A cleat is disclosed for mounting on the outer surface of an endless belt used as a track for a snowmobile. The cleat comprises a relatively narrow, elongate, essentially planar fin whose elongate length is no greater than about ten centimeters and whose width is no greater than about 4 centimeters. A relatively narrow, elongate, essentially planar flange extends along an elongate side edge of the fin. The flange has an elongate length which is substantially the same as the length of the fin and a width which is no greater than about 4 centimeters. An opening through the flange is used for attaching the flange to the outer surface of an endless belt used as a track for a snowmobile. A plurality of sharp projections extend from the broad side of the flange which faces away from the planar fin. The projections are adapted to engage the outer surface of the endless belt when the cleat is attached to the endless belt. The fins slant with respect to the flanges such that an included angle is formed between the fins and the flanges, with the angle being between about 30 and 80 degrees. The fins provide improved traction for the track of the snowmobile upon which they are installed. The fins simultaneously provide lift to the track of the snowmobile thereby avoiding the tendency of the snowmobile to dig into and bog down in deep snow.
