The Build Will Appear At SEMA 2022

Flat Out Autos 2 Door Conversion Build

The team at Flat Out Autos has recently revealed a rendering of their next build: a two-door GMC SUV with a removable roof. Of course, those that look fondly at the Chevrolet K5 Blazer or GMC Jimmy will be all over this one. And to get more info, MC&T reached out to Flat Out Autos to get more information on the exciting new project.

The new build will be based on the GMC Sierra and Chevrolet Silverado platform, and according to Rob Hester from Flat Out Autos, they will also be able to offer it in HD with a Duramax engine. So at its heart, the two-door vehicle will be a truck. The new build is expected to be revealed by mid-June, and it seems that there has been a higher demand for the modern 2-door conversion than they had expected. As a result, 2022 will likely only see around 8-10 units produced, “but if the demand is still there, we will continue to increase production for 2023.” Pricing for the 2 door conversion will include the new donor 2022 Sierra or Silverado, and will come to around $120,000 USD.

Flat Out Autos is very familiar with building vehicles like this. However, new GM vehicles feature the Global B electrical architecture, creating problems for projects like this as the ECU/TCU of cars is now encrypted.

The company doesn’t modify the vehicles’ software; instead, they “have adapted the vehicles to incorporate all of the existing sensors and safety items.” Additionally, for those that want it, Flat Out Autos will be offering lifts, upgraded shocks, wheel and tire packages, and an optional supercharger for the 5.3-liter V8 engine.


While we only have renderings of what could be at the moment, the reborn GMC Jimmy from Flat Out Autos plans on debuting at the 2022 SEMA Show. Those who don’t live in the United States can get excited since Flat Out Autos does export their conversions, having sold four of their four-door K5 Tahoe conversions to the Royal Family in Abu Dhabi. According to Hester, there was also a lot of interest from the UAE before Covid.

Lastly, we asked what the current wait time for one of these vehicles would be. “The first one will take about 5 months and will serve as our prototype for fixtures and jigs to maintain consistency, once we are finished with the prototype, we are targeting being able to turn around the complete build in about 60 days.”

Zac's love for cars started at a young age, after seeing the popular Eleanor from Gone In 60 Seconds. From there, fascination and enthusiasm blossomed and to this day the Ford Mustang remains a favorite. His first job started out detailing cars, but also provided the opportunity to work on restoration including an 1968 Ford Mustang, Pontiac Firebird, and a C3 Corvette, though he left that job before further work and experience could be had. From there, he was a detailer at a car dealership before quitting that job to try and finish college.

Much of his free time while studying was spent watching YouTube videos regarding new cars, or off-roading. 4WD247 is a personal favorite channel which rekindled a dying flame in car enthusiasm, now tailored towards trucks and SUVs and the fun that can be had building up an overlanding rig, and going on adventures, though, that chapter remains unwritten for the time being.
