Composite Engine Mounts (1 of 3) New composite engine mounts, the first of their kind. This high tech space age material consits of fiberglass and nylon. Under high temperature and pressure this material is injected into a custom tooled steel mold. The results are fantastic, yielding a product lighter and stronger than aluminum. A pair of these mounts weigh only 2 ounces. We are so confident of this new venture we guarentee them for life. Available in red, black, or blue.
