The KO Propo RSx3-12 Upper Case acts as a direct replacement when the original servo top becomes worn or damaged. It is made to restore housing alignment and protect internal components so your RSx3 servo can continue to perform on the track or trail.
This upper case fits the KO Propo RSx3 servo family and is intended as a drop-in replacement for that series. The shape and mounting points match the RSx3 layout to simplify installation and reduce the need for modifications.
Swap the RSx3-12 Upper Case if you notice cracks, stripped screw bosses, or loose gear alignment. Replacing the top case is a cost-effective way to extend the service life of a working servo without replacing the entire unit.
