2014 Ram Commercial Chassis Cab 3500/4500/5500: First Look

Along with all the big news about the 2014 Ram 1500 EcoDiesel and new engine and suspension options for the 2014 Ram heavy-duties, there's also a number of interesting changes for the 2014 Ram Commercial Chassis Cab lineup.

The biggest change for the Ram's chassis cab offerings center on the all-new 6.4-liter Hemi V-8, which is available in the 4500 and 5500 models. That means the lineup will offer buyers two different horsepower and torque ratings with the 6.7-liter Cummins engine as well as a gasoline option engine with two different horsepower ratings based on the specific gross vehicle weight rating of the truck (at less than 10,000 pounds, it's 410; more than 10,000 pounds is 367). The new gas engine will also include the same cylinder-deactivation technology found in other Rams to help save fuel costs for commercial drivers.

Additionally, the chassis cabs get the new 50,000-pounds-per-square-inch steel frames, so all have improved gross combined weight ratings to allow for much bigger payloads and trailer towing. However, don't expect to see the airbag suspension options on the chassis cabs just yet. They'll stay exclusively on the Ram HDs (2500/3500) for now. The only suspension change for these work trucks will occur on the 3500 chassis cab, which will get the same three-link change to the front end that the 2013 Ram 3500 HD got last year.

Finally, all chassis cab Cummins models will now have the same selective catalytic reduction exhaust system that includes a separate diesel exhaust fluid tank, which became available on the Ram 2500/3500 HDs last year. This is a change from the earlier chassis cab models that ran the down-rated Cummins, but it will save Ram and customers purchase costs and offer better overall fuel economy. One final improvement is that the commercial lineup will get the same interior upgrades and refinements that the Ram HD models did last year. This will be a welcome improvement for anyone who spends their work days in these trucks all day.
