Powertrain & Engine Architecture
The heart of this RAM 2500/3500 variant is the 6.7-liter Cummins inline-six diesel engine, designated with the ETJ code. This engine is a robust and well-respected powerplant known for its longevity and torque output. The 6.7L Cummins utilizes a cast iron block and head, contributing to its durability. The engine employs a diesel common rail fuel injection system, delivering highly pressurized fuel directly into the cylinders for efficient combustion. The turbocharger, coupled with an intercooler, forces more air into the engine, boosting power and torque. The overhead valve (OHV) valvetrain, while a more traditional design, is known for its simplicity and reliability. The six-speed manual transmission was a popular choice for those who preferred greater control over gear selection, particularly when towing or hauling heavy loads. The transmission’s gear ratios were optimized to maximize the engine’s torque, providing strong acceleration and pulling power.
Driving Characteristics
The 6.7L Cummins with the manual transmission delivered a distinctly truck-like driving experience. While not designed for outright speed, the engine’s substantial 881 lb-ft of torque provided effortless acceleration, even when fully loaded. The manual transmission allowed drivers to precisely control engine speed and gear selection, which was particularly beneficial when navigating challenging terrain or towing trailers. Compared to the automatic transmission options, the manual offered a more engaging driving experience and potentially better fuel economy, although the difference wasn’t dramatic. The 350 horsepower output was sufficient for most heavy-duty tasks, but drivers accustomed to more powerful engines might find it somewhat lacking in certain situations. The suspension, tuned for heavy loads, provided a comfortable ride even when the truck was empty, although it could feel somewhat stiff compared to lighter-duty pickups.
Equipment & Trim Levels
The 2500/3500 with the 6.7L Cummins and manual transmission was typically offered in mid-range trim levels, such as the SLT or Laramie. Standard features generally included air conditioning, power windows and locks, a basic audio system, and vinyl upholstery. Optional extras could include leather upholstery, a premium sound system, navigation, a sunroof, and various towing packages. The Crew Cab configuration provided ample space for passengers, making it a popular choice for families and work crews. The long bed offered a generous cargo capacity, further enhancing the truck’s versatility.
Chassis & Braking
The RAM 2500/3500 featured a robust chassis designed to withstand the stresses of heavy-duty use. The front suspension utilized an independent multi-link design, providing a comfortable ride and good handling. The rear suspension also employed a multi-link setup, further enhancing ride quality and stability. Disc brakes were standard on all four wheels, providing ample stopping power even when the truck was heavily loaded. An anti-lock braking system (ABS) was also included as standard equipment, enhancing safety and control. The heavy-duty tires, typically sized 275/70R18 or 285/60R20, were designed to provide excellent traction and durability.
Market Reception & Comparison
The RAM 2500/3500 with the 6.7L Cummins and manual transmission was generally well-received by critics and buyers alike. It was praised for its robust powertrain, impressive towing and hauling capacity, and comfortable ride. Compared to the gasoline-powered versions of the RAM 2500/3500, the Cummins diesel offered significantly better fuel economy and torque. Compared to the automatic transmission options, the manual transmission was favored by those who preferred greater control and a more engaging driving experience. However, some critics noted that the manual transmission could be challenging to operate in heavy traffic.
Legacy
The 6.7L Cummins engine has earned a reputation for exceptional reliability and longevity. Many examples of this engine are still in service today, having accumulated hundreds of thousands of miles. The manual transmission, while less common than the automatic, is also known for its durability. In the used car market, these trucks hold their value relatively well, particularly those that have been well-maintained. The combination of a powerful diesel engine, a robust chassis, and a comfortable interior makes the RAM 2500/3500 Crew Cab Long I with the 6.7L Cummins a desirable choice for buyers seeking a capable and reliable heavy-duty pickup truck.
