Our polyurethane truck parts consistently out-perform for quality and longevity.
Engineering
Polyurethane is stronger than rubber, and wears less with reduced friction at the surface. With ATRO, you'll have a longer life on your parts—and less downtime for your fleet.
Quality
ATRO polyurethane parts are resistant to oil, grease, salt, and abrasives. When compared to rubber parts, ATRO Parts are more durable and reliable and reduce lifecycle costs.
Products
ATRO’s engineering team has designed specific polyurethane compounds to optimize performance on each part—including our exclusive High-Temp parts.
