When it comes to building dependable trucks, Ram has a troubled history. Dodge has a good chance of producing a good Ram truck. The Cummins Turbodiesel inline-six in the 2007 Ram 2500 produced 650 lb-ft of torque and, with a manual transmission, could actually light up the tires. Other models had a slew of issues, with 2014 being the worst year for Ram, according to customer complaints.
There were fifteen recalls made for the 1500, ranging from engine fires to a cruise control system that was not cooperating. If you’re looking for a Ram truck, it’s better to stay away from these model years.
What year Dodge Ram diesel is the best?
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.
Is 5.9 or 6.7 Cummins better?
When the 6.7 Cummins diesel first appeared in the 2007 Dodge Ram diesel pickups, it superseded the 5.9 Cummins diesel. The 6.7 engine had great hopes, as the 5.9 engine was known for its long-lasting performance and ability to resist high mileage. If the 5.9 was good, the 6.7 must be much better, right?
The core parts of the 5.9 Cummins were carried over to the 6.7 Cummins, which meant it was off to a good start because the 5.9 Cummins had a reputation for solid performance and a wide range of aftermarket parts and servicing.
The 6.7 Cummins comes with a comprehensive set of emissions control elements, the majority of which are not available on the 5.9 Cummins. An EGR (exhaust gas recirculation) system, a DOC (diesel oxidation catalyst), a NAC (NOx absorption catalyst), a DPF (diesel particulate filter), and, starting in 2013, an SCR (selective catalytic reduction) system are among these components (selective catalytic reduction). The SCR became standard in Cummins 6.7L engines after that.
Because of the EPA’s rigorous criteria, emissions control devices are required for modern diesel engines like the 6.7. Unfortunately, they do have an impact on performance.
The engine achieves a hotter combustion temperature without EGR, allowing it to burn fuel more thoroughly. This reduces particulate matter while increasing NOx output (Nitrogen Oxide). The issue with producing more NOx is that it causes excessive carbon buildup, which causes engine oil and coolant to degrade. The 5.9 did not have an EGR system, unlike the 6.7, and this likely contributed to its reputation for longevity, even with high miles on the engine.
In comparison to the 5.9 Cummins, the 6.7 Cummins produces a lot of torque at low RPM. This is due to the longer stroke in the 5.9 Cummins, which is 4.72 inches vs. 4.88 inches in the 6.7 Cummins.
Increased low-end torque translates to greater towing capability, so it’s easy to understand why this is a plus. However, it also implies that the cylinders will be under higher pressure. Head gasket failure, which is a typical problem on the 6.7 Cummins, can be caused by increased cylinder pressure. The 5.9 Cummins, on the other hand, experienced very few head gasket problems.
By 200,000 miles, a 6.7 Cummins that is regularly used to tow is likely to have head gasket troubles. Head gasket problems might occur considerably sooner in modified engines with performance enhancements. Another factor contributing to head gasket failure on the 6.7 Cummins is the smaller sealing gap between the water jackets and cylinders due to the bigger bore.
The fixed geometry turbo on the 5.9 Cummins varies from the variable geometry turbo on the 6.7 Cummins. With a 58mm compressor wheel, internal wastegate, and 58mm turbine wheel, the fixed geometry turbo on the 5.9 is a straightforward design. It has a reputation for being exceptionally sturdy and long-lasting as long as it does not receive a boost of 45 psi or higher on a regular basis.
However, because of the fixed shape design, you’ll most likely have low RPM turbo lag. There is no wastegate on the 6.7 Cummins turbo system, and the compressor wheel is 60mm in diameter. The turbine wheel’s exhaust flow varies, allowing the system to respond more quickly at lower speeds. There is no turbo latency, and it operates as well as a larger turbo unit at high RPMs.
To summarize, while the more basic 5.9 fixed geometry turbo is more reliable, the more complex 6.7 variable geometry turbo provides superior performance.
The Exhaust Brake is a significant reason why the Cummins 6.7 is such a strong towing machine. The exhaust brake is a device that produces a restriction in the exhaust system, resulting in significant backpressure, which reduces engine speed and provides additional braking. On this engine, using the exhaust brake at all times helps prevent the sticking turbo issue that is typical on these engines.
The 6.7 turbo system’s variable geometry design provides for forceful braking. This reduces the amount of wear on a truck’s standard brakes significantly. Braking ability is also an important part of towing ability.
Only part of the equation is being able to draw a large load. You must also be capable of stopping a heavy load. The variable geometry design’s aggressive exhaust braking capability provides for effective and powerful deceleration. As a result, the 6.7 Cummins-powered Rams are among the best in the hauling category.
