The RAM 2500/3500 Crew Cab Long I, as updated with a facelift in 2013, represented a significant evolution in the heavy-duty pickup truck segment. Produced from 2013 through 2018, this generation built upon the foundation laid by its predecessors, offering increased capability, refinement, and a wider range of configurations. The 2500 model, equipped with the 6.7-liter Cummins turbocharged diesel engine producing 350 horsepower, occupied a sweet spot in the lineup, balancing robust performance with reasonable fuel economy for its class. This variant was particularly popular among those needing serious towing and hauling capacity without opting for the even more heavy-duty 3500 models.

Powertrain & Engine Architecture
The heart of this RAM 2500 variant is the 6.7-liter Cummins inline-six diesel engine, designated with the ETJ code. This engine is a robust and well-regarded powerplant known for its durability and torque output. The 6.7L Cummins utilizes a common-rail direct fuel injection system, delivering fuel at extremely high pressures for optimized combustion. The engine features an overhead valve (OHV) valvetrain, a design choice prioritizing low-end torque and simplicity. A variable geometry turbocharger and intercooler work in concert to boost power and efficiency. The 350 horsepower and 881 lb-ft of torque are readily available, making it ideal for demanding tasks. The 6-speed manual transmission was the standard offering, providing drivers with full control over the engine’s powerband.
Driving Characteristics
The 6.7L Cummins with the 6-speed manual transmission in the RAM 2500 delivers a driving experience focused on capability rather than outright speed. Acceleration is brisk, especially when considering the truck’s substantial weight. The engine’s torque curve is exceptionally flat, providing strong pulling power across a wide range of RPMs. The manual transmission allows for precise gear selection, enabling drivers to maximize engine braking when descending hills or towing heavy loads. Compared to higher-output Cummins variants, this 350 hp version offers a more manageable power delivery, making it easier to control in slippery conditions. While not as quick as gasoline-powered trucks, the diesel’s superior torque makes it far more effective for towing and hauling.
Equipment & Trim Levels
The 2500 Crew Cab Long I with the 6.7L Cummins typically came standard with a respectable level of equipment. Interior features included cloth upholstery, air conditioning, a basic audio system, and power windows and locks. The Crew Cab configuration provided ample space for passengers, making it suitable for families or work crews. Optional extras included leather upholstery, a premium sound system, navigation, a rearview camera, and various towing packages. Trim levels, such as SLT and Laramie, offered progressively more luxurious features and appointments.
Chassis & Braking
The RAM 2500/3500 chassis is built around a robust fully boxed frame, designed to withstand the stresses of heavy-duty use. The front suspension utilizes an independent multi-link setup, providing a comfortable ride and good handling. The rear suspension also employs a multi-link design, contributing to improved stability and load-carrying capacity. Brakes are disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety during emergency braking situations. The truck’s substantial weight and high center of gravity necessitate careful driving, particularly when cornering.
Market Reception & Comparison
The 2013-2018 RAM 2500/3500 with the 6.7L Cummins diesel received generally positive reviews from automotive critics. The engine was praised for its power, durability, and fuel efficiency (relative to its class). The spacious interior and comfortable ride were also noted as strengths. Compared to the gasoline-powered RAM 2500 models, the diesel offered significantly better fuel economy when towing or hauling heavy loads. However, the diesel engine carried a higher initial cost and potentially higher maintenance expenses. Compared to the higher-output Cummins variants, the 350 hp version offered a more balanced combination of performance and affordability.
Legacy
The 6.7L Cummins engine in this RAM 2500/3500 generation has proven to be exceptionally reliable, with many examples exceeding 200,000 miles with proper maintenance. On the used car market, these trucks hold their value well, particularly those in good condition with well-documented service histories. The combination of robust construction, powerful engine, and spacious interior makes them a popular choice for those needing a capable and dependable heavy-duty pickup truck. The 2013-2018 facelifted models are often preferred due to their updated styling and improved interior features.
