A modified truck piece for attachment to a board surface such as a skate board. The truck has two pair of extended ridges each pair having an upper and a lower ridge and each pair running the length of the truck. Skidding pads are attached to the ridges and offer a protective surface covering for the ridges and thus allow the skateboard to be tilted (rolled) to one side or the other with safety. A channel in the bottom of each truck half allows an in line set of wheels to be attached to the underside of the truck piece. The pads may be replaced or reversed as needed.
