Hello, I was curious to know if the extreme bone shakers will fit on a rocker? I'd love to have the hell raisers or even the street sweepers but according to the website they won't fit. I might add i think the bone shakers would look fitting on a rocker but not 100% positive about that. If they do fit I'm thinking I would also need torque cones? I'm not seeing them on the website for some reason though.
