Powertrain & Engine Architecture
The heart of this RAM variant is the 6.7-liter Cummins inline-six diesel engine. This engine, designated with various codes throughout its production run, 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 high-pressure common rail fuel injection system to optimize performance and efficiency. The common rail system allows for multiple injection events per combustion cycle, improving fuel atomization and reducing emissions. The engine features a cast iron block and head, contributing to its longevity. The automatic transmission paired with this engine is typically a six-speed unit, specifically the 68RFE. This transmission is a heavy-duty design capable of handling the substantial torque produced by the Cummins engine. It features electronic control and multiple shift schedules to balance performance and fuel economy.
Driving Characteristics
The 370 hp/1084 lb-ft configuration delivers a strong and usable powerband, particularly well-suited for towing and hauling. While not as quick accelerating as the higher-output Cummins variants, the 370 hp version provides ample power for most tasks. The automatic transmission generally shifts smoothly, although some drivers may find it hunts for gears under heavy load or in hilly terrain. The 68RFE transmission’s gear ratios are optimized for towing, with lower gears providing significant pulling power. Compared to manual transmission equipped models, the automatic offers convenience, especially in stop-and-go traffic, but may result in a slight reduction in fuel economy. The substantial weight of the truck is always noticeable, but the Cummins engine provides the necessary grunt to overcome this.
Equipment & Trim Levels
The 2500/3500 Crew Cab II (DT) with the 6.7L Cummins and automatic transmission was available in various trim levels, including Tradesman, Big Horn/Laramie, and Limited. The Tradesman trim served as the base model, offering essential features like air conditioning, a basic infotainment system, and vinyl upholstery. Higher trims like the Big Horn/Laramie added features such as cloth or leather upholstery, upgraded infotainment systems with larger touchscreens, power-adjustable seats, and chrome exterior accents. The Limited trim represented the most luxurious option, including premium leather, wood trim, and advanced safety features. Optional extras included a sunroof, navigation system, premium sound system, and various driver-assistance technologies.
Chassis & Braking
The RAM 2500/3500 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, while the rear suspension employs a multi-link setup with leaf springs. This configuration balances ride comfort with load-carrying capacity. Braking duties are handled by four-wheel disc brakes with ABS. The braking system is sized appropriately for the truck’s weight and towing capacity. Depending on the trim level and axle ratio, the rear axle could be equipped with a limited-slip differential to improve traction.
Market Reception & Comparison
The 370 hp Cummins-powered RAM 2500/3500 received generally positive reviews. Critics praised its strong towing capability, comfortable ride, and refined interior (particularly in higher trim levels). Fuel economy, while respectable for a heavy-duty truck, was not a standout feature. Compared to the higher-output Cummins variants (e.g., the 400 hp version), the 370 hp model offered a more affordable entry point into the heavy-duty truck segment. Compared to competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM 2500/3500 was often lauded for its ride quality and interior refinement.
Legacy
The 6.7-liter Cummins engine has established a reputation for exceptional reliability and longevity. With proper maintenance, these engines can easily exceed 200,000 or even 300,000 miles. The 68RFE automatic transmission is also generally considered durable, although some owners have reported issues with the torque converter or valve body. On the used car market, these trucks hold their value relatively well, particularly those in good condition with well-documented maintenance histories. The 2019-2025 RAM 2500/3500 Crew Cab II (DT) with the 6.7L Cummins and automatic transmission remains a popular choice for buyers seeking a capable and reliable heavy-duty pickup truck.
