This upper case is a direct replacement built to fit KO Propo 35031 - RSx12 servos with precision. It offers a reliable shell to protect internal parts during off-road runs or everyday driving.
Targeted to RSx12 dimensions, the upper casing holds components firmly in place and helps prevent premature wear. Using genuine parts keeps mounting and fitment exact for predictable servo behavior.
Regularly replacing worn servo housings with authentic KO Propo components like the 35031 helps preserve steering and throttle accuracy. This part suits modelers who want consistent performance from their servos.
