Metallic clips are provided on the endless track of a snowmobile equipped with one or more elongated slide runners forming part of its suspension system. The clips are formed with a first portion adapted to be slidably and frictionally contacted by the slide runners during rotation of the track and with a second portion extending slightly above profiles integrally formed on the outer surface of the track so that heat generated as a result of the sliding friction of the runners on the clips is transferred directly to the snow or ice over which the snowmobile travels so as to cool the clips.

1. A track for use on a snowmobile having a suspension system equipped with one or more elongated slide runners, said track comprising:an endless body having an outer surface with transverse ground engaging profiles spaced longitudinally thereof and an inner surface adapted to receive, on the lower run thereof, said slide runners of said suspension system; said track including one or more rows of longitudinally spaced metal clips secured to said body of said track; and each said clip having a first flat portion extending substantially in the plane of said inner surface and so disposed thereon as to be frictionally contacted by said slide runner, and a second portion extending above said outer surface of said track so as to contact the ground over which said snowmobile travels; wherein each said clip is formed of a slide contacting lower part including said first flat portion and of a ground engaging upper part including said second portion, said lower part having hook ends engaging corresponding hook ends on said upper part to inter-engage said parts to one another, whereby heat generated by frictional sliding contact of said slide runners on said first portion of said clip is thermally transferred to the ground being of a temperature lower than that of said heat generated by said frictional sliding contact of said slide runners on said clips.
