The Gran Prix Package was offered by a company called Truk-Mate Vans Inc. (Address 820 Norway Drive E, Annandale, Minnesota). They did mostly van conversions but they also did a Suburbans conversions and even truck and minivan conversions. There is very little information about the Gran Prix Conversion Package on the Internet as the company no longer exists but what I did find indicates that Truck Mate announced the availability of the 20th anniversary edition of the Sterling Coach and Gran Prix van conversion models from TrukMate Vans Inc back in Jan 1993. This put the date back to 1973 as the beginning of their conversions. Other references I found show brochures for Gran Prix Van Conversions as late as 1999. If you have a Surburban Gran Prix or any other Gran Prix conversion, please email me!

This apparenty was the old location for Truk-Mate, probably where they produced the parts and pieces that got shipped to the local shops that installed the conversion package:

Truk-Mate no longer does van conversions and either sold or changed their name to Truck-Mate Toppers which deals mostly with Truck Canopies now and a few other truck accessories. Their web site is and they are located at 540 Elm Street, Annandale, Minnisota.

1988 GMC Suburban Gran Prix High Sierra 4x4

After 4 years of looking for Gran Prix Suburbans, this is the first 1988 I came across which leads me to believe this is the first year the Gran Prix Package existed for Suburbans. Despite the rust, this is a sharp looking package. The height of the tv in the center console is rediculous, but very cool. Flexsteel leather seats, roof lights, aftermarket carpet, all signature Gran Prix.


Ad Description: 1988 GMC High Sierra Suburban 1500 with Grand Prix Conversion, 350 V-8, Auto, PW/PL, Tilt, Cruise, AM/FM/ Cass, Air conditioning front and back (needs a charge), 4 Leather Captains seats with 3rd row bench seat, TV with old VCR still works. Has 3/4 ton back leaf springs, has some rust but runs good, would make a great hunting vehicle. This Gran Prix Suburban was found on Craigslist on July 1, 2018 in Maple Lake, MN for $2200.



1989 Chevrolet Suburban Gran Prix? Conversion 4x4

I believe this is a Gran Prix edition, the oak console in this truck looks very similar to the console in mine and the seats look to be identical. It has a moon visor, looks to be a Lund, and the grill guard looks to bee the same as the one they used on a 1990. The truck looks to be repainted and I don't see any original decals or badging. I also believe this truck had a sunroof because the mood lighting switches are mounted on the console which is where they would have been located if there was a sunroof. I contacted the seller on craigslist, waiting on a response.

1989 Chevrolet Suburban Gran Prix Conversion 4x4

Found this 89 Gran Prix Suburban on Craiglist, I had to say I was pretty excited to find it as it's the first one I found with the original paint scheme still intact. Based on the ad, it looks like the owner had tried to sell it previously but the buyer didn't show up, so it went back up for sale in March 2015 for $800!. Looks a litte rough but apparently runs like a top still looks original with the original paint of course and and interior. The owner said he would email me more photos.

1989 Chevrolet Suburban Gran Prix Conversion 4x4 with T-Top Sunroofs

This is the 1989 I purchased from Gig Harbor Washington back in November 2015. Even though this truck at 230+ Miles on it, it was mechanically kept up by the previous owner who had it for 22 years. I purchased it as a keeper and began putting work into it to get it back to original condition. This is how it looked when I purchased it.


This is how it looked just before I sold it. I had a new radiator installed, new windshield, new drivers side quarter glass, new battery, and detailing. I restored the center oak console, made new lower door panels out of oak and cleaned the carpets. The truck was sold to a great guy named Mike two provinces over in May of 2016.

1989 Chevrolet Suburban Gran Prix Conversion 4x4 with T-Top Sunroofs

This 1989 Gran Prix belongs to Daniel S. who lives in Kalispell Montana. His truck is beleived to have 42k original miles and is in excellent unrestored condition. It has the Gran Prix Package installed by LeRoys Customs and it appears they added custom paint to the center giving it a truely deluxe two tone paint job. It has had extensive mechanical work done to it and it runs like a top as well it has brand new tires. Flexsteel seats, t-top sunroofs, barn doors, tow package, rear AC and all the regular Gran Prix bells and whistles makes this truck very desireable.

