Our parts sales experts are here! Let the experts at Carl Haas Auto help you find exactly what you are looking for. CONTACT US Racing gearboxes, chassis and damper sales. Thank you for allowing us the opportunity to continue to give you the service you have come to expect for over 50 years! Carl Haas started his parts business in 1960 filling a need for quality race cars and parts in the rapidly growing professional and amateur racing industry. Since the very beginning our goal has been to deliver nothing but the best for our customers. Carl introduced a revolutionary program called the Haas FAS-PAC service which guaranteed delivery of parts in less than 24 hours anywhere in the USA. This was long before any of the express delivery companies that we all take for granted now. Carl also did the unheard of and started taking used race cars as trade-ins on new cars. These two programs helped the racing industry grow immensely in the 60's and 70's and we still strive to deliver the same quality parts and service be it a single part for a club racer or a complete trackside parts program for an entire series. Many of our parts are marked “Get Quote”. With our website, you build your order and submit it to us. Once we review it, we will contact you with the order total (including shipping costs and individual parts pricing) and collect payment information. 500 Tower Parkway Lincolnshire, IL USA 60069 Phone: (847) 634-8200 Fax: (847) 634-8208 © 2005 - 2021 Carl Haas Automobile Imports, Inc.
