Retrofit Device Verification Database

Welcome to the Verification Database. This interface was designed to assist the end user in finding a retrofit device that is potentially verified for their on-road or off-road engine.

While every effort has been made to correct any "bugs" that may arise; certain areas of the database may act differently on different internet browsers. If you come across any errors within the data or any "bugs" on the webpages, please contact the database webmaster with feedback or suggestions at We are aware that some content may be clipped off the right side when using the Microsoft Edge browser, therefore it is currently recommended that you use a browser other than Microsoft Edge to view the database.
