The Prothane motor mount insert for 2005–2006 Chevy Cobalt SS applications replaces the original insert to firm up engine placement and reduce movement. In black, this direct-fit insert helps reduce vibration and driveline lash during hard acceleration or deceleration, restoring a more controlled feel to the engine mounting on the specified Cobalt SS models.
