Superwinch Synthetic Rope Extensions are designed to give the user an extra stretch for their winch in case their winch can't quite stretch far enough. Superwinch Synthetic Rope Extensions are constructed from heavy duty SK-78 Dyneema. This heavy duty synthetic material provides the user with rope as strong as steel, but at a fraction of the weight. This makes Superwinch Synthetic Rope Extensions very easy to transport, store and bring in to action when it's needed. The Synthetic Rope Extensions are available in multiple diameters and lengths to suit whatever need arises.
