The ATRO Difference

Would you be surprised to learn that right in the heartland of America is where the best replacement parts for truck, bus and trailer suspensions are manufactured...for all-makes?

True! - ATRO Engineered Systems has been hammering out the most advanced polyurethane OEM and aftermarket parts out of Sullivan, Missouri since 1984!

ATRO has over 20 international patents on parts design, engineering and polyurethane development. ATRO polyurethane is made to fit the job. Trucks using our torque rods, bushings and mounts may carry 4 or 5 different types of our polyurethane (to match rebound, energy absorption and elasticity requirements). We even supply the US Army’s armored humvees and tank carriers with highly developed component parts.

The same advanced technology is used in the manufacture of our precision parts for all-makes, including custom replacements, outlasting competitors rubber-based equivalents by 3-5 times or longer. That means less downtime, less repair and replacement costs.

And, to top all that, ATRO has the most comprehensive parts warranty in the industry.

ATRO is An American Company!
