We are engineers not only by trade—but also by heritage.
Accomplished engineer George Sturmon founded ATRO in 1987 after realizing that truck torque rods were a quality problem because the rubber bushings were failing. The heavy-duty trucking industry requires equally heavy-duty parts, and George knew he could engineer a better solution.
So, he designed a way to replace rubber with his own custom blend of polyurethane to make torque rod bushings that last longer and perform better. Today, ATRO has grown to a team of over 100, and from a handful of products to more than 1,000. Our engineers custom design each of our products based on what purpose the part serves: load-bearing, dampening, transmission, shock absorption, or stabilization.
