Top 10 Diesel Dually Trucks

Dynamic duallies.

Aug 6, 2020
As pickup trucks go, duallies are the top-tier, upper-echelon, six-wheeled leaders of the pack. And while they can be powered by gasoline engines, the enthusiast rank and file knows that duallys with diesel powerplants are really what's happening in the truck scene.
We've certainly covered more than a fair share of duallies over the years, from work rigs to full-on custom masterpieces, and we're always looking for trucks and information to add to the collection. Here are some of the dualie highlights we've published. It's truly impossible to not like these trucks.

1985 Dodge Ram D-350

Humberto Ortiz bought a diesel-swapped, stick-shift, crew-cab 1985 Dodge, and through his company (Vulcan Specialties in Lubbock, Texas), jettisoned it into the next stratosphere of custom. While it's well known that 5.9L Cummins oil burners weren't formally mated with Dodge trucks until 1989, crew-cab D-350 pickups were actually dropped from production in 1985. Technically, Humberto has a first-gen truck that the factory should have built but never did. That's what makes it cool.

2018 GMC Sierra 3500HD Denali

Through determination and refusing to let anything stop him, Jonathan Barber commissioned Street Dreamz (Beckley, West Virginia) and ATC Conversions in Markle, Indiana, to build this super-trick 2018 GMC Sierra 3500HD Denali. A coal-mining accident left Jonathan paralyzed and forced to use a wheelchair. But thanks to the technology and innovation that's highlighted in this feature, he drives and enjoys his truck on a regular basis.

2007 Dodge Ram 3500

Our rundown isn't all about the lookers. Chris Patterson's dualie is a badass. The Official Alternate at 2019 Diesel Power Challenge Presented by XDP, this rig unfortunately did not compete in the event. However, since coming to DPC, Chris added a third turbo and made other significant changes to the 5.6L Cummins engine, raising the horsepower from 1,140 to 1,343 (at the 2020 ATS Diesel Performance Gauntlet Challenge) and pushing the big six-wheeler into the 9-second zone on the quarter mile.

2007 Ford F-350 Super Duty

A snake in its own right, Jason Hulst's Striker dually features graphics and accessories that pay homage to Carroll Shelby's legendary AC Cobra. And, like the 427ci gas engine that powered its two-door inspiration, the big rig's 6.0L Ford Power Stroke diesel is hopped up with bits that add more than 130 hp and 231 lb-ft of torque.

2016 Ram 3500

While Sebastian Luna's manually shifted (G56 six-speed) dually came about as a result of him "having it up to here" with the frustration of breaking automatic transmissions (four times) in other trucks, he didn't go hog wild with the Mega Cab until an aggressive ECM calibration wreaked havoc on its 6.7L Cummins engine. Tyler and his team at Truckwurx in Louisiana revamped the drivetrain, and with help from friends at Kaotik and Spike, constructed the blue brilliance that earned Sebastian the privilege of displaying the rig at the SEMA Show.

2006 Ford F-550 Super Duty "Fummins"

When a 6.0L Power Stroke engine, six wheels, and four-wheel drive proved to be insufficient, Rick Newland opted to replace the Ford diesel with a compound-turbocharged 5.9L Cummins engine. With an NV5600 six-speed manual transmission behind it, the drivetrain is exactly what Rick needs for towing big-time weight anywhere it needs to go.

2006 Dodge Ram, Ford, and Chevrolet Shootout
Crew cabs, diesels, and dualies all. Back in the day, this facia-to-tailgate six-wheeler shootout was one for the ages.

What Is a Dually?

Are you looking for clarity amid these reports on awesome trucks? Here's our take on what a dually actually is. (Note: Since this story was published, we have changed our ways and accepted "dually" versus "dualie" as the correct way to spell the word.)

1940s Rat Rod

Founded on a 1940s-vintage Mack Bulldog cab, Jose Lugo's rat rod is an amalgamation of parts from Chevrolet, Dodge Ram and Ford. While the old-school dually is cool by every standard, its compound-turbocharged 5.9L Cummins engine is the highlight.

2019 Nissan Titan XD

Wait what?! Here is another good example of a dually that should have been but, sadly, never was. With the exception of this one. Nissan debuted this one-off rig at the 2019 SEMA Show in Las Vegas. In our opinion, this one had what it takes to be a player in the one-ton space. However, had the real deal actually been produced, it probably would not have the 5.0L Cummins powerplant we were just starting to become one with, as Nissan dropped the engine from Titan the following year.
