Moves the trucks to the upper side of your board for that super stanced out look. Now even with longboard wheels, you have to manual to turn since there's no lean other than the gangsta lean you exude by riding such a pimp skateboard. Don't kill yourself doing it. In my photos, the three white risers are a v1 model I'm not passing out because they're not as rigid as v2 presented here. One of the risers is a v2 riser in ABS, the white are in Taulman 618.Print in taulman, abs, or something very strong. Print with 4 outer perimeters at 50% or better. Cut less out of your board than you'll think you need to, it's better to cut a bit at a time than to cut too much and screw it up. Be careful, this thing can kill you.
