improper meshing with your pinion gear, poor performance, and potential transmission damage. Always ensure you are using the correct MOD specification for your vehicle.
• How often should I replace my spur gear? — This depends on how frequently you use your RC8B3.1e and the intensity of your driving. Competitive racers might replace their spur gears several times per season, whilst casual drivers might only need to replace them annually or less frequently. Inspect your spur gear regularly for chipped or excessively worn teeth; if you notice damage, it's time to install this replacement part.
• Is this an official Team Associated part? — Yes, this is a genuine Team Associated replacement part manufactured to the exact specifications of the original spur gear that came with your RC8B3.1e. Choosing genuine parts ensures compatibility, reliability and the performance standards you expect from your RC buggy.
