Over 60 years of engineering milestones for Gale Banks Engineering founder and president Gale Banks began at age 14 with an engine teardown of his mother's '31 Ford Model A that resulted in an increase of more than 40 horsepower. Just two years later, in 1958, Gale was officially in the engine business, first in Lynwood, California, then in San Gabriel. He remains the hands-on president to the 200-employee-strong manufacturing and engineering complex that today occupies 12 acres in the San Gabriel Valley town of Azusa. Gale Banks Engineering is known far and wide as the premier designer and manufacturer of power-enhancing products for diesel- and gas-powered trucks, motorhomes, and sport-utility vehicles. Since the 1960s, Gale's futuristic high-performance engines have broken new ground while shattering world records. His marine engines propelled racing boats to national and world championships, and his marine engines were chosen by the U.S. military. After decades of racing, Banks Power is still the only company to have set records at Bonneville in both automobile and truck classes.
