A pick-up truck that has dual rear tires on each side is called a dually truck. These dual tires, making a total of four rear tires, allow dually trucks to lift and haul more weight than the average pickup truck. A dually truck will typically weigh more than a ton, and can carry more than 2,200 lbs or 1,000 kg on their floor beds, and haul larger trailers. This is because these trucks are used for the kind of haulage where your average truck will prove deficient. When you want to haul a racecar or your fifth-wheel coachman, you need a dually truck.
Features and Advantages of a Dually Truck
Fitting two extra rear tires on a pickup does not a dually make – indeed, there is more to the truck than just the extra tires. For one, the rear tires installed on these trucks are larger than your normal pickup tires. Dual tires are usually 16” in size, however these days 18” tires are also becoming popular.
Another major modification with these models is their stronger suspension – because they are designed to carry and haul more weight, their rear suspension is much stronger than that of an average pickup. However, this is not true for some models, such as the Ford F-350, which is a dually that uses the same suspension that is installed in the F-250.
These features make a dually truck the best choice for construction and mining companies that need the maximum hauling power that they can get. Private individuals or other companies that require more powerful trucks are also served well by dually trucks. Their extra tires ensure more traction with the surface of the road, which allows for better braking and handling, especially when hauling larger trailers and equipment. The wider wheelbase also adds more stability to the vehicle.
Top Dually Truck Models
The following are the dually truck models launched by the top US manufacturers. All of them are available with diesel and gasoline engines.
Chevrolet Silverado 3500 The Chevrolet Silverado is the latest line of full-size pickup trucks manufactured by General Motors. The Silverado 3500 is the Heavy Duty version of this series, and is available with dually tires and stronger suspension, apart from other appropriate modifications. This model is available with two engines, the Duramax V8 engine with 300 hp (224 kW) at 3000 rpm, and the Vortec 8100 V8 engine with 340 hp (254 kW) at 4200 rpm. The Chevrolet Silverado 3500 can haul 5,511 pounds (2,500 kg) and tow 16,700 pounds (7,600 kg), making it one of the more powerful dually trucks in the market. This model is also known as the GMC Sierra.
Dodge Ram 3500 Heavy Duty Dodge Ram from Chrysler is one of the most popular series of full-size pickup trucks in the United States. The Dodge Ram 3500 is the heavy duty and dually version of this series. The Dodge Ram 3500 Heavy Duty was first launched in 2009 after its unveiling at the Chicago Auto Show. It comes with 2 axles that have three axle ratios, and 17-inch wheels. This model meets emissions standards for all 50 states, and does not require the use of Diesel Exhaust Fluid (DEF). The model comes with a Max Tow package which allows for 22,750-pound maximum towing capacity – so if you want some real hauling to do, the Dodge Ram 3500 is the dually truck for you.
Ford Super Duty F-350 The F-350 is a dually which is available in different body configurations including as regular cab, extended cab and crew cab. It has a number of powertrain options and trim levels to choose from too. The cabin has recently been redesigned with higher quality materials. You have the choice of two engines, both available with six-speed automatic transmission. You can either go with a 6.2-liter gasoline engine with 385 horsepower and 405 pound-feet of torque or with a 6.7-liter PowerStroke turbodiesel that cranks out 400 hp and 800 lb-ft of torque. This truck has been designed to give quiet service, so if you want a relatively quiet but powerful dually truck, the Ford Super Duty F-350 is the choice for you.
Dually Truck Precautions
With dually trucks, you have to make sure that the rear tires are not in contact with each other at any time; such a contact can prove dangerous while driving. With these trucks, you also need to rotate the rear tires regularly. Indeed, the warranty for these tires is applicable only when you regularly rotate the tires. Rotating the tires is more important on a dually when compared to a regular pickup because of the different positions in which tires are installed on the rear axle. You should also make sure that the rear tires of your truck are inflated to the right degree – given the weight that they will be supporting, it is important that they are inflated properly.Due to their wider wheelbase and the two extra tires, and stronger frames, dually trucks are the last resort when you want a powerful pickup to haul larger trailers and other equipment. Dually trucks have more stability than their single-rear wheel cousins, which also makes them safer, especially in winters and other harsher conditions. All these extra features make a dually truck costlier than their normal cousin, but that is a cost that definitely pays for itself over time.
