This spur gear is an RC-scale replacement part specified for BD5-compatible chassis use and carries a 95T tooth count as indicated by the model name. Its role is focused on the drivetrain of 1/10 on-road cars, where tooth count and mesh tuning directly influence final gear ratio and vehicle response.
Compatibility is limited to BD5-series layouts, so confirm your gearbox mounting pattern and center distance against the original parts before installation. Because tooth count changes the overall ratio, fitting this 95T spur requires selecting a matching pinion to reach the intended final ratio and safe operating RPM.
Installation notes: set the gear mesh with the motor pinion at idle, allow slight backlash to prevent binding, and re-torque mounting screws after an initial run. Regular checks for wear and correct lubrication will maintain consistent gear engagement during tuning sessions.
