On the exhaust of the Cummins 6.7-liter Turbo Diesel option in Ram heavy-duty pickups, a diesel particulate filter and an adsorber catalyst to reduce oxides of nitrogen (NOx) satisfy EPA’s 2010 on-road diesel emissions limits.

Dodge's redesigned 2009 Ram 1500 pickup trucks have five trim levels that go from base to posh. If you run a fleet, you're likely to choose the basic-trimmed ST, and that's what I drove during a show-and-tell event near Santa Barbara, Calif., late last summer.
Chrysler barged into the medium-duty class with the 2008 Dodge Ram 4500 and 5500 Chassis Cabs. They are aggressively specced with gross vehicle weight ratings of 16,500 and 19,500 pounds, respectively, and standard 6.7-liter Cummins turbo diesel engines. There's a choice of six-speed automatic or manual transmissions.
