The California Air Resource Board (CARB) has restricted Custom Chrome and its Vendors from sales and shipping of the following items to California residents. In efforts to keep our Customers educated and in compliance this list will be updated regularly.
What this means for the Revtech site is we will not be able to ship anything that modifies your EPA system. Motors, Pistons, Cams, Bore Kits etc...
Web Orders: This website does not allow restrictions of this manner. Orders containing these items being shipped to CA, will be removed by Custom Chrome before shipping and the money refunded.
See this document (PDF) below which lists all items that cannot ship or sell to the state of California.
