Your Dedicated, Quality Transportation Components Supplier
APT Corp. is the leading supplier of durable components for the heavy-duty truck and trailer
industry. A family owned business founded in 1982 in Cincinnati, Ohio, APT Corp. is dedicated
to quality in every aspect of business, from the high quality material used for all products to the personalized, professional customer service and commitment to competitive pricing.

Founder, William Underwood originally started the company as an Importer of Transportation equipment/components. As the demand for high-quality, specialized components grew, William
Underwood moved the business to Dayton, Ohio. In 1986, William Underwood’s son, Jeff joined
the venture. In 1990, the company-owned tooling and resources were brought back to the
United States and solid relationships with domestic producers were developed.

Today our goal is simple: provide the best products, with the best service at a price that is
competitive. We fight price increases using every method at our disposal, except one – quality.
And we’ve been successful, as many of our prices are the same as the day we opened or have
risen a fraction of the inflation rate. Some of our items are even less expensive then they were
when we began operating.
