More About Performance Engine & Transmission Mounts
Stock drivetrain mounts are designed to keep everything as tight as it can be without causing noise, vibration, or harshness. Unfortunately, that means they sacrifice some rigidity for comfort. Upgrade to stiffer or solid drivetrain mounts for better engine response and less deflection!
