The RAM 2500/3500 Crew Cab II (DT), 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 and a 4×4 drivetrain, represents a significant iteration in the heavy-duty pickup truck market. Introduced for the 2019 model year and continuing through 2025, this configuration aimed to balance substantial towing and hauling capability with a degree of everyday usability. It falls within the broader DT generation, a complete redesign of the Ram heavy-duty lineup, focusing on increased strength, refinement, and technology. This particular variant occupied a sweet spot in the lineup, offering a powerful diesel engine without reaching the extreme capabilities (and price point) of the higher-output Cummins options.

Powertrain & Engine Architecture
At the heart of this RAM 2500 is the 6.7-liter Cummins inline-six diesel engine. This engine, designated with various codes depending on the specific year and emissions configuration, is a robust and well-regarded powerplant known for its durability and torque output. The 370 horsepower version utilizes a variable geometry turbocharger (VGT) and a common-rail direct fuel injection system. The common-rail system, operating at extremely high pressures, allows for precise fuel metering and optimized combustion, contributing to both power and efficiency. The engine features four valves per cylinder, enhancing breathing and overall performance. The six-speed automatic transmission, sourced from Aisin, was specifically designed to handle the high torque output of the Cummins engine. It features electronically controlled shifting and a robust internal design for long-term reliability.
Driving Characteristics
The 370 hp/1084 lb-ft configuration of the RAM 2500 delivers a distinctly different driving experience compared to the higher-output Cummins variants or gasoline-powered models. While not as overtly powerful, the 370 hp engine provides ample torque for everyday driving and demanding tasks like towing. The automatic transmission is well-tuned, offering smooth shifts and responsive acceleration. The gear ratios are optimized for towing, providing strong pulling power in lower gears. Compared to the manual transmission options, the automatic prioritizes ease of use and convenience, making it a popular choice for drivers who frequently tow or haul heavy loads. The weight of the truck is noticeable, but the strong suspension and capable brakes provide a confident and controlled driving experience.
Equipment & Trim Levels
The 2500 6.7 Cummins Automatic was available across several trim levels, including Tradesman, Big Horn/Laramie, and Limited. The base Tradesman trim offered a functional and durable interior with vinyl upholstery and basic amenities. Higher trims like the Big Horn/Laramie added features such as cloth or leather upholstery, upgraded infotainment systems, and more refined interior finishes. The Limited trim represented the pinnacle of luxury, offering premium leather, wood trim, and a host of advanced technology features. Standard equipment generally included air conditioning, power windows and locks, and a basic audio system. Optional extras included a premium sound system, navigation, a sunroof, and various driver-assistance technologies.
Chassis & Braking
The RAM 2500/3500 Crew Cab II (DT) utilizes a fully boxed frame constructed from high-strength steel, providing a solid foundation for the truck. The front suspension features an independent multi-link design with coil springs, offering a comfortable ride and good handling. The rear suspension also employs a multi-link setup with coil springs, providing improved ride quality and stability compared to traditional leaf spring designs. Braking duties are handled by disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations.
Market Reception & Comparison
The RAM 2500/3500 with the 370 hp Cummins engine and automatic transmission was generally well-received by critics and consumers. It was praised for its strong towing capability, comfortable ride, and refined interior. Compared to the higher-output Cummins variants, this configuration offered a more affordable price point and slightly better fuel economy. However, it lacked the sheer power of the more powerful engines. Compared to competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM 2500 was often lauded for its superior ride quality and interior refinement. Fuel economy, while respectable for a heavy-duty truck, typically ranged from 17-20 mpg in combined driving conditions.
Legacy
The 6.7-liter Cummins engine in this configuration has proven to be remarkably durable and reliable. With proper maintenance, these engines can easily exceed 200,000 miles. On the used car market, these RAM 2500/3500 trucks hold their value well, particularly those that have been well-maintained and have a documented service history. The combination of power, capability, and refinement has made this variant a popular choice among truck enthusiasts and those who require a heavy-duty vehicle for work or recreation. The DT generation RAM trucks, including this 2500 variant, are considered a significant step forward in the heavy-duty truck segment, setting a new standard for comfort, technology, and capability.
