6.7L Cummins 800 lb-ft of Torque


February 2011:


Dodge announced earlier this month new torque ratings for the 6.7L Cummins turbodiesel, previously rated at 650 lb-ft, now producing 800 lb-ft @ 1,600 rpm. Horsepower output remains the same 350 hp @ 3,000 rpm. The extra 150 lb-ft of torque is a result of an upgraded PCM (power control module). Peak horsepower output remains unchanged, but an estimated 23% more horsepower is available throughout the working rpm range. The new high output 6.7L Cummins is standard on all 68RFE automatic transmission equipped Ram 2500/3500 trucks. To support the extra twist, the 68RFE 6 speed auto trans receives an upgraded torque converter and new shift schedule. An engine mounted water-to-oil trans cooler and new crankshaft damper have also been introduced to support the upgraded torque rating. The latest upgrades boost the Ram's towing capabilities, allowing it to tow a maximum 22,700 lbs 5th wheel and 12,000 lbs conventional. Additionally, the gross combined weight rating is now a maximum 30,000 lbs, increased from a previous 24,500 lbs. Despite the increased performance, the 6.7L Cummins does not require the use of diesel exhaust fluid (DEF) and Dodge maintains the standard 5 year/100,000 mile warranty. The Ram has officially stepped back into the game, surpassing GM's Duramax in torque and matching Ford's Power Stroke, though the 6.7L Power Stroke and 6.6L Duramax still have the Cummins beat in horsepower.


Both the current Duramax and Power Stroke require the use of diesel exhaust fluid. While it may be an inconvenience to keep the DEF tank filled, use of selective catalytic reduction allows the Duramax and Power Stroke to achieve better fuel economy than the non DEF 6.7L Cummins.


Dodge will not be offering an upgrade for current 6.7L Cummins owners like Ford did for 6.7L Power Stroke owners in August 2010.
