WELCOME To 1990Suburban.com + ONLINE'S LARGEST collection of Converted SUBURBANS!

This is a personal web site dedicated to my 1990 Suburban Gran Prix 4x4 and other 7th Generation Suburbans with conversion packages. Suburban conversions were typically done by van conversions companies and usually cost $6,000 to $13,000 on top of the purchase price. Indiana (where the Gran Prix was built) was the state with the most companies setting up shop with over 60 companies doing van and suburban conversions. Check out the Gran Prix Page. For a complete list of all the conversion companies I have found that did Suburbans click here or click on an image below. Enjoy!!

SUBURBAN CONVERSION COMPANIES for 7th Generation Suburbans

In my search to learn more about the Gran Prix Conversion from Truk-Mate, I have found many other van conversion companies that also converted Chevrolet and GMC Suburbans in the 80's and 90's. My research started in 2014 and I'm always adding new finds to this online collection. I believe I have the only web site dedicated to converted Suburbans. I have decided to focus on 7th Generation Suburbans only, which covers 1973-1991. All that I know about these conversion companies I have posted on this site so if you are looking for specific information, wiring schematics, production numbers etc, I probably won't be able to be of much help but as I come across this information, I will definitely post it on each specifc conversion company page. Plese note that pretty much all of the Suburban you find on this site came from classifed sites like Ebay, Craiglist and sometimes existing owners. Most of these Suburbans were for sale at one point when I found them but this site is not affiliated with these Suburbans or their owners in any way so please don't contact me asking me about them as I have no additional information.
