ZeroTouch Deployment System

ZeroTouch technology connects directly to the trailer’s built-in ABS ECU to automatically deploy the TrailerTail® rear fairing when the vehicle reaches 35 mph. It requires no additional wiring to the J-box, which means fewer parts, faster installation and easier maintenance.

ZeroTouch is compatible with OEM trailers that use Meritor WABCO InfoLink ABS ECU systems. Fleet owners who want automatic deployment but do not have this type of trailer can still use STEMCO’s radar-based AutoDeploy system.

There are four TrailerTail® models available for use with ZeroTouch technology:

1) TrailerTail® 4x4 w/ ZeroTouch for dry van trailers
2) TrailerTail® 4x4 w/ ZeroTouch for refrigerated trailers
3) TrailerTail® Trident w/ ZeroTouch for dry van trailers
4) TrailerTail® Trident w/ ZeroTouch for refrigerated trailers
