the volcano sv has pillow ball suspension, so it would not make sense to spend the extra $100 or more to turn it into an ultra wide tsunami. not only will you have to change the a-arms but you will need the ultra wide dog bones, c-hubs, c-hub carriers, axle shaft and various other parts only to und up with an inferiour suspension system not to mention expensive to replace aluminum arms. there is no kit, but a few have custom made there own a-arms to work with the volcano pillow ball suspension.