1989 Chev Suburban Gran Prix Conversion

Description: None



1989 Chev Suburban Gran Prix Conversion

Description: Fourth owner, the truck is mechanically very solid, as $9000 of work was put into it since purchased in 2007. Most of the paper work from the second and third owners and all of my own records for your review. The first owner was a dealer. I would have no issue driving the thing across country tonight if I had to. If you want to spend about $800 on replacement sheet metal and have some time, you'll have a dependable work truck. I didn't get an estimate, but imagine $2000 of crude bodyshopping would get it legal, depending on your inspector. Or, just buy the thing for the drivetrain and parts...or use it on the farm. I had the tranny rebuilt about 10,000 miles ago by J&S Transmissions and is fine. The engine was replaced at about 180,000mi with a BF Goodrich crate engine. The engine runs great [350 with TBFI] and started up immediately last weekend when it was zero degrees out. It doesn't burn oil (it leaks a little though) and has good, uniform compression. The tires have about 10,000 miles on them and are nice $600 worth of rubber at this point. As you'll see from the pictures, it has four captain's chairs and interior "disco lights" from the conversion-van that was done after the factory. The first owner was a dealer in Montana, the second owner bought it from him and then their pastor used it on an Indian reservation there before moving to MN. I have the custom third-row seat, but the fabric is in awful shape as mice ate at it in storage. A person can put a (6)12ft 2x10 boards inside the truck AND close the doors. You'd have to remove the back seats (takes about 20mins with 8 bolts from underneath) to haul a 4x8 sheet in it. Found for sale on Craigslist for $1500 on Jan 23, 2018

1990 Chevrolet Suburban Gran Prix Conversion 4x4 with T-Top Sunroofs

Found on Craigslist in Rockford Washington on April 16 2017 for $1100. Truck hit a deer and caused grill damage.



1990 Chevrolet Suburban Gran Prix Conversion 4x4

The owner of this Gran Prix contacted me back in April 2015 and was looking for more information about the Gran Prix conversion and what the truck was worth. I wasn't able to be of much help other than what little information I have on this web site. The Suburban was for sale at that time, if anyone is interested, I can pass on the contact information. What's interesting is the search light mounted on the roof, I have no idea if that came that way but I think it was added later based on how it comes into the truck so close to the courtesy lights. A few other things I noticed that is different that my Gran Prix is the lack of lights in the moon visor, but the addition of the air deflector above the rear barn doors and the Gran Prix horn cap on the steering wheel. The paint is obviously original and it appears that at least a few graphic schemes were offered as this one is different than mine. The location of the Leroy's Custom Painting decal is in a different location as well.




1990 Chevrolet Suburban Gran Prix Conversion 4x4

This is the first Gran Prix that I've seen in a blue color combination with grey interior. This one has the sunroof option, Gran Prix steering wheel and rear spoiler. It's lifted with 35s, has a rebuilt rear end. It has 175,000 miles on it and it's sad to see the paint faded. This was for sale in Echo, Oregon in November of 2015 for a "reasonable offer".

1991 Chevrolet Suburban Gran Prix Edition

This was Joseph's 1991 Gran Prix Suburban. According to Joseph, the conversion included all of the typical Gran Prix options except the paint was a solid custom color. While in his posession, he had the interior re-upholstered and it looks fantastic. A custom subwoofer box and upgraded speakers were added and upgraded surface mounted LED lights on the interior roof. Here are some photos of the truck before the interior was re-done.

Here are some photos after the interior restoration:


June 14 2020 Update. Found Joseph's truck on Craigslist up for sale. Sadly it's not in the same shape and looks to have been driven pretty hard.



1991 Chevrolet Suburban Gran Prix Conversion 4x4

Found this Blue 1991 Gran Prix in Seward Nebraska with 182,314 miles. It's a little rough, but complete and original. VIN 1GNEV16KXMF131890. This is the first blue one I've seen. With the bumper guards for 1991, they had to use a different bush guard up front, limiting the number of accessory lights from 4 to 2. Also notice there are no interior light options, and sadly no interior roof mood lights, definitely without the horizonal light strips, the headliner is now sagging as so many of them do. The paint scheme is very similar to the 1989 and 1990 but they had 3 vertically slanted stripes on the door instead of 1 big one. Not sure if the bucket seats are Flexsteel, there is no emblem on the arm rests however they may have come off on the pivoting portion of the arm rest.




1991 Chevrolet Suburban Gran Prix Conversion 4x4

This 1991 Gran Prix was listed on Ebay on Oct 13, 2018. Looks like it's in pretty decent condition. It has a lot of factory options like roof rack, power mirrors, rear A/C and rear spoiler. With the Gran Prix package options were purchased like moon visor, sunroof, leather seats, and cell phone! You can still see the Leroy's Customs logo on the rear left door which indicates it's probably still all original paint as well it still has the key scratch protectors around the locks which are very hard to find by the way. 107,000 miles, 1GBEV16K8MF147454, 2nd owner, 40 gal tank, tow package, RC Fog lights, running boards, Rancho RS9000 with inboard pump, Gran Prix Customization includes mobile phone, wood panels, leather, sunroof and new Michelin tires.




1993 Chevrolet Suburban Gran Prix Edition

The owner of this Gran Prix contacted me looking for a graphic of the Grand Prix logo so that he could add them back to his Suburban as the truck was repainted after an accident. I was able to help him out by working with a photograph of the logo from my Suburban. Here is the high resolution graphic if anyone is looking in both GIF, JPF and EPS formats.
