The KO Propo 35546 aluminium gear is built to be a durable replacement for the BSx2 Response servo series. Favoured by builders who run rough terrain or frequent sessions, this metal gear stands up better to wear than factory plastic gears. Its construction aims to keep your servo working reliably under sustained use.
Aluminium offers improved wear resistance and stable tooth engagement compared to softer materials. The KO Propo 35546 helps maintain consistent servo action and reduces the need for frequent gear replacements, making it a sensible upgrade for heavy-duty use.
Specifically matched to the BSx2 Response servos, the gear installs without special adaptations. The direct-fit design keeps service simple so you can complete repairs trackside and return to running quickly.
