Ram Chassis Cabs go higher-capacity

by David Zatz on

The 2012 Ram 4500 and 5500 medium-duty (Class 4 and 5) Chassis Cabs will be available with an optional 30,000-lb. gross combined weight rating (GCWR), an increase from 26,000 lbs, designed to help customers in agriculture and construction.

The upgrade is part of an optional “Max Tow” package, and is available on both regular and crew cab models and in 4×2 and 4×4. Changed parts include a new transfer case gear set and chain and sprocket upgrades, recalibrated transmission software and an enhanced collection of thermal management devices.

Ram 4500 and 5500 Chassis Cab trucks come equipped with the proven, commercial-grade 305 horsepower (228 kW) @ 2,900 rpm and 610 lb.-ft. (827 N•m) @ 1,600 rpm 6.7-liter Cummins Turbo Diesel engine.

Max Tow is available on Ram Chassis Cab trucks equipped with the optional, commercial-grade Aisin six-speed automatic transmission and 4.88 rear-axle ratio. A 4.44 axle is standard on 4500 models and not available with the Max Tow package. A six-speed manual transmission is standard on Ram 4500 and 5500 Chassis Cab models.

Ram 3500 Chassis Cab trucks will add a new six-speed automatic transmission in 2012 that will increase GCWR to 20,000 lbs. – a 3,000-lb. increase — and increase fuel economy. With a standard 383 horsepower, 400 lb.-ft. of torque gas engine, the Ram 3500 Chassis Cab delivers best-in-class horsepower and torque. The Cummins Turbo Diesel is available an option on Ram 3500 Chassis Cab trucks.

Ram Chassis Cab trucks are specifically designed for towing, with features such as the strongest exhaust brake in the industry – 49 percent stronger than the nearest competitor — and the largest brake rotors and pads in their class. Ram has also upgraded the trailer brake controller on Chassis Cab trucks to include electric over hydraulic capability, to further enhance its towing ability.

Ram Chassis Cab trucks offer class-leading performance in brake pad wear and brake fade resistance, with a claimed best-in-class fuel economy. In a recent comparison, the Ram 5500 Chassis Cab was 10 percent more fuel efficient than its direct competitor, which can add up to thousands of dollars a year in owner savings.

Among Ram’s best-in-class features:

• Standard Gross Vehicle Weight Rating (GVWR) of 19,500 lbs.
• Brakes last twice as long as the competition under severe use
• Better turning radius – by 10 feet – than competitors
• Largest standard fuel tank – 52 gallons
• Lowest cost of ownership in the segment, based on significant owner expenses, including fuel economy, brake wear and tire wear
