Arizona offers hundreds of miles of public highways and country roads as well as some of the best private 'proving grounds' with strictly controlled surfaces such as fixed cobblestone, Belgian block, steep grades, speed bumps and high speed oval course. Don't let the dryness fool you because within 15-20 miles of our headquarters, there are two lakes available for water testing.

WHY ​arizona

​Stacy Testing is located in central Arizona, which has one of the most extreme climates for vehicle and component testing in the world.  Climates range from hot-high ambient at lower elevation to cool temperatures at high altitude, making this area of the country one of the best locations to test products in worst case conditions!
