The KO Propo 35523 Metal Gear Set replaces the weak plastic gears in PDS-763 and PDS-764 servos, giving a more robust drivetrain for cars and buggies that see heavy impacts. Expect improved gear engagement and fewer service intervals when running hard off-road.
Metal gears resist chipping and deformation better than plastic, which keeps steering and throttle responses predictable under load. This upgrade is particularly useful where sustained torque and frequent gear changes are common.
Specifically made for KO Propo PDS-763 and PDS-764, the gear set installs with routine servo service steps. Check spline fit, set correct mesh, and use a light coating of grease to protect contact surfaces in dusty or wet conditions.
