How Much Does A Cummins 5.9 Diesel Weigh?

Buyers agree that the classic Dodge Ram is the best of the diesel truck variants. Rams have been the preferred truck of diesel drivers since the 1980s, because to their dependable Cummins engine and power. Over the last 50 years, the vehicle has seen numerous alterations, with some years being better than others.

1996-1998, 2006-2007, and 2010-2011 are the finest years for Dodge diesel trucks. Among Dodge diesel trucks, these years have the fewest complaints and the most capabilities. These trucks receive rave evaluations from owners for their hauling capability and dependability.

A thorough review of their benefits and cons is required to understand why these years are the best among so many makes of Dodge diesel engines. Let’s take a look at what the best years in history have to offer.

Due to its popularity, nearly 2 million 7.3 Power Stoke engines were produced from International’s Indianapolis plant.

Ford coined the term “Powerstroke” to describe its diesel engine lineup. The 7.3-liter powerstroke is a Navistar T444E, manufactured by Navistar International (previously International Harvester). The 7.3 is used in school buses, transit buses, and other large commercial vehicles, in addition to Ford Super Duty trucks.

It has a 17.5:1 compression ratio.

The compression ratio is the difference between the volume of air in the cylinder when the piston is at the bottom of the stroke vs when it is at the top of the stroke. Higher compression ratios enable more power to be produced while lowering exhaust gas temperatures. The higher the compression, the hotter the air inside the cylinder is, requiring less fuel to ignite and produce combustion.

Because the 7.3 Powerstroke uses glow plugs rather than spark plugs, higher compression ratios are required to raise air temperatures sufficiently for ignition to occur. The 7.3’s compression ratio is comparable to that of the Duramax and Cummins engines of the period.

The 7.3 Liter Power Stroke has a dry weight of approximately 920 lb (420 kg).

This engine is the largest mass production diesel engine at 7.3 liters (not including commercial vehicles). It is also one of the largest production engines of its time, trailing only the Bugatti Veyron’s 8.0L 16-cylinder engine and the SRT Viper’s 8.4L V10 engine in terms of displacement.

Surprisingly, it weighs less than the Cummins 5.9L V6 12v of the time and its replacement, the 6.0 Powerstroke, at 920 pounds.

From the factory, the 7.3 Power Stroke engines produced up to 250 hp (190 kW) and 505 lb·ft (685 N·m) of torque in automatic-transmission trucks during the last years of production, and 275 hp (205 kW) and 525 lb·ft (712 N·m) of torque in manual-transmission trucks.

While these statistics may be poor by today’s diesel power standards, the powerstroke held its own against its competition. The 7.3 can easily add 100whp for less than $2,500 for customers desiring extra power.

In 1999, an air to air intercooler was added to cool the charged air from the turbo for increased air density.

Due to the inclusion of an intercooler and higher-flowing injectors, 7.3 powerstrokes from 1999 to 2003 had dramatically improved performance potential. Take a look at our list of the top 7.3 Powerstroke mods available.

The 7.3 Power Stoke utilizes a cast iron block and cast iron cylinder heads.

This monster is a hefty lump of iron at 7.3L. It’s partly due to the size of the engine block that your 7.3 takes a long time to start in cold weather. The glow plugs have to work extra hard to light up the 7.3 in cold weather since cast iron blocks have superior durability but poor heat transfer.

It utilizes a single turbocharger with a turbine housing size of 1.15 A/R.

From 1994.5 until 1997, the turbo used a fixed geometry Garrett TP38 with no wastegate. In 1999, the TP38 was improved to include a wastegate in addition to the intercooler. In 1999.5, the 7.3 turbo was modified once again to the Garrett GTP38 wastegated turbo.

The 7.3 Power Stroke is based on International’s T444E engine (the name “Power Stroke” is unique to Ford vehicles)

Ford’s diesel engines in its Super Duty vehicles are marketed under the name Powerstroke, or formally “Power Stroke.” The engines were made by International Harvester, which was renamed Navistar International after a restructuring in 1986. Navistar is currently owned by Volkswagen.

Following the dangerous 6.0 and 6.4 powerstroke engines, Ford severed their ties with Cummins and began producing the Power Stroke in-house, beginning with the 6.7.

Production of the 7.3 Liter Power Stroke engine ceased in 2003 in order to meet emission regulations.

