The KO Propo 35546 aluminium gear is a competition-friendly replacement part for the BSx2 Response servo series. Engineered to offer improved tooth integrity and long service life, it is a sound choice for racers and dedicated modellers seeking consistent control. The aluminium construction offers a notable step up in wear resistance over standard gearing materials.
Metal gears reduce deformation under load and help maintain tighter gear mesh, which can translate to more predictable servo movement. The KO Propo 35546 aims to provide cleaner feedback and steadier handling so drivers can trust their inputs during precise manoeuvres.
Designed to fit the BSx2 Response servos, this gear installs as a direct replacement with no special alterations. That makes it convenient for routine servicing or when you need a reliable spare on race day.
