This skidplate will replace the flat delrin plate that comes in every GCM Skeleton Kit. This plate drops the skid and Tcase by about 1/4 inch and keeps the same link position so the wheelbase doesn't change at all. There's already holes in the plate for the GCM Tcase, but many have used this plate for a RC4wd Helios 2spd case install in the Skeleton chassis as well.
Before installation, clear out the lower link holes with a 3/32 drill before using M3 screws for attaching the links to the skidplate.
