The KO Propo 35546 aluminum gear is a precision replacement made for the BSx2 Response servo series. Built for long service and smooth tooth engagement, this part suits hobbyists who want improved reliability and control in their RC cars. Constructed from quality aluminum, it resists wear better than stock plastic gears and is well suited to regular track use or routine maintenance.
Aluminum gears offer a robust yet lightweight option that improves longevity without adding unnecessary bulk. The KO Propo 35546 leverages those qualities to reduce play and sharpen servo response, giving crisper steering and throttle feel. It is a practical upgrade whether you focus on lap consistency or keeping spares on hand.
Made to match the BSx2 Response series, this gear installs directly and requires only standard tools. Compatibility with KO Propo servos means you can swap it in without modifying the servo housing, reducing repair time and getting you back on the track faster.
