Is It Worth It To Buy a Dually Truck?

June 30, 2022

Everything You Need To Know About Dual Rear Wheel (DRW) Trucks

If you guys know us, you know that we like 'em thick - talking about trucks here specifically. We're talking 12-wides, 14-wides, 16-wides, you get the picture. But there's one thicc type of truck that we especially love: duallys.

Dual Rear Wheel (DRW) pickups, otherwise known as duallys or fat bottomed girls, have become super popular recently, but if you want one you should know what they're like, how they tick, and what's involved with owning or modding one. So, let's jump right in and see what's up with these trucks.

How Did Duallys Become Popular In America?

When we look at the dually pickup, it's important to note that we're talking about the passenger market. DRW configurations have been around forever - basically since the first pickups were built in 1897 - but the issue was that up until the 70s, the only way you could get one was in a commercial vehicle. These trucks would come with dual rear wheel tires from the factory, and either came with a flatbed or without a bed at all - that meant that if you wanted a pickup bed, you had to source the parts yourself and pray to God you had everything hooked up right.

That all changed in 1973, however - this was the year that GM's big boy truck brands (Chevy and GMC) would be ending their current second-generation pickup truck reduction. They'd instead be replacing that with the square body trucks that have become so iconic in the public eye - everyone either had one, still has one, or wants one. Not only was this exciting from a new truck standpoint, but with this shift, GM would forever change the truck market as we know it.

What Was The First Dually Truck?

Along with the new redesign of its truck lineup, General Motors announced the first-ever dual-rear-wheel pickup truck available from the factory. That was the GMC C30, a super sweet ride that featured two rows of seating, four doors, and four tires on the rear axle. Under the hood, it packed a slightly less impressive punch with GM's still-iconic 350cc engine, which made 155 horsepower and 225 pound-feet of torque.

Although the C30 didn't set any land speed records or make thousands of pound-feet of torque, the big dually (as it was branded) would set the stage for the working truck of today. Ford and Dodge would also follow suit, developing DRW trucks of their own, and by the 90s each member of the Big Three had diesel-powered dually options.

Performance and Design Capabilities of Dually Pickups

A lot has changed since the 90s and especially the 70s, and pickup trucks have just continued to get better. What sets dually trucks apart is how they're built - when you look at the differences between them and, say, a three-quarter-ton truck, the main difference is that a dually will be quite a bit heavier even though it might have the same frame as a single-rear-wheel model. They'll usually have the same engine and transmission, but that's where the similarities end.

Duallys often come with heavier axles, heavier suspension setups, and just more meat on the bones than SRW options. That's important because with the added rear tires, dually trucks are rated for quite a bit more in terms of payload and towing capacity.

Take the all-new fifth-gen Cummins, for example - we talk about these trucks all the time, but that's because they're badass as hell. When properly optioned, these new trucks have a tow rating of 40,000 pounds; for reference, that's as much as 2.5 T-Rexes or five full-sized hippos.

What Wheels Fit Best On A Dually Truck?

Now, if you're looking for wheels or tires for your dually, fitment can be a bit difficult for a couple of reasons. First of all, most dually trucks come with an 8x200mm bolt pattern, which is different than the 8x170 or 8x180 patterns that are most common on diesel trucks. On top of that, when you're shopping for dual wheels, you're really shopping for three sets of two wheels. Up front, you're either gonna have a super deep dished-in wheel to keep the turning radius sharp, or you might have a single 12 or 14-wide. But in the back, that's where things get fun.

Because there are two different wheels on each side of your DRW truck, the offset has to be different - otherwise, they wouldn't line up. For this reason, your inners will have to have a super high offset just so they can suck in. Your outers, meanwhile, will be a super low offset so they can be dished out. This is made even more confusing because depending on the size of tire you want to run, you'll need a different offset wheel or a spacer of some sort so your tires won't rub when they're inflated.

Should You Buy A Dually?

Above all that, the question remains - why would you want a dually truck in 2022? The choice is yours, but what it comes down to is whether or not you need one. If, say, you need to be towing a lot of stuff around, dually trucks are kings in the business. They handle the large weight and big trailers easily, and they look incredible.

For other truck buyers, it might be about having a good-looking, functional work truck that can get the job done and break a few necks on Friday night. For this, dually trucks can be perfect too if you know what you're looking for.
