The Husky Towing Quest Proportional Trailer Brake Controller (31899) delivers smooth, responsive braking by mirroring the braking action of your tow vehicle in real time. Built around an advanced inertial accelerometer, the Quest provides confident stopping power for a wide range of towing applications, from light utility trailers to fully loaded equipment and RV trailers.

Designed to control 2 to 8 electric trailer brakes (1–4 axles), the Quest features automatic leveling, allowing flexible mounting without sacrificing performance. Fully digital gain and sensitivity controls make setup fast, repeatable, and easy to fine-tune, even when switching between empty and loaded trailers.

An easy-to-read digital LED display shows power output on a clear scale from 5 to 99, while on-the-fly sensitivity adjustment with five preset response levels allows instant tuning as road or load conditions change. With its compact size, flexible mounting options, and quick installation time, the Husky Quest is a dependable proportional brake controller for everyday towing and work-duty use.
