Abstract: A pair of elongated housings are positioned generally parallel to each other for connection of a wheel to a vehicle. An elongated member comprising a plurality of rollers is positioned within each of the housings. Spring biasing urges the elongated members downwardly, with the spring biasing absorbing shocks received at the wheel and conveyed to the elongated members, causing movement of the elongated members within the housing. The series of rollers on each of the elongated members traverse the housing to reduce friction between the housing and the elongated member as the elongated members traverse the housing. At least one vehicle wheel is mounted to the elongated members.
