Hadley is a supplier of quality components and solutions for commercial vehicles, tractor-trailers, transit and shuttle buses, RVs, motor coaches, specialty vehicle markets, and associated aftermarket distribution. Hadley was the first market participant to develop the Freon-powered dual trumpet horn known as the Hadley horn in 1945, which helped it gain market prominence. Later in 1960, it launched new product lines, including vacuum compressors and leveling valves for luxury passenger vehicles. Over the next decade it became the market leader in the luxury passenger car market for these products. Hadley then leveraged its expertise in air management to introduce a height control system for commercial vehicles in 1985. Hadley's ability to continuously innovate and cater to customer requirements enabled it to launch the SmartValve product, a one-stop solution for reducing effort and injury to drivers and improving fuel efficiency of class 8 trucks and tractor-trailers in North America.
