This spur gear is an RC-scale replacement part specified for BD5 chassis use and carries a 95T tooth count as indicated by the model name. Its role is limited to the drivetrain of 1/10 on-road models, where tooth count and mesh influence final gear ratio and vehicle response.
Compatibility is restricted to BD5-series layouts, so verify mounting pattern and center distance against your existing gearbox before installation. Because tooth count directly changes gear ratio, fitting this 95T spur will require selecting a matching pinion to obtain the intended final ratio.
Installation notes: check gear mesh with the motor pinion at idle, ensure backlash allows free rotation without binding, and re-torque mounting hardware after a short run-in. Regular inspection for wear and proper lubrication will keep gear engagement consistent during tuning sessions.
