The two initially specialized in the repair of 1984-87 Lincoln Continental and Mark VII Air Suspension systems. The grassroots success of father and son was soon echoed throughout the state of Florida. Soon, it was necessary to become accessible to the entire state in a central location. Accordingly, ARNOTT was relocated to Orlando, Florida in 1994 because of the city's geographic locale and commercial traffic. As the company grew, and the name Arnott had become synonymous with air suspension specialists, founders Adam and Donald Arnott vowed to maintain their purpose: to provide their customers with quality products with unparalleled customer service and support. The small team of 10 employees worked tirelessly on assuring the quality of each remanufactured part before distribution. They then researched and tested existing models of air suspension products and discovered various ways in which to improve on an existing idea. And so they developed their own newly manufactured air suspension products, proudly marked with the Arnott family name. Now the products and services of ARNOTT were even more unique, and ensured the total satisfaction and safety of all customers. Indeed, word did travel fast, and in no time the small company had matured and thrived as a national leader in the manufacturing of air suspension products. Today, ARNOTT has literally revolutionized the air suspension industry, providing world-class parts and service to automotive professionals and auto owners alike, not only nationally, but also globally. In addition to the after-market suspension products produced for vehicles with factory-installed suspension systems, we have applied our extensive knowledge and expertise to the creation of our newest series of products - complete computerized suspension systems that are custom engineered for most full-sized trucks.
