According to edmunds for the 2009 Dodge Ram 1500. The 2009 Dodge Ram 1500 has been fully redesigned. Highlights include a new rear suspension design, updated styling, more power and up-to-date technology.
The 2009 Ram 1500 is the first full-size pickup that throws leaf springs into the time capsule. Instead, it has a heavy-duty coil rear suspension that not only results in a remarkably civilized ride, but also saves weight, enables the fitment of a rear antiroll bar and improves off-road performance. Don't expect buttery smoothness -- the springs still need to be sturdy enough to sustain the Ram's massive hauling and towing capabilities, so some jiggling over bumps and freeway hop is inevitable. But for a full-size truck, the Ram's relaxed ride is revolutionary.
The 2009 Dodge Ram 1500 is a full-size pickup available in multiple body styles and bed lengths. The regular cab seats a maximum of three people on its standard bench seat, and it can be had with either a 6-foot-4-inch bed or an 8-foot version. The extended cab ("Quad Cab") can seat up to six in two bench rows and comes only with the 6-foot-4 bed. The Ram's crew cab model expands rear-seat legroom even further, but is only available with a 5-foot-7-inch bed.
Even without the upper-crust Laramie's leather upholstery and wood-grain trim, the 2009 Dodge Ram 1500 offers one of the nicest cabins in its segment. Controls are well placed and within reasonable reach. The overall design is attractive, with multiple colors and textures (unlike the GM trucks), but not overstyled like the Tundra. Materials quality is among the best found in this class, with nicely textured low-sheen plastics that look durable.
With its body-on-frame construction, the 2009 Dodge Ram exhibits the expected body jiggle over bumps. However, its rear coil-spring suspension virtually eliminates the harsh ride previously endemic to full-size trucks. The result is a much smoother, more sophisticated ride that sets the Ram apart from all other traditional pickups.
