The fourth generation of Dodge Ram was introduced for the 2009 model year. Starting in 2010, Dodge separated the Ram into its own brand, but the model continued to be a range of light, medium, and heavy duty pickup trucks. Regular, quad, and crew cabs were offered, as well as chassis cab variants, which were available in rear or four wheel drive. A range of powerful inline six, V6, and V8 engines were offered on the fourth generation Ram, which was built until 2018, when the Fifth Generation Ram was introduced.