The Bosch high-pressure common-rail fuel injection system is used in both the 5.9 and 6.7 Cummins engines. The injectors in the 6.7 Cummins, on the other hand, are rated for higher pressure and are specifically engineered to withstand it. They also use less electricity to operate.
Each injector in the 6.7 has been programmed to prevent them from switching between cylinders. On the other hand, the 5.9 Cummins engines allow for cylinder swapping. Injectors with a higher pressure allow for additional torque and power.
When an engine is running at high RPMs with full load, combustion duration is limited. The 6.7’s higher-pressure injectors pump fuel into the engine fast, resulting in maximum power.
In conclusion, the 6.7 Cummins outperforms the 5.9 Cummins in practically every category. It also emits less pollutants that are hazardous to the environment. The 5.9 Cummins, on the other hand, is a simpler piece of technology that provides near-unbeatable reliability, even in high-mileage trucks.
You can make an informed decision about whether you want to go with the latest diesel technology or remain with an older, but still highly durable engine now that you know the primary distinctions between the 5.9 and 6.7 Cummins engines. Whichever option you choose, ProSource offers the Cummins diesel components you need to get the most out of your truck’s performance and endurance.
What year Dodge Rams to stay away from?
The 2014 RAM 1500 was the first vehicle to use the new EcoDiesel engine, and it had some issues. It’s inevitable that the initial release of anything will have the greatest issues, and this one certainly did. For the 2014 models, there were 14 recalls; not all of them had engine faults, but the majority were engine-related in some way.
The transmission was the most problematic aspect of the year’s transition to the EcoDiesel engine. Owners have reported the transmission not downshifting correctly, being noisy at cold starts, being noisy at low speeds, shifting out of drive while driving, rpm without acceleration, and a jolt in the transmission while releasing the brake or accelerating. Many of them may appear to be trivial issues, and they may be, but they could be signs of a transmission breakdown.
Dodge RAM 1500
Electrical, gearbox, engine, and fuel system recalls accounted for 14 of the total. These issues are still mostly linked to the failure of RAM’s new EcoDiesel engine architecture.
Other issues that became common complaints included RAM’s GPS/UConnect system failing, radio issues, dashboard warning light issues, and screen display issues. Unfortunately, many of these problems are like the boogeyman: most technicians don’t know why they happen, so they come up with a temporary fix/repair, and the problem reappears.
There were 11 recalls for the 2016 RAM 1500, which were still dealing with issues in the EcoDiesel. The RAM 1500 had various issues, such as a broken rear tailgate latch on vehicles with power locks, in addition to the engine, which was less powerful than prior years. Other problems with this RAM included the shifter linkage, cruise control, and airbags.
Here Are The Dodge RAM 1500 Years to Look For: 2011, 2017
Dodge RAM vehicles have had the fewest difficulties and owner complaints in recent years. You may have a low-maintenance truck that lasts a long time if you can find one in decent shape.
How to Shop for a Used Dodge RAM in Your Area
Trucks are perhaps the most straightforward vehicles to purchase. Your biggest concern will always be how many miles the truck has on it, how well it has been maintained over those miles, and how bad the rust is.
There are two types of truck drivers: those who treat their vehicle as if it were a member of their family and those who handle it as if it were a workhorse. It’s great either way; it’s just those guys who treat their pickups like mules who are the problem. Those trucks must be fairly worn out, right? Guys who treat their trucks as if they were members of their family are the ones you can trust; they’ll survive as long as you keep them maintained.
When purchasing a used truck, you should be prepared to deal with surfaced rust. Rust is a common occurrence on fenders, rocker panels, and tailgates. It’ll be up to you to decide how much rust is on a truck and how much rust you want to cope with. Remember that rust rarely goes away; in fact, it often grows, especially on vehicles.
Low Miles and Well-Maintained
Here are the years to look for in a Dodge RAM 1500: 2011, 2012, and 2017 are the years. Even if some models have a lot of miles on them, you might want to take a chance on them if you discover a reasonable offer and can verify the truck has been well-maintained.
Here are some Dodge RAM 1500 years to stay away from: 2003, 2010-2013 (5.7-liter V8), 2014, 2015, 2016 (5.7-liter V8), 2014, 2015, 2016. However, just as the years before it, something well-kept may offer you something worthwhile to acquire; just be aware of what you’re getting yourself into.
What problems does the 6.7 Cummins have?
