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.

Customer Testmonials

Engineered for Precision, Performance, and Productivity.

Different parts do different work, while exposed to changes in stress, strain, and the environment. Other companies use just a single blend of polyurethane to make all of their heavy-duty truck parts. At ATRO, we know it takes more than that to get the job done right.

We've designed and developed custom polyurethane blends to precisely solve this problem. The result is industry-leading products that deliver precision, performance, and productivity.

Less Time in the Shop, More Time on the Road.

At the end of the day, it is all about productivity. Trucks in for repair means disruption to your service, your company, and your customers. Leading industry experts report that it costs $1,000 for each day a truck is off the road for service.

Labor costs, parts costs, lost revenue and frustrated customers—they add up in a hurry, and then compound over the life of each vehicle in your fleet.

Our team is committed to keeping your trucks on the road, and out of the repair shop. To learn more about how ATRO’s longer-lasting parts can save your organization time and money, access our Where to Buy map to find a Dealer/Distributor in your area.
