2013 Dodge Ram

High Output 6.7L CUmmins Turbodiesel






Since Ford introduced the 6.7L Power Stroke and GM released its 397 hp Duramax, a cash strapped Chrysler has struggled to compete with its Cummins powered Ram. Even when Ram Trucks attempted to catch up, it seems they were always 2 steps behind their competitors. So how does a battered, beaten, and torn company stir up the marketplace? By completely redesigning the Ram HD for 2013, sparing no expense and leaving no stone unturned. How does a high output version of the 6.7L Cummins, backed by a stronger Aisin HD transmission, sitting between a redesigned chassis sound? It's safe to say that Ram Trucks is laying down a royal flush for 2013; the Ram 2500 and 3500 models will be offered in four different engine/transmission options. The 5.7L Hemi gas engine is still available, and the 3 diesel options are as follows:

6.7L Cummins w/ G56 6 speed Manual Transmission

• 350 hp @ 2,800 rpm.
• 660 lb-ft @ 1,500 rpm.
If you want the new Ram HD with a handshaker, we understand the allure of shifting your own gears. However, you'll give up between 140 and 190 lb-ft of twist since the manual trans doesn't have the input torque capacity that the mighty Cummins demands. The good news is that the G56 equipped trucks gained 60 lb-ft over previous years.

6.7L Cummins w/ 68RFE 6 speed Automatic Transmission

• 370 hp @ 2,800 rpm.
• 800 lb-ft @ 1,600 rpm.
Tweaks to the standard 6.7L Cummins gives you another 20 horsepower to play with, and the torque curve has reportedly been fattened.

6.7L High Output Cummins

• Backed by the Aisin AS69RC 6 speed automatic transmission (based on the AS68RC only offered in Ram chassis cab 4500 & 5500 models).

• 385 hp @ 2,800 rpm.

• 850 lb-ft @ 1,600 rpm.
• Unique dual inlet active air intake system that switches between inlets to ensure the coolest air is drawn.
The high ouput 6.7L Cummins is sure to shake up the market, with 50 lb-ft more than the nearest competitor, a broad/flat torque curve, and improved fuel economy.


In addition to these three engine options, Ram has upgraded the following components to ensure longevity, reliability, fuel economy, and tow/payload capacity.
• Upgraded high efficiency mechanical fan & dual radiators keep the Cummins cool under extreme loads and operating conditions.
• Dual transmission coolers ensure the life of your automatic transmission.
• Improved efficiency intercooler (charge-air-cooler or CAC) with reported 25% better heat dissipation.
• New and improved exhaust brake.
• Larger EGR cooler and the introduction of the SCR system, which requires the use of urea/DEF and yields 10% better fuel economy.
• New, stronger frame material. Frame is fully boxed in the rear, wider in certain sections to reduce roll, and contains 8 cross members.
• Front axle disconnect system for improved fuel economy, massive 11.8" rear axle.
• Upgraded receiver system allows up to 1,800 lbs. tongue weight and 17,000 lbs. conventional towing.
