About Us

    With direct access to the widest collection of in-stock performance parts and accessories for the majority of cars, trucks, Jeeps, and SUVs from over 200 brand-name vendors, Customdiag.com is devoted to the automotive enthusiast. 

   We only sell things that are in stock, provide free shipping* on the majority of orders, and never impose handling costs because of this combination, which gives you, the customer, a distinctive shopping experience. Our executive team and skilled personnel have years of experience in the speciality automotive aftermarket, and we have worked with some manufacturers for as long as 8 years.

   So, how does this affect you? It is the peace of mind that comes from knowing that you are working with genuinely knowledgeable, hands-on Americans who are passionate about automobiles, who have access to the parts' original equipment makers directly and the knowledge and expertise to give you the finest possible customer service.

   We do not run any other websites that offer sporting goods, hardware, books, music, or anything else. Specialty automotive parts are the focus of our company, and we intend to keep it that way.

   Please send us an email at support@customdiag.com if you have any suggestions for how we may better serve you. Happy modding and we look forward to hearing from you.
