Xcessive Lower Radiator Cushion for Lexus IS300

The Lower Radiator cushion is an important part when it comes to vibration absorption and electrolysis isolation. They seem like such a simple part, but they're quite important. Vibration and electrolysis will degrade the radiator and affect the coolant and how it carries electrical currents through the engine and radiator. Isolation is key! If your lower mounts are hard or missing, replace them with our new Urethane Mounts!
