Dodge is expanding its commercial truck presence with the launch of the all-new, “big rig styled” 2008 Dodge
Ram 4500 and 5500 chassis cabs. They fit into the class 4 and 5 chassis cab segments — between 14,000 and 19,500 lb GVW.

Shown at the recent Chicago Auto Show, the trucks feature the largest standard fuel tank (52 gal) and largest brake rotors in its class, says Dodge. Said to have an “upfit-friendly design that reduces costs for body-builders and customers,” all chassis components are below the frame surface for easy adaptability. The trucks are offered in dual-rear-wheel models and four cab-axle lengths (60, 84, 108 and 120 in.).

The standard 6.7-liter Cummins Turbo Diesel is rated 305 hp at 3000 rpm and 610 lb ft of torque. It has B5
biodiesel compatibility and a reduction in particulates and nitrogen oxide (NOx) that comply not only with 2007
EPA heavy-duty emission standards, but 2010 as well. The engine has life-to-major overhaul intervals of 350,000 miles, Dodge says.

The 4500 and 5500 offer a six-speed automatic transmission with power takeoff or a six-speed manual, also with PTO. An electronic-shift transfer case is offered and a factory-installed exhaust brake contributes to both safety and superior brake life.
