    Abstract: A grouser structure for use on an outer surface of a continuous track belt to provide traction and shock absorption, the grouser structure including a grouser body that defines a grouser chamber and a spline element positioned within the grouser chamber. In one preferred embodiment a shock absorption gap is formed between the inner chamber peripheral surface and the outer spline peripheral surface. In another preferred embodiment the base of the grouser body is solid or contains other structure to prevent the first body side leg and the second body side leg from spreading. In yet another preferred embodiment the spline element is a solid reinforcement spline element. In still another preferred embodiment the spline element is associated with an extension section to which an ice cleat may be functionally attached.
