Available Natural Gas Aftermarket Conversion Systems

This document and the attached spreadsheets below replace the “Guide to Available Natural Gas Vehicles and Engines” previously available on our website. The information contained here and also in the spreadsheets covers aftermarket conversion systems that consumers and businesses may purchase in order to modify new or used vehicles so that they can operate on natural gas. Some of these systems may be ordered directly through automotive dealerships when placing an order for a new vehicle. However, all of the systems listed here are aftermarket from the standpoint that they are offered as modifications to original equipment manufacturer (OEM) gasoline or diesel fueled vehicles. We plan to provide a separate listing of the growing list of OEM NGVs (e.g., Honda, GM, Chrysler, and Freightliner).

The information in the spreadsheets is organized by certified or approved light-duty and heavy-duty chassis vehicles, as well as by certified or approved heavy-duty engines. The individual sheets are further organized by OEM (e.g., Chrysler, Ford, or GM), model year, and engine size, so that persons interested in a conversion system for a particular vehicle may quickly locate it. All of the systems listed have been either certified or approved by the U.S. Environmental Protection Agency (EPA) or the California Air Resources Board (CARB).

Please do not contact NGVAmerica regarding the availability of aftermarket systems. NGVAmerica does not sell conversion systems or provide any services related to the installation of such systems. Please review the listings of available systems and also the websites of the companies who offer them. All of these companies are dealing with a large number of inquiries and a significant demand for NGVs, so please review all available materials before making inquiries about particular vehicles, systems, or engines.
