At hp and lp-ft of torque, it has enough strength for almost any job that you can throw at it, while maintaining the reliability that the best Cummins engines are known for. The turbo unit on the Cummins 5. However, the fixed unit is much more reliable and has fewer moving parts, which is exactly what the best Cummins engine should be focused on. This, combined with a lower pressure injector means that you will be less likely to blow a head gasket with heavy use.
If you are looking for an engine that will be as reliable and durable as it can possibly be, this could be a fantastic option. Sources: USEngineProduction. Figure 6: The 5. The Cummins 5. It utilizes a compacted graphite iron block for a durable construction that is still light enough for smaller applications.
If you want an engine that will be less susceptible to noise and vibrations, it could be a great option. The turbocharger in the 5. It uses high injection pressure to give the most precise control of the in-cylinder combustion. This leads to superior fuel efficiency and almost zero emissions. Just because the 5. It still delivers stock horsepower and lb-ft of torque due to the fuel system and the Two-Stage turbo.
If you are looking for a good balance between performance and comfort, this could be the best Cummins engine for your truck. Load More. Share this. Share 0. Tweet 0. At , miles, the engine needs its closed crankcase ventilation filter replaced as well as an ignition coil extension.

Curious about this natural gas engine? Read the brochure. The Performance is the version of the more powerful models of Productivity. While lower horsepower Productivity engines integrate the hardware set of the Efficiency, the only notable difference between the Performance and the stronger variations of Productivity is the age of the engine.
Check out the webpage for the X15 Performance and compare the specifications. Part of the x15 efficiency series engines, in a brighter shade of red than its counterparts. It has 20 total variations: 8 standard, 6 SA, and 6 ST.
The engines are nearly identical to their counterparts. See the brochure for more details. Back in , engines were not split into Efficiency, Performance, or Productivity. Because of the engine types fit into one immediate family, it is not surprising that the ISX15 has the most variations of all the Cummins engines we have looked at thus far. With 17 standard, 11 SmartTorque, seven SmartTorque2 the next generation of SmartTorque , and four vocational models which have higher torque in the lower gear ranges , that makes a total of 39 different engine versions!
The ISX15 has extended coverage plans for up to 7 years or , miles, but today that is not helpful. Working in all forms of commercial vehicles, the ISX12 is an older model of the smaller engine.
There are 20 variations: eight normal, four SmartTorque, and eight Vocational. Read up upon all things ISX12 at its webpage. Duramax differences and similarities and to decide which is right for you! Their high horsepower and torque outputs directly compete with Cummins engines, as well as PowerStroke. In addition to durability, Duramax engines are known for their quiet performance. Cummins engines are known for their power, reliability and durability, and are frequently found in hard-working commercial vehicles.
The current incarnation is the Cummins 6. There are some slight differences in power, based on the truck body style:.
If you do end up choosing a model with a Cummins engine, you may need to know how to identify an Aisin transmission. The right engine for you depends on the type of truck you need.

It was in when a Cummins Turbodiesel made its way into a Ram pickup — and the legend began. The powerful engine blew competition from Ford and GMC out of the water. Cummins began to dominate the market when it came to diesel engines for the automotive industry because of its reputation for longevity. The crankshaft and the connecting rods are forged steel along with massive main bearings.
Instead of the timing chain or belt that is used in gasoline engines, the diesel engines use a steel time gear connected to the crank and cam. All-in-all, the Cummins diesel engine is a beast that is not willing to die.
