Prothane mounts are designed to limit unwanted movement and control torque thereby putting more power to the wheels and also reducing the chance of breakage. You will notice performance gains on the street or track with their almost indestructible mounts. Prothane motor and transmission mounts are strong and tough like a solid metal mount without the vibration and noise. All mounts are very durable and resistant to oil, chemicals and road contaminants that deteriorate rubber mounts. Prothane mounts feature application specific engineering. In other words they are not a universal ''one fits all '' application. This will insure you to get a maximum benefit from a Prothane product. Where applicable, mounts feature internal ''run safe'' interlocking engineering or specially designed mechanical interlocking steel inserts. Certain mounts also feature an innovative mounting method which allows one mount to fit multiple applications without compromising fit or quality. Prothane mounts are manufactured of the highest quality specially formulated polyurethanes. In a nut shell Prothane will provide you with the performance and value you demand.
