What is a Dually Truck?
Dual trucks are built with two sets of drive wheels. Generally, dually are referred to as “duals.” The rear set of wheels on most dually is smaller than the front set. Each axle has its own differential and individual suspension components that allow the tires to rotate independently of one another.
In a conventional single-truck setup, each tire needs to follow the same path while turning at a corner or while going down a flat road.
How Are Duallys Built?
The strongest part of a dually truck is its connection point between the cab and the bed. This area requires an extremely strong connection if it has to support the weight of a fully-loaded truck while making a turn or going up and down an unpaved road. The connection between the cab and the bed is where dually get their strength. A lot of attention is given to reinforcing and strengthening this area so that it can properly handle heavy loads and still maintain great maneuverability.
Why Are Dually Trucks Being Built?
Dual trucks are built for commercial use. They’re typically long-haul semis that haul very heavy loads over long distances, often across the country or internationally. Some people also build dually into four-wheel-drive vehicles for recreational purposes, such as going off-road or pulling a camper.

The Dually Truck has two sets of tires in the rear.
A dually truck is a type of cab over engine (COE) truck with dual rear wheels on each side of its rear axle, distinguishing it from conventional trucks with their single set of rear wheels. Many also have dual front wheels. Other types of trucks having two or more axles (more than the conventional rear-wheel drive truck) are articulated trucks with three or more axles, and quad-axle trucks featuring four rear wheels on two axles.
Dually are often used to carry heavy construction equipment such as cranes of 60 tons + weight, oil field drilling rigs, fuel tankers, or large military equipment.
They are distinguished from a tandem axle in that the rear set of wheels is situated beneath an elevated cargo box or bed distinct from the cab, rather than being attached to a separate rigid axle suspended below the load bed by leaf springs. In addition, many have dual rear tires on each side of their rear cargo box, not just at the rear. Most have tandem rear axles or two axles on the rear of the truck. In some cases, heavy haulers may have three axles, with a fourth axle being an option rather than standard equipment.
These types of trucks are often called multi-axle trucks in Australia and New Zealand – they use this term for all types of trucks with three or more axles on their drive train, not just those as dually as described here.
In some countries, a passenger car with a trailer attached might be described as a dually. In Australia and New Zealand, this term is reserved for heavy-duty trucks only. These are the fastest-growing type of trucks in the Australian road transport industry.
