Do Dodge 2500 diesel and Dodge 3500 have the same motor?


When comparing the Dodge Ram 2500 and Dodge Ram 3500, two of the most popular heavy-duty trucks on the market, one common question arises: do they share the same motor? As an experienced auto service provider, I’ll break down the similarities and differences between these two models to help you better understand their engines and performance capabilities.


Shared Engine Options


Both the Dodge Ram 2500 and Dodge Ram 3500 are equipped with similar engine options, particularly when it comes to diesel powertrains. The most notable shared engine is the legendary 6.7L Cummins Turbo Diesel. This engine is renowned for its durability, towing capacity, and fuel efficiency, making it a favorite among truck enthusiasts and professionals alike.


Here are the key specifications of the 6.7L Cummins Turbo Diesel engine:



  • Inline-six-cylinder configuration

  • High torque output, ideal for towing and hauling

  • Available in multiple power levels depending on the truck's configuration


Differences in Engine Tuning and Performance


While the Dodge Ram 2500 and 3500 may share the same 6.7L Cummins engine, there are differences in how the engine is tuned and configured for each model. These differences are primarily due to the varying roles these trucks are designed to fulfill:



  • Dodge Ram 2500: The 2500 is typically tuned for lighter-duty applications compared to the 3500. It offers a balance of power and comfort, making it a great choice for those who need a capable truck for towing and hauling without venturing into extreme heavy-duty territory.

  • Dodge Ram 3500: The 3500, on the other hand, is designed for maximum towing and payload capacity. It often features higher torque outputs and may include additional upgrades, such as dual rear wheels (dually) for enhanced stability and load-bearing capabilities.


Gasoline Engine Options


In addition to the diesel engine, both the Ram 2500 and 3500 also offer gasoline engine options. These include the 6.4L HEMI V8, which provides robust performance for those who prefer a gas-powered truck. Like the diesel engine, the gasoline engine is shared between the two models but may have slight variations in tuning and performance depending on the truck's configuration.


Conclusion


In summary, the Dodge Ram 2500 and 3500 do share the same motor options, including the 6.7L Cummins Turbo Diesel and the 6.4L HEMI V8. However, the way these engines are tuned and configured can vary between the two models to meet their specific performance and capability requirements. If you’re deciding between the two, consider your towing and hauling needs, as well as whether you prioritize comfort or maximum power.

Frequently Asked Questions

Which 6.7 Cummins to avoid?


We recommend staying away from the 1991, 1992, 1993, 1999, 2001, 2003, 2006, 2007, 2008, and 2011 models. Many issues stem from these years. A few of the common appear in the format of transmission failure, charging system troubles, and electrical issues. These can be costly to handle and inconvenient for any driver.



What's the difference between the 6.7 Cummins and the 6.7 Cummins high output?


In addition to the 50 extra horsepower and the 225 lb-ft of torque gains, the HO Cummins is backed by a better transmission. The SO 6.7 Cummins comes equipped with the Chrysler 68RFE transmission, whereas the Aisin AS69RC transmission handles shifting duties in the HO-equipped Ram 3500 powertrain.



What is the difference between 5.9 and 6.7 Cummins?


The 6.7 Cummins features a variable geometry turbo, which is different from the fixed geometry turbo on the 5.9. The fixed geometry turbo is a simple system, which consists of a 58mm compressor wheel, an internal wastegate, and a 58mm turbine wheel. This system had a reputation for being durable and long-lasting.



Is a 6.7 Cummins better than a 6.6 Duramax?


If towing capacity is your top priority, the Cummins diesel engine has a slight advantage. Thanks to its immense torque, the Cummins engine allows Ram trucks to achieve a higher maximum towing capacity compared to Duramax-equipped trucks.



What's the difference between a 2500 diesel and a 3500 diesel?


One of the biggest differences is that with the much wider chassis with the 3500HD with available dual rear wheels this truck is capable of towing much more weight. The dual rear wheels deliver much more power to the pavement. While the 2500 HD is capable of towing up to 18,510 lbs. the 3500HD can tow up to 36,000 lbs.



What year RAM 2500 to stay away from?


General Buying Advice: Avoid The 2013-2018 Model Years
As such, if you're in the market for the most reliable RAM 2500 year, skip the 2013 to 2018 models because they're riddled with reliability woes, recalls, and complaints. For example, the 2013 model year doesn't quite hit the landing in reliability.



Does a 3500 have more power than a 2500?


While the RAM 2500 and 3500 offer the same numbers for horsepower and torque for both engines, the RAM 3500 offers much higher towing and payload capabilities no matter which engine you choose. The RAM 3500 also has the advantage of a third engine choice for some model years–a high-output variant of the diesel engine.



Does the Ram 2500 and 3500 have the same engine?


The Ram 2500 and Ram 3500 are both available with three engine options, the 5.7L HEMI V8, the 6.4L HEMI V8 engine and the 6.7L Cummins Turbo Diesel engine. However, the Ram 3500 is the only model that is available with an improved 6.7L Cummins Turbo Diesel engine that can produce up to 930 lb-ft of torque.



What is the problem with the RAM 3500 Cummins?


RAM 3500 trucks, especially those using the 6.7L Cummins engine, have been plagued by a range of engine-related issues. Common complaints include engine stalling while driving, misfires, and excessive oil consumption.



Why can a Ram 3500 tow more than a 2500?


With an astounding 1,000 lb-ft torque, the Ram 3500 towing capacity is an impressive 35000 lbs., which boosts the owner's towing needs. Ram 3500 supports a payload of 7682 lbs. It has a 6.7L Output Cummins Turbo Diesel engine with 400 hp, which makes it slightly stronger and mightier than Ram 2500.
