Targeted at small-business tradesmen, fleet customers, and traditional chassis cab users, the Dodge Ram 4500 and 5500 Chassis Cabs extend the Chrysler Group’s current commercial foundation and the line-up of full-size vans, minivans, and body-on-frame commercial vehicles.

Ready to Compete

The Ram 4500 and 5500 Chassis Cabs will compete in medium-duty truck Class 4 and 5 segments with a GVWR of 14,000-19,500 lbs. Overall industry forecasts for this range of chassis cab vehicles were 140,000 units in 2006 with growth expectations to 156,000 units by 2012.

“We built the all-new 2008 Dodge Ram 4500 and 5500 Chassis Cabs for heavy-duty chassis cab buyers who want a powerful, capable, and versatile commercial-quality vehicle,” said George Murphy, senior vice president, global brand marketing, Chrysler Group. “With commercial performance, durability, and capability, the 2008 Dodge Ram 4500 and 5500 Chassis Cabs offer dominant powertrain packages, a commercial-grade upfit-friendly chassis, and bold, ‘bigrig’ Ram styling.”

Powerful & Durable

The 6.7L engine generates 305 horsepower at 3,000 rpm and 610 lb.- ft. of torque at 1,600 rpm. It’s also a clean engine with B-5 biodiesel compatibility and a reduction in particulates and nitrogen oxide (NOx) that complies with the 50-state 2007 heavy-duty emission standards. The engine also has life-to-major overhaul intervals of 350,000 miles.

The 4500 and 5500 Dodge Ram features a six-speed automatic or manual transmission with power take-off (PTO) capability. An available electronic-shift transfer case is offered and a factory-installed exhaust brake contributes to both safety and longer brake life.

The Dodge Ram 4500 and 550 Chassis Cabs models are “job-rated,” meaning they are designed, engineered, tested, and built to meet the rigid standards of commercial truck buyers.

According to Dodge, two- and four-wheel-drive models feature a recirculating ball system that provides precise response and on-center steering feel through lower internal friction. Improved power steering lines contribute to the delivery of precise feel and response for better handling.

Upfit-Friendly

Meeting all cab-axle and industry upfitter specifications, the 4500 and 5500 Chassis Cabs bring versatility and upfit-readiness with an enhanced commercial-grade, user-friendly chassis to the Class 4 and 5 chassis segments.

Built on industry-standard 34-inch spacing and flat, clean frame rails on a one-piece C-channel rear-frame rail, upfit-friendliness was a primary theme in design, according to Dodge. All chassis components are below the frame surface for easy adaptability and versatility in virtually any upfit application.

Electrical connections are userfriendly due to three-fused battery feeds routed into the cab and onto the rear of the chassis. Upfitter wire circuits and electrical schematics are identified in the body builder guide.
