In 2019, RAM 3500, 4500 and 5500 Chassis Cab models equipped with a Aisin automatic, see an increase in horsepower and torque to 360 hp and 800 lb-ft.

In addition to moving to a higher capability high pressure pump, several critical features were included to maintain the proven reliability and durability our customers have come to expect:

  • A Compacted Graphite Iron (CGI) material for the block allows us to increase the cylinder pressure capability while reducing the overall weight by almost 60 lbs
  • A new cast-iron cylinder head containing high-temperature capable exhaust valves actuated by all-new hydraulic lash adjusters in the block eliminates the need for valve train adjustment service intervals
  • The heart of the engine is a higher-strength alloy crankshaft with a 10-bolt crank flange driving newly-designed forged connecting rods and new bearings which transfer power from the low-friction ring-wrapped pistons
  • A new larger Cummins Holset variable-geometry turbocharger optimized with heavy duty bearings, and a new compressor-side housing is a key ingredient in the new ratings, pumping 33 pounds per square inch (psi) of fresh air into the engine
  • The new fuel-delivery system includes a new 29,000 psi (2,000 bar) fuel pump and fuel rail with Cummins Filtration “filter in filter” NanoNet® technology

2019's Hydraulic Lash Adjusters completely eliminate the need to adjust the overhead. The interval for the Fleetguard breather filter has been extended to 75,000 miles.

Maintenance intervals for fuel filter replacement remains at 15,000 miles (24,000 km). Oil change interval stays at 15,000 miles (24,000 km) and is duty cycle based. This engine uses an oil change monitoring system which will display a message on the vehicle information center that alerts the driver to change the oil.

Your new Cummins 6.7L Turbo Diesel engine requires low-ash engine oil; failure to use this type of oil can result in serious damage to the exhaust aftertreatment system in your vehicle. Be sure to purchase engine oil that meets CES 20081 standards.

Due to EPA regulations, owners of MY07 and later Cummins 6.7L turbo diesel-powered highway vehicles must refuel only with Ultra-Low Sulfur Diesel (ULSD) fuel meeting a 15-ppm on-highway requirement. Use of all other fuels is prohibited and may result in damage to the engine and/or the aftertreatment system. Be sure to purchase your diesel fuel from a reputable fuel station. For most year-round service, a high-quality No. 2 diesel fuel that meets ASTM specification D-975 (0.0015% sulfur level) will maintain good performance. EPA requires retail fuel stations that carry and dispense LSD and ULSD to label the pumps with a Low-Sulfur Highway Diesel Fuel and an Ultra-Low Sulfur Diesel label.

In addition, diesel fuel sold for off-highway use should not be used in any Cummins turbo diesel engine. This is due to off-highway fuels not necessarily meeting the fuel cleanliness or lubricity requirements for on-highway fuel specifications. Use of such off-highway fuels can result in accelerated wear to fuel system components.
