Abstract: A tapered short tunnel for use on a tracked vehicle, such as a snowmobile. The tapered short tunnel has a tapered distal end having a width less than a width of an endless track used on the snowmobile. This tapered portion reduces the snowmobile from catching or grabbing snow in a snow trench, thereby enabling the snowmobile to traverse deeper snow.

Abstract: A snowmobile comprises a chassis with a front portion and a tunnel, and a power train unit supported by the chassis. The snowmobile further includes a plurality of ground-engaging members cooperating with the power train unit to operate the snowmobile. The plurality of ground-engaging members includes a pair of front skis and an endless track assembly. The snowmobile also includes a front suspension operably coupled to the pair of front skis. The snowmobile also includes a rear suspension operably coupled to the track. The rear suspension includes slide rails and track sliders for engaging the track. The track sliders are comprised of a first and second retention members for coupling with the slide rail. The retention members are comprised of a plurality of recesses where material is removed for light weighting.

Abstract: A tunnel is configured to cover at least a portion of an endless track of a snow vehicle. The tunnel has a top plate extending longitudinally. The top plate has a first flange extending from a first side edge and a second side flange extending from a second side edge. The tunnel further has a first sidewall coupled to the first flange extending generally parallel with the first flange. A second sidewall is coupled to the second flange extending generally parallel with the second flange.
