Abstract
A skid frame for a snowmobile is disclosed including a generally planar skid surface extending between front and rear idler wheels. The front and rear idler wheel are offset from one another and define a longitudinal direction. A track encircles the skid frame having the skid surface positioned over a center of the track such that a major longitudinally extending portion of the track that is coextensive with the skid surface has first and second unsupported lateral portions on either side of the skid surface. The first and second unsupported lateral portions extend in the horizontal direction at least 25 percent of a width of the track. A suspension arm member may mount the skid rail and include mount portions for mounting to a tunnel and spanning a distance at least twice the width of the longitudinal beam.

A skid frame assembly comprising:
- a skid rail, the skid rail comprising:
- a first wear strip including an inner edge and an outer edge;
- a second wear strip including an inner edge and an outer edge, wherein the outer edge of the first wear strip is positioned a first distance from the outer edge of the second wear strip;
- and
- a suspension arm member including a first mount portion pivotally secured to the skid rail and second mount portions configured to secure to a chassis of a snow vehicle, the second mount portions span a second distance that is at least twice the length of the first distance, wherein the first wear strip and the second wear strip are positioned between the second mount portions.
