The RAM 2500/3500 Crew Cab Long I, specifically the facelifted version produced from 2013 to 2018, represented a significant evolution in the heavy-duty truck segment. This generation, internally designated as the DJ/D2 platform, built upon the foundation laid by its predecessors, offering increased capability, refinement, and technology. The 2500 model, equipped with the 6.7-liter Cummins turbodiesel engine producing 370 horsepower and paired with a six-speed automatic transmission, and a 4×4 drivetrain, occupied a sweet spot in the lineup, balancing robust performance with everyday usability. It was positioned as a workhorse for those needing substantial towing and hauling capacity, but also desiring a comfortable and well-equipped cabin for both work and family use.

Powertrain & Engine Architecture
The heart of this RAM 2500 variant is the 6.7-liter Cummins inline-six turbodiesel engine. This engine, designated as the ETJ code, is a robust and highly regarded powerplant known for its durability and torque output. It features a cast iron block, aluminum cylinder head, and a 24-valve OHV (Overhead Valve) configuration. The engine utilizes a Bosch common-rail fuel injection system, delivering precise fuel metering for optimal combustion and efficiency. A variable geometry turbocharger (VGT) with an intercooler further enhances performance by providing increased air intake. The six-speed automatic transmission, sourced from Aisin, was specifically designed to handle the Cummins engine’s substantial torque. It features electronically controlled shifting and tow/haul mode for improved performance when towing heavy loads.
Driving Characteristics
The 370 horsepower and 1084 lb-ft of torque delivered by this powertrain combination resulted in impressive performance. While not as quick as some of the gasoline-powered RAM 2500 models, the Cummins diesel offered a significantly higher towing capacity and superior low-end grunt. The automatic transmission, while smooth, was tuned for durability and efficiency rather than outright speed. Gear ratios were optimized for towing and hauling, meaning acceleration was brisk but not exhilarating. Compared to the higher-output Cummins variants (like the 420 hp version), this 370 hp engine provided a more manageable power delivery, making it easier to control when towing or navigating challenging terrain. The 4×4 system provided excellent traction in various conditions, making it a capable off-road performer as well.
Equipment & Trim Levels
The 2500/3500 Crew Cab Long I with the 6.7L Cummins and automatic transmission was typically offered in several trim levels, including SLT, Laramie, and Limited. The SLT trim served as the entry point, offering standard features like air conditioning, power windows and locks, a basic audio system, and vinyl upholstery. The Laramie trim added more luxurious appointments, such as leather upholstery, heated front seats, a premium audio system, and chrome exterior accents. The Limited trim represented the pinnacle of luxury, featuring premium leather, wood trim, a navigation system, and a host of advanced safety features. Optional extras included a sunroof, rear-seat entertainment system, and various towing packages.
Chassis & Braking
The RAM 2500/3500 featured a robust chassis designed to withstand heavy loads. The front suspension utilized an independent multi-link setup, providing a comfortable ride and improved handling. The rear suspension also employed a multi-link design, enhancing stability and reducing axle hop. Braking duties were handled by four-wheel disc brakes with ABS (Anti-lock Braking System). Larger brake rotors and calipers were often included with higher trim levels or as part of a heavy-duty towing package. The frame itself was fully boxed, providing exceptional strength and rigidity.
Market Reception & Comparison
The 2500/3500 with the 6.7L Cummins and automatic transmission was well-received by critics and consumers alike. It was praised for its powerful engine, comfortable ride, and spacious cabin. Fuel economy, while not a primary concern for truck buyers, was respectable for a vehicle of this size and capability. Compared to the gasoline-powered RAM 2500 models, the Cummins diesel offered significantly higher towing capacity and better fuel efficiency when towing. However, the diesel engine came with a higher initial cost and potentially higher maintenance expenses. Compared to other heavy-duty trucks in its class, such as the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM 2500/3500 was often lauded for its refined interior and comfortable ride.
Legacy
The 6.7L Cummins engine, in general, has earned a reputation for exceptional reliability and longevity. With proper maintenance, these engines can easily exceed 200,000 miles. The automatic transmission, while not as bulletproof as some older transmissions, has also proven to be relatively reliable. In the used car market, these RAM 2500/3500 models remain highly sought after, particularly those that have been well-maintained. The combination of power, capability, and comfort makes them a popular choice for those needing a heavy-duty truck for work or recreation. The 2013-2018 facelifted models are particularly desirable due to their updated styling and improved features.
