Prior to contacting us, please note:
The SMC crew is small, so we do our best to have the answers to the most common questions we get on the website. Please visit our Information Center for details about shipping, payment options, warranties, returns, and more.
For international orders, please visit our Shipping – International Orders page prior to contacting us. You will find information about our international shipping policies as well as a form like the one below for international order inquiries.
We post up to date stock quantities on the category pages in blue and each product page in flashing red.
If you are wondering if a part will fit your application, please contact your GM dealer with your VIN to verify correct part fitment prior to purchases. We are not a GM dealer and will simply direct you to contact one.
All computers will require programming to your vehicle VIN#. We do not program vehicle computers, but can recommend a couple bench top programmers other than your GM dealer for some of the computers we sell. If you would like a recommendation on a programmer, please mention this in your order notes at the time of purchase and we will include a list with your order.
Finally, and most importantly, please verify that the email address you enter is typed correctly prior to sending. If the address is incorrect we are not able to respond to your message.
Store visits by appointment only. Please email ahead and we will be happy to accommodate your request.
