Aspen Core Features

  • Experienced Design … All of our products are meticulously designed by Aspen engineers with over 240 years of combined trailer engineering knowledge. Our product line is driven by advanced technologies, strategic vision, and the diverse transportation challenges our customers face.
  • “Flex Frame” Design … All of Aspen’s trailer frames are designed with flexing in mind which allows the frame to flex in all of the right places to allow frame deflection without breaking in key areas of the trailer. The flexing is made possible by industry driven, intelligent design and the use of high grade steel (100 – 130 KSI) to ensure many years of low maintenance trailer use.
  • A Culture of Quality … Quality is the cornerstone of all we build. It’s present through every phase, from customer consultation and detailed trailer design to premium brand name material selection and manufacturing.
  • Customer Satisfaction … With a history of designing trailers for custom applications, we pride ourselves on being able to communicate with our customer to understand their specific transportation challenges.
  • Low Maintenance and long life … One of the reasons customers pay more for Aspen trailers at resale is the proven long life and low maintenance Aspen trailers. You can be assured that when you buy an Aspen, it will provide more hours of service for your fleet and ultimately Haul More over its lifetime.
