AD-SP DRYER HEATER KIT

This is a heater and thermostat replacement kit for Bendix AD-SP, AD-IP, and AD-IS style air dryers. It prevents moisture inside the dryer from freezing in cold weather, which could otherwise block airflow and compromise the vehicle's air brake system. The kit runs on 12 volts and includes the heating element, thermostat, and necessary seals to restore proper cold-weather operation. You typically replace this when the dryer isn't warming up properly or a thermostat fault is diagnosed.
