Technical Performance

The Associated CR12 Gearbox and Motor Mount represents precision engineering designed to handle the demands of competitive and recreational RC car UK use. This component is manufactured from durable materials selected to withstand the forces generated during acceleration, cornering, and deceleration whilst maintaining precise tolerances that allow smooth gear rotation and reliable motor mounting. The gearbox housing portion of this assembly is engineered to accept standard CR12 gears and ensure they rotate freely without binding or excessive play, which would otherwise result in power loss, increased wear, and potential mechanical failure. The integrated motor mount portion is designed to hold your CR12-compatible motor in perfect alignment with the transmission, ensuring that power is transferred efficiently to the drivetrain without vibration, misalignment, or slippage. The assembly's construction allows it to handle the torque outputs of brushed and brushless motors commonly used in CR12-based builds, making it a versatile solution whether you're running a stock motor or a high-performance upgrade. By maintaining correct gear mesh angles and motor alignment, this component ensures that your RC car's acceleration response remains crisp, your top speed remains consistent, and your overall driving experience remains predictable and enjoyable. The precise engineering also reduces noise during operation and extends the lifespan of your gears and motor bearings by minimising friction and side loads.
