  Second generation (HB; 2003)
  The second-generation Durango was first shown as a concept dubbed Dodge Durango R/T concept at the 2003 Detroit Auto Show. It debuted shortly before the companion Dakota. Like the Dakota, it has much in common with the large Dodge Ram pickup, including a fully boxed frame. It is  longer,  wider, and  taller than the previous model. It also offered a third-row bench with three seats, giving it an eight-seat capacity. The design took its styling primarily from the Dodge Powerbox concept, which was itself based on the 1999 Dodge Power Wagon concept, and the 2003-2004 Durango R/T concept. The steering wheel and gauges are shared with the Dakota (2005-2011), and the steering wheel was only shared the Ram Pickup (2004-2008).
  Debuting for 2004 was a new coil-spring rear suspension for the solid rear axle. A Watt's linkage system is fitted to the rear axle, centering the axle and reducing rear-end skate over rough surfaces, and allowing a lower and wider cargo floor.