The following are some of the concerns that may arise with the 6.7 Cummins turbo: Oil seals that are leaking. Bearings that have been worn out (too much shaft play) Gluing VGT pieces together. 6.7 Diesel Turbo Failure Symptoms in Dodge and Ram
Is a 12 valve Cummins better than a 24 valve?
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.
Which is better Duramax or Cummins?
The Cummins engine is currently a 6.7-liter inline-six, whilst the Duramax is a 6.6-liter V8. The Duramax is the most powerful engine in terms of horsepower, but the Cummins is the most powerful in terms of torque, with values up to 1,000 ft-lbs depending on the truck.
What year did Dodge switch to 6.7 Cummins?
Cummins introduces high-output engines, however only the NV5600 manual transmission is available in California.
The 6.7L Cummins engine was launched in the middle of the model year as a replacement for the 5.9L; it fulfills stricter pollution rules and comes standard with a diesel particulate filter (DPF).
In February of 2011, Cummins and Ram Trucks introduced a higher-output 800 lb-ft engine.
For the 2013 model year, Cummins offers three transmission options: G56 manual, 68RFE automatic, and Aisin automatic. Only Ram 3500 pickups with the High Output (H.O.) variant and Aisin transmission are available. On all Cummins engines, selective catalytic reduction (SCR) with the use of diesel exhaust fluid (DEF) becomes standard.
The Cummins High Output (H.O.) engine, mated to the Aisin transmission, boosts torque output by 15 lb-ft and is only available on Ram 3500 vehicles.
For the 2016 model year, H.O. Cummins gets 35 lb-ft, bringing peak torque to 900 lb-ft. The high-output engine is only available in Ram 3500 trucks with the Aisin AS69RC automatic transmission.
H.O. Cummins gains 15 horsepower and 70 lb-ft of torque, peaking at 1,000 lb-ft. There is no difference in horsepower, but the standard Cummins gains 50 lb-ft. There is no longer a manual transmission option.
The H.O. Cummins engine gains 20 horsepower and 75 pound-feet of torque. The standard Cummins output stays unchanged from prior model years. The Bosch CP4 injection pump has been phased out in favor of the more reliable Bosch CP3.
What year did Dodge start using 6.7 Cummins?
The 6.7L ISB Cummins, which debuted midway through Dodge’s Ram line’s 2007 model year manufacturing, claimed 350hp and 650 lb-ft of torqueas long as you were willing to let the all-new 68RFE six-speed automatic shift gears for you. Dodge had long recognized that the truck market was shifting toward automatic transmissions, so it began to scale back its manual gearbox research and development. The lower factory torque ratings given with the Mercedes Benz-sourced G56 gearbox option are a direct result of this. The Cummins’ higher output version would never again be available with a manual transmission.
Is the 6.7 Cummins a million mile engine?
Do you want to know how many miles a 6.7 Cummins gets on average? Perhaps you’re looking for a pre-owned Ram truck? Is a used 6.7 Cummins with over 200 miles still considered safe?
The Cummins 6.7 engine, according to Ram, is guaranteed for 350,000 kilometers. The mileage is guaranteed if all scheduled services are completed on time and the engine has not been modified for performance.
These engines are regarded as one of the three most reliable engines ever created, and they are frequently compared to competitors such as Isuzu Motors’ Duramax and Ford’s Powerstroke engines. A detailed oil examination is recommended if you want to determine the general condition of the engine before acquiring a used truck with this mileage.
Without requiring any considerable engine work, this will be able to provide particular clues regarding engine wear rate. You can determine the quantity of pollution and overall engine health by evaluating a sample of used engine oil.
Let’s take a look at some of the high-mileage components that will need to be inspected as the big 6.7 Cummins hits hundreds of thousands of miles.
What year is the most reliable Ram 1500?
The 2017 Ram 1500 has proven to be the greatest year and least problematic of the fourth-generation trucks during the last decade. The nine recalls, which include tailgates that open while driving, a faulty transmission interlock pin, and a few of repairs for the 3.0L diesel engine, should have been completed by now.
With 14 trims to choose from, you’ll be able to pick a vehicle that can get down and dirty or chauffeur you around town in style. Jake Holmes at Motor1 was completely smitten by the Night Edition. “It reminds me how much I like any version of the Ram 1500,” he said after taking it for a ride.
It embraces its dark and powerful side, starting with its 20-inch black wheels, black light bezels, and black badging. The 5.7L Hemi engine and sport-tuned exhaust offer plenty of power, and the air suspension actually helps the truck sag down for better aerodynamics when cruising at high speeds.
