Our Doomsday Diesel project was born from the idea that owning a diesel makes you more prepared for all the worst-case scenarios life can throw at you. We’ve been building this diesel-engine-swap project as a showcase for bulletproof technologies, and as a way to learn about (and share) ways to make diesel vehicles more reliable—not just more powerful.

Doomsday Diesel began life as a ’91 GMC Suburban 2500 4x4 with a gasoline engine backed by GM’s 4L80E four-speed automatic transmission. During the last year, we stripped the truck down to the frame and have been building it back up with a 5.9L Cummins, AAM 1150 rear axle, Dana 60-based frontend, and the whole truck rolls on a set of 37-inch-tall tires that would be at home on a military Humvee.

When choosing the parts for our build, we wanted pieces that were off-the-shelf common. That ideology helps keep the costs down, means there’s lots of options, and if society ends—we’ll be able to get spare parts. One of the unexpected bonuses of the vehicle we’ve chosen (’73 to ’91 Suburban) is that LMC Truck in Lenexa, Kansas, sells nearly enough parts to build this vehicle from scratch!
