Key Features

• 75-Tooth design with 48 Pitch specification — This is a smaller-diameter spur gear compared to standard options, specifically engineered to work with the compact drivetrain geometries of brushless stock motor racing setups. The 48 pitch rating ensures precise mesh with compatible pinion gears, delivering smooth power delivery and minimal drivetrain noise during operation.
• Optimised for 17.5, 13.5 and 10.5 brushless stock motors — This spur gear is purpose-built to work harmoniously with the most popular brushless motor sizes used in 1/10 scale racing. Whether you're running Team Associated's own brushless motors or compatible third-party units, the AS9650 delivers reliable performance without strain on your motor or ESC.
• Enables smaller pinion gears for finer gearing steps — One of the most significant advantages of this design is that it allows racers to use smaller pinion gears, which creates more granular gear ratio options. This means you can fine-tune your setup with greater precision, finding the exact gearing that suits your particular track, driving style and motor choice. Previously, some combinations simply weren't possible with larger spur gears.
• Moves motor forward for improved balance and handling — The smaller physical diameter of this spur gear allows you to relocate the motor forward in the chassis, shifting the weight distribution in a way that genuinely improves the driving experience. Better weight distribution means more predictable handling characteristics, improved cornering stability and a more responsive feel through all phases of driving—acceleration, braking and turning.
• Premium Team Associated engineering and quality control — This is not a generic spur gear. Team Associated maintains strict manufacturing tolerances and uses quality materials throughout their component range. You're investing in precision engineering that will outlast cheaper alternatives and maintain its performance characteristics over extended use.

Technical Performance

The AS9650 represents the intersection of practical engineering and racing necessity. At 75 teeth with 48 pitch specification, this spur gear sits at a critical intersection in the gearing world—large enough to provide smooth, reliable power delivery without excessive noise or vibration, yet small enough to unlock new possibilities in gear ratio selection that weren't available before. The 48 pitch standard is one of the most widely used specifications in 1/10 scale RC racing, ensuring compatibility across a broad range of vehicles and setups. The engineering behind this component focuses on material quality and machining precision; Team Associated spur gears are manufactured to extremely tight tolerances, ensuring consistent mesh with pinion gears, minimal backlash and maximum drivetrain efficiency. This translates directly to better acceleration characteristics, more predictable handling and reduced wear on associated drivetrain components. The smaller diameter means your motor sits further forward in the chassis, which in practical terms improves the weight bias of your vehicle—something that experienced RC racers understand as fundamental to competitive performance. Built from durable materials selected specifically for high-RPM, high-load environments, this spur gear is engineered to withstand the stresses of competitive racing, bashful track time and general recreational driving. The AS9650 is designed as a direct replacement or upgrade component for Team Associated vehicles, meaning installation is straightforward and fitment is guaranteed when paired with compatible vehicles and drivetrain components.