Diesel engine variations had relatively limited life cycles during the 2000s. As emissions rules become increasingly stringent, diesel engines must continually innovate to become more environmentally friendly. Diesel emissions rules are the reason modern diesels have advanced systems like DPF, SCR, and DEF, among others.

The lack of emissions equipment is one of the reasons the 7.3’s are still so valued today. Diesel emissions systems have a reputation for being difficult and expensive to fix, prompting many owners to either remove the emissions systems or look for older diesel trucks.

Fuel for the 7.3 Power Stroke engine is provided by Direct injection, HEUI (hydraulic electronic unit injection) Injectors.

While the HEUI system is no longer in use in favor of more advanced injection systems, it was a technological marvel at the time. The HEUI technology allowed the 7.3’s injection system to pressurize diesel fuel at 7 times the pressure of the oil. Without going into technical details, there were various advantages to the HEUI system:

  • When compared to traditional camshaft control, electronic control provides more flexibility and control over injection events.
  • Injector pressure was increased to 21,000psi, compared to less than 5,000psi for Cummins and Duramax engines at the time.

Is 24v better than 12v Cummins?

For bone stock performance, the newer ISB 5.9 24v Cummins wins. Beginning in 1998, ISB engines produce 235 horsepower and 460 pound-feet of torque. Only a little upgrade over the previous Cummins 6BT 12 valve. The Ram ISB 5.9 diesel, on the other hand, acquired common rail fuel injection in 2003. This helped improve power to 305 horsepower and 555 pound-feet of torque. A year later, this was boosted to 325 horsepower and 600 pound-feet of torque.

Of course, years of scientific and engineering advancements have enabled newer engines to perform better. When comparing the performance of the 12v and 24v Cummins engines, the later 24v engines are unquestionably superior. That isn’t to imply that the 12v Cummins isn’t capable.

v vs 24v Tuning & Aftermarket Potential

The 24v engine is still the preferable alternative for individuals wishing to keep things simple with a tune and modest bolt-ons. It’s a lot easier to tune because the electronics support “chip” tunes. The VP44 injection pump, on the other hand, is a big stumbling block for anyone wishing to push the engines to their limits.

The 12v 5.9 Cummins wins when it comes to significant power and performance. When compared to 24v engines, these engines are renowned to keep up better at high power levels. On the 6BT, the P7100 injection pumps are easy to modify and support the extra power.

In conclusion, the 24v is the best street engine for individuals who want to keep things simple or modest. The older 12v Cummins engine is likely the superior choice if you’re searching for high power and performance. Getting any engine or transmission to 600+whp isn’t cheap, though.

Are 24v Cummins reliable?

The 5.9 24v is a fairly reliable engine outside of the fuel system. The engine internals, such as the pistons, rod, and crankshaft, are designed to last a lifetime and can withstand more than 500,000 miles of use. Aside from the fuel system, you should plan to replace basic elements like water pumps, hoses, and belts over your ownership. Due to the lack of emissions-related systems, maintenance is often extremely easy and economical outside of these components.

The turbo, which is a common source of failure on diesel engines, is extremely durable. However, because it is not a particularly powerful turbocharger, many people opt to improve it when looking for considerable power gains.

About half of these engines will live for more than 350,000 miles without a catastrophic failure, making them extremely dependable. Just keep in mind that you’ll almost certainly need to replace some pricey fueling components before you get that level of mileage.

Did Cummins ever make a V8?

Between the lesser and larger diesel alternatives in the pickup market, the 5.0L V8 Turbo Diesel stands out. The 5.0L V8 Turbo Diesel combines a compacted graphite iron (CGI) cylinder block with a forged steel crankshaft, high-strength aluminum alloy heads, and composite valve covers to provide optimal durability in a lightweight package. These elements, together with twin overhead camshafts, contribute to the 5.0L V8 turbo diesel’s excellent noise, vibration, and harshness (NVH) characteristics.

Fuel-Efficient Turbocharger

The Cummins M2TM Two-Stage Turbocharger is designed to operate efficiently at both low and high engine speeds. The latest Bosch High Pressure Common Rail (HPCR) fuel system and piezo fuel injectors deliver precise fuel control for enhanced in-cylinder combustion, resulting in improved fuel efficiency and lower emissions. The HPCR fuel system, in conjunction with the Cummins M2TM Two-Stage Turbocharger, provides to a very high peak torque of 555 lb-ft and 310 horsepower, thanks to multiple injection events controlled by integrated electronic controls.

