About ATRO

Not all brands in the heavy-duty truck parts market care about your productivity and business uptime the way ATRO does. ATRO Engineered Systems aims to make your fleet spend more time on the road and less in the repair shop or garage by producing polyurethane truck components that consistently outshine the competition in quality, performance, and longevity.

ATRO was born in 1987 out of an engineer’s realization that a truck torque rod’s malfunction is a quality issue because it is caused by failing rubber bushings. That accomplished engineer, named George Sturmon, knew that the heavy-duty truck industry could use heavy-duty parts, and he could develop a better solution.

The desire to address the torque rod’s problem with an ultra durable solution became George’s driving force in devising a way to swap rubber with his invention—a custom-made polyurethane blend used to form high-quality torque rod bushings that last longer and get the job done right.

ATRO managed to thrive despite the steep industry competition, and it has grown into a team of more than 100 people with a product portfolio of over 1,000 ATRO parts. These high-caliber products are living proof of the company’s unparalleled commitment to performance, precision, and productivity.

ATRO Parts

ATRO is serious in its dedication to keeping your fleet on the road. The best proof of that is the longer-lasting ATRO parts developed to help your business save money by keeping the truck’s downtime at a minimum. The engineers and parts specialists at ATRO understand that each part is made to do a specific task while withstanding stress, abuse, damaging environmental elements, and regular wear. That is why each ATRO product is custom designed by skilled engineers according to the part’s functions—shock absorption, dampening, stabilization, load-bearing, or transmission.

ATRO parts are made in the U.S.A., so they guarantee excellent craftsmanship and reliable functionality. They repeatedly pass rigorous tests to ensure durability and peak efficiency. Manufactured with custom polyurethane blends, each of these parts are highly resistant to chemicals and are more durable than the competition.

Torque Rod

ATRO would not be recognized as a global leader in torque rod technology for nothing. This company is dubbed as such because of its stronger, better-performing torque rods, which prove to be lasting and economical solutions to the issues posed by torque rod assemblies with rubber bushings. Standard rubber bushings tend to gather dust, windup, stretch, and breakdown over time, causing noise, vibration, various performance issues, and even premature failure.

The torque rods from this brand feature rotating pin technology, making these components both versatile and durable. With these torque rods, you can say goodbye to those days when you get frustrated due to incorrect clocking and improper bushing installation. These components are available in various configurations, and they come with the brand’s exclusive free-rotation design that makes installation an easy feat.


ATRO also supplies the industry with innovative and best-in-class suspension components for trucks, buses, trailers, and agricultural and military vehicles. These parts showcase patented design and polyurethane construction, making them ideal even for heavy-duty suspensions. Like other ATRO products, these first-rate suspension parts are specifically engineered to be highly resistant to chemicals and contaminants like grease, road salt, acidic cleaning solvents, diesel fuel, oil, and hydraulic fluid.

Built to OEM specifications, ATRO suspension parts directly replace the factory-original components and are proven to match or exceed the performance specifications of original units. The list of ATRO parts for the suspension system includes:

  • Bump stops
  • Spring eye bushing kits
  • Spring eye shackle kits
  • Spring hanger/bushing kits
  • Polyurethane shims
  • Bushings


With ATRO backing you up, you can move forward without fear. Steer King and ATRO have joined forces to provide the industry with premium-quality steering system parts that are long-lasting and easy to install. With the brands’ shared legacy and shared commitment to take your trucks out of the shop, you can expect minimal business downtime and an improved bottom line.

Steer King offers durable, no-ream King Pin kits that are high quality and precision-engineered. The components in these kits are precision machined and 100% inspected for accurate dimensions. ATRO provides customers like you with bronze kits, steer spiral kits, axle sleeves, and installation tools.

Trailer Parts

ATRO understands how important trailers are for your business. That’s why it develops a range of trailer replacement parts and accessories to help you in servicing and restoring your trailer’s full functionality. The critical parts you need for your trailer should also come with ATRO’s badge. From trailer suspension parts to the various components in your trailer’s bumpers, you can find exceptionally durable and easy-to-install ATRO replacement units for those. This brand also manufactures class-leading trailer torque rods and 5th wheel components that exceed the performance and quality specifications of the original.

Underhood/Cab Solutions

Make sure your engine, transmission, and exhaust systems will perform well regardless of the operating environment by providing them superior-quality ATRO exhaust and engine mounts. These mounts are also available as part of a kit, along with the necessary hardware for trouble-free installation. Besides mount kits, ATRO also produces mount assemblies and insulator kits. Also included in this ATRO product offering are hood latch, hood catch, hood rest bracket, spike grommet, bumper, mount pivot bushing, roller, hood support, and many other hood components.

High-Temp Products

Some ATRO parts are high-temperature products. They take great pride in being the only high-temperature poly on the truck parts market. Since they can withstand scorching heat, these products perform well even in the severe conditions of EGR/SCR engines. ATRO’s high-temperature engine mounts, for one, maintain their structure, stability, and flexibility while minimizing vibration in the cab and controlling unexpected shifting of loads. The high-temperature product line from this brand includes:

  • Cab mount
  • Air cooler mount kit
  • Exhaust mount bushing
  • Radiator mount
  • Insulator kit
  • Shock bushing
  • Transmission mount
