ABSTRACT:
A snowmobile track suspension subframe of the slide rail type carries a track drive axle at its forward end. Such axle mounts both the track drive sprockets and the driven sprocket of a track drive chain assembly so that the entire track suspension subframe assembly, including its forward drive end, is capable of movement independently of the main frame.