Advanced Ceramic Glow Plugs

The innovative ceramic glow plug technology minimizes start time and electrical current draw in cold conditions, lowering vehicle charging system requirements. The ceramic glow plugs are made to last the entire life of the engine and require no maintenance.

Two-Stage Fuel Filtration

The latest NanoNetTM media from Cummins Filtration is used in a two-stage fuel filter system for the 5.0L V8 Turbo Diesel to ensure that the HPCR fuel system is fully protected against fuel contamination. NanoNet’s innovative design allows for higher fuel flow and catches more than 99 percent of all particles as small as 4 microns.

Near-Zero Emissions

Cummins’ considerable emissions technology experience is used to create proven air handling and emissions control solutions. Cummins M2TM Two-Stage Turbocharger, cooled Exhaust Gas Recirculation (EGR), and Cummins Emission Solutions Aftertreatment System, which includes a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR), produce near-zero NOx and PM emissions while improving performance and fuel economy.

Does Ford own Cummins?

It’s a popular misconception that Cummins is owned by car companies such as Ford or Chrysler. Cummins Turbo Technologies, in fact, is a separate firm that designs, manufactures, and sells a whole range of diesel and natural gas engines.

How many miles will a Cummins 5.9 last?

Cummins engines are one of the most common diesel pickup truck engines. If you’re thinking about buying a new or used truck with a Cummins engine, you should find out how long it’s expected to survive. To find out for you, we looked through forums and the Cummins website.

The Cummins brand is known for its dependability and long-lasting engines. The 5.9-liter engine should last between 300,000 and 400,000 miles. With no modifications and adequate maintenance, the 6.7-liter engine costs around 350,000 dollars.

Diesel engines are designed to be powerful and provide a lot of power. You’ll be able to haul more, achieve better fuel economy, and have peace of mind. We’ll go over the differences between the 5.9L and 6.7L Cummins engines, as well as why Cummins engines are so popular.

How many MPG does a 5.9 Cummins get?

My youngest brother got a new 3500 Ram daully with a 5.9L Cummins engine in 2004 and showed it to my father. My father then went out and got a new 2004 2500 Ram with a 5.9L Cummins engine, which he showed me. Unfortunately, I was just getting back on my feet after being laid off for three years, so I returned to work and saved everything I could until late 2006, when I purchased my first new Dodge 2500 Ram with the 5.9L Cummins engine. Since 2006, I’ve bought my wife two trucks: a new 2008 Dodge 2500 Ram with a 6.7L Cummins engine and a 1999 Dodge 2500 with a 6.7L Cummins engine (which has a 6 inch lift, racing trans, Smarty Tuner, modified straight pipe, and custom rims). I still have the 2006, but I sold the 2008 because it was equipped with a 6.7L Cummins engine. In 2012, I came upon a 2001 Dodge Ram 2500 with 39,900 original miles and a 5.9L Cummins engine. In 2010, I purchased a 2002 Dodge 2500 Ram with a 5.9L Cummins engine for each of my two college-aged boys. We upgraded one truck with the same racing transmission overhaul as my wife’s ’99, along with a Smarty Tuner, to increase RWHP to 410 and torque to 700 foot-lbs. Needless to say, the 5.9L Cummins has won us over. The vehicles have excellent fuel efficiency after our modifications, air intake upgrades, and exhaust straight pipe swaps. We have five Dodge 4×4 pickups with the 5.9L Cummins engine, and we love them all. We get 29 miles per gallon on the freeway and 24 miles per gallon in town with the five trucks we own. The Cummins 5.9L has the fuel economy, speed, and pulling power to get the job done. We only drive Cummins 5.9L engines, and we couldn’t be happier with the results!

Here are some of my suggestions for keeping our trucks in top shape!


In the stock air intake, install a K&N filter.

Change the oil in the box on a regular basis. Maintain spec levels for all fluids.


Remove the “silencer ring” from the “silencer ring” in the “silencer ring” in

Use a MADS Smarty Down Loader, but not a MADS Smarty Down Loader.

Stock trans is suggested. Take note of this:

Only if the trans has been upgraded/rebuilt with more ft.-lbs. is it smart:

capacity of over 700 ft-lbs, as well as a heavy-duty Billet Shaft, etc., otherwise you risk damaging the machine.
