That's a sledgehammer mod done by TX-Tuning in Germany. Their website is here:
http://tx-tuning.com/I doubt they list the mod on their site anymore. As I recall, the mod required the use a 2002 VF body only. It might be possible to do it to other bodies that have almost no milling on them, but, since most, if not all stock bodies after 2002 have milling, those bodies would be much more difficult to find a spot to mount the ram without having the necessary screw holes either strip out or the screws stick too far in and interfere with the bolt or hammer.
