At Trailer Gearbox, we believe that towing shouldn't be a workout. Our mission is simple: build tough, drill-powered trailer tools that eliminate the hassle of hand cranking — and make life easier for anyone who hauls.

Our Gearboxes are precision-engineered, torque-amplifying solutions designed to work hard, last long, and fit your lifestyle — whether you're hauling for work, heading to the next rodeo, or just getting things done on the weekend. Made from premium materials and built in the USA, every product we ship reflects our commitment to quality and real-world reliability.

Trailer Gearbox was born from experience. After years of manually cranking heavy-duty dump trailers, we set out to create a better way. What started as a need quickly became a game-changing solution — and today, we’re proud to support haulers, workers, and everyday trailer owners across the country.

We back our products with unmatched customer support and a no-nonsense warranty because we don’t just stand behind our Gearboxes — we use them too.
