What is a Dually Truck?
A dual rear-wheel truck (DRW) – often referred to as a dually – is a heavy-duty pickup truck with two rear wheels on each side, allowing more road contact and width for greater stability, balance, and traction while driving. Chances are you have been behind one of these widebody vehicles on the road and noticed its brawny stance and muscular fenders.
With four back wheels instead of two, and a stronger rear axle, a dually truck can handle a larger amount of payload weight and offer more towing capacity compared to its standard single rear-wheel (SRW) pickup truck counterparts. For example, a 2020 Chevrolet Silverado 3500HD V-8 turbo-diesel (DRW) truck can haul 2,215 more pounds and tow 5,500 more pounds than its SRW version. Add a gooseneck hitch to both trucks and the dually out-tows the standard version by a remarkable 14,000 pounds.
Most dually trucks are also equipped with bigger, stronger brakes for additional stopping power, as well as heavy-duty shocks and springs for greater capability to tread uneven terrain and rough driving surfaces.
