Stemco’s automatic trailer tail

Updated Apr 23, 2018

Stemco's TrailerTail AutomaticStemco’s TrailerTail Automatic fuel-saving system is designed to deploy the company’s aerodynamic trailer tail automatically when the trailer reaches 35 mph, removing the need for the driver to get out of the cab to open it manually. The device is engineered to receive speed and direction signals from the company’s wheel-mounted TracBat Aero speed sensor. The system closes the TrailerTail when the truck stops or goes in reverse, helping to minimize component wear and tear and prevent damage to the device, trailer or dock doors, and if the trailer loses power, the TrailerTail will close automatically, allowing access to cargo. The system is compatible with both new trailers and as a retrofit for existing TrailerTail Trident models.
