2013-2018 RAM 25003500 Crew Cab I (facelift ) 2500 6.7 Cummins TD (370 Hp) Automatic

The RAM 2500/3500 Crew Cab I (facelifted in 2013) represents a significant iteration in the heavy-duty pickup truck lineage from Stellantis (formerly Chrysler Group LLC). Specifically, the 2500 model equipped with the 6.7-liter Cummins turbocharged diesel engine producing 370 horsepower and paired with a six-speed automatic transmission, was a mainstay of the lineup from 2013 through 2018. This configuration aimed to balance substantial towing and hauling capability with a degree of everyday usability, positioning itself as a workhorse for both commercial and personal applications. It built upon the foundation of the previous generation, offering improved refinement, technology, and a more robust powertrain.

Technical Specifications

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 represents a mature design, having undergone continuous refinement since its introduction. It features a cast iron block and head, known for their durability, and utilizes a common-rail direct injection system to deliver fuel at extremely high pressures for optimized combustion. The turbocharger, coupled with an intercooler, significantly boosts power output and improves efficiency. The overhead valve (OHV) configuration, while seemingly dated, contributes to the engine’s robustness and low-end torque characteristics. The six-speed automatic transmission, sourced from Aisin, was chosen for its ability to handle the engine’s substantial torque output and provide smooth shifting. This transmission featured electronically controlled shifting and a tow/haul mode optimized for heavy loads.

Driving Characteristics

The 370 horsepower and 1084 lb-ft of torque delivered by this powertrain combination resulted in a truck capable of impressive feats of towing and hauling. While not as quick as gasoline-powered counterparts, the Cummins diesel provided a broad, flat torque curve, making it exceptionally capable in demanding situations. The automatic transmission, while smooth, wasn’t geared for outright acceleration; instead, it prioritized maintaining engine RPMs within the optimal torque band. Compared to the higher-output Cummins variants (like the 420 hp version), this 370 hp configuration offered a more relaxed driving experience, with less engine noise and vibration. Manual transmission options were available, offering more driver control but sacrificing some convenience.

Equipment & Trim Levels

The 2500/3500 Crew Cab 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 features like leather upholstery, heated front seats, a premium audio system, and chrome exterior accents. The Limited trim represented the pinnacle of luxury, with features like premium leather, wood trim, navigation, and advanced safety technologies. Optional extras included a sunroof, upgraded wheels, and various towing packages.

Chassis & Braking

The RAM 2500/3500 chassis was built around a robust fully boxed frame, designed to withstand the stresses of heavy-duty use. The suspension system utilized a multi-link configuration at both the front and rear, providing a comfortable ride quality despite the truck’s substantial weight. Disc brakes were standard on all four wheels, providing ample stopping power. The rear axle ratios varied depending on the specific configuration and intended use, with lower ratios (numerically higher) providing better towing capability and higher ratios offering improved fuel economy. Stabilizer bars were included to reduce body roll during cornering.

Market Reception & Comparison

The 2500/3500 with the 6.7L Cummins and automatic transmission was generally well-received by critics and consumers alike. It was praised for its powerful engine, comfortable ride, and capable towing capacity. Fuel economy, while not a primary concern for heavy-duty truck buyers, was considered reasonable for its class. Compared to the gasoline-powered RAM 2500/3500 models, the Cummins diesel offered significantly more torque and better fuel economy when towing heavy loads. However, the diesel engine carried a higher initial cost and potentially higher maintenance expenses. Compared to competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM 2500/3500 was often seen as offering a more refined interior and a more comfortable ride.

Legacy

The 6.7L Cummins engine, in all its iterations, has earned a reputation for exceptional durability and longevity. The powertrain combination found in the 2013-2018 RAM 2500/3500 continues to be highly regarded in the used truck market. Properly maintained examples can easily exceed 200,000 miles, and many have surpassed 300,000 miles. The Aisin transmission is also known for its reliability. While diesel engines generally require more diligent maintenance than gasoline engines, the Cummins’ robust design and readily available parts supply contribute to its long-term dependability. These trucks remain a popular choice for those seeking a capable and reliable heavy-duty pickup.
