This engine actually has some notable differences including:Ī small compression increase and other updates allow the high output version to offer more power and torque. Other Major Ram 5.9L Diesel ChangesĢ001 saw the introduction of the high output 5.9 Cummins only available with the NV5600 6MT. *12v 5.9 Cummins are also known as the 6BT while 24v diesel engines are the ISB 5.9. By 2007, the 5.9 Cummins offers an impressive 325 horsepower and 610 lb-ft.Ī large part of the power improvements were due to the 4-valve per cylinder design and electronic engine management. Even with its initial introduction power went up by 20hp and 20 lb-ft. As the name suggests the 5.9 Cummins is a 24-valve engine instead of 12 valves. Here, we’ll simply lay out some of the basics.Ģ4v Cummins engines came out in the middle of 1998 – hence the 1998.5 designation. Check out the previously linked article for more info. The 12-valve versus 24-valve Cummins is a big topic when it comes to the Dodge Ram 5.9L diesel engine.

You’ll notice with the 6.7 Cummins the automatics are actually capable of a lot more torque than the manual options. However, times have changed a lot since then. That’s the primary reason manual 5.9 Cummins deliver more torque. In the past, automatics were a major limitation to torque.

Higher torque is simply due to software changes for the manual versions. These are all the same engines for each specific model year. That’s especially true for the 24v Cummins where the manual is 40-140 lb-ft of torque higher. High output engine introduced (only for NV5600 manual trans)Ĥ60 lb-ft 1,400 (auto) 555 lb-ft 1,400 (man)Ĥ60 lb-ft 1,400 (auto) 600 lb-ft 1,600 (man)Īs you’ll notice the manual transmission 5.9 Cummins diesel engines offer quite a bit more torque than the automatic. Below each horsepower and torque timeline we will discuss a few of the primary updates that allow for power and/or torque increases by model year. It’s still in production to date with up to a whopping 1,000 lb-ft.Īnyways, we’ll keep it there for now. In 2007.5, the 6.7 diesel replaced the 5.9 engine. There are two primary variants known as the 12v and 24v Cummins engines. The 5.9 Cummins was available from 1989 to 2007. We will split this up into two sections – one for the 5.9L Cummins and the other for the 6.7L Cummins turbodiesel. In this guide, we discuss Ram 5.9 & 6.7 Cummins horsepower and torque by model year along with some updates that support the increases. Horsepower and torque can vary wildly by Cummins model year trucks.

Despite only two primary engine designs for a 30 year span there are many differences. These two engines have powered Dodge Ram trucks since 1989. The 5.9 and 6.7 Cummins diesel engines are common options in Dodge and Ram trucks.
