Established in 1946 after World War II, the Hellwig brand is committed to engineering top-quality sway bars and suspension products for individuals and companies who won't settle for anything but the best. The company's journey began when founder, Rudy Hellwig decided to manufacture the exclusive Hellwig Helper Springs to assist cars and trucks that sag when under heavier load. These helper springs greatly assisted in improving the setup, resulting in better handling and reduced chances of accidents.

Since its founding, Hellwig has remained a family-owned business with all of its steel products manufactured in California's Central Valley. Through the years, Hellwig has consistently reinvented itself to produce progressive suspension systems that improve a vehicle's efficiency in handling loads and controlling sway. The product range includes anti-sway bars, helper spring kits, adjustable end links, air spring kits, and many others for both aftermarket and OEM applications. Guaranteeing innovations that adhere to today's demanding quality standards, Hellwig is ISO 9001:2015 and ISO 14001:2015 certified.
