Snowmobile tracks are made of a rubber which can be crushed under the weight of the machine if the snowmobile is sitting on a hard surface. Because of this, the rear of the snowmobile needs to be supported when it is trailered. These spacers are made of heat-welded HDPE (High Density Poly Ethylene). They are easy to clean, extremely durable, and more than strong enough to support a snowmobile.
