no, most toys have the torsion bar setup I believe. easy to just slap in a generic upper bag mount and make it work. the upper arms are on top of the frame, which makes it simmilar to the M2 in that aspect.
i finally checked out the link to see this picture and that was from Havoc... the one and only time i have seen ur truck in person and got to meet ya... were there any pics of the Bagged TB on 20's w/ the green flames in that issue of Sport Truck(i only get mini truckin and street trucks)
