Technical Specifications

INTRODUCTION

The 2019-2025 RAM 2500/3500 Crew Cab Long II (DT) featuring the 6.7-liter Cummins diesel and automatic transmission is a heavy-duty pickup truck designed for demanding tasks. Built on the DT platform, this generation represented a significant leap forward in refinement and capability for the Ram Heavy Duty line. The “Crew Cab Long” configuration offered a spacious interior and a long bed, making it suitable for both work and family use. This specific powertrain combination aimed to provide a balance between the immense torque of the Cummins engine and the convenience of an automatic transmission, appealing to a broad range of buyers in the North American market.

Powertrain & Engine Architecture

At the heart of this variant lies the 6.7-liter Cummins inline-six diesel engine. This engine, designated with various codes throughout the DT generation, 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 to optimize performance and efficiency. The common-rail system, operating at extremely high pressures, allows for precise fuel metering and improved combustion. The engine features four valves per cylinder and a cast iron block, contributing to its longevity. The automatic transmission paired with this engine is typically a six-speed unit, specifically designed to handle the high torque output of the Cummins. This transmission features electronically controlled shifts and a heavy-duty torque converter.

Driving Characteristics

The 6.7L Cummins with the automatic transmission delivers a driving experience focused on effortless towing and hauling. While not as quick as gasoline-powered counterparts or higher-output Cummins variants, the 370 hp version provides ample power for most tasks. The automatic transmission shifts smoothly, and the torque converter multiplies engine torque, providing strong low-end grunt. The gear ratios are optimized for towing, with lower gears providing substantial pulling power. Compared to manual transmission versions, the automatic offers greater convenience, especially in stop-and-go traffic. However, some drivers may prefer the more direct feel and control of a manual gearbox. Compared to the higher-output Cummins variants (400 hp or more), this version offers a slightly more relaxed driving experience, with less aggressive throttle response.

Equipment & Trim Levels

The 2500/3500 Crew Cab Long II (DT) 6.7 Cummins Automatic was available in a variety of trim levels, including Tradesman, Big Horn/Laramie, and Limited. The base Tradesman trim offered a functional interior with vinyl upholstery and basic features. Higher trims, like the Laramie, added leather upholstery, heated and ventilated seats, a premium sound system, and more advanced infotainment features. Standard equipment typically included air conditioning, power windows and locks, and a rearview camera. Optional extras included a sunroof, navigation system, and various driver-assistance technologies. The Long bed configuration provided ample cargo space, and the Crew Cab offered a spacious rear seat for passengers.

Chassis & Braking

The RAM 2500/3500 utilizes a robust chassis designed to withstand heavy loads. The suspension system consists of independent multi-link suspension at both the front and rear, providing a comfortable ride even when the truck is loaded. The braking system features disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard. The rear axle ratio varies depending on the specific configuration, but is typically geared for towing and hauling. The steering system is a hydraulic rack-and-pinion setup, providing precise steering control.

Market Reception & Comparison

The RAM 2500/3500 with the 6.7L Cummins and automatic transmission was generally well-received by critics and consumers. It was praised for its comfortable ride, spacious interior, and powerful engine. Fuel economy, while not a primary concern for heavy-duty truck buyers, was considered reasonable for a vehicle of this size and capability. Compared to competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the Ram offered a more refined interior and a smoother ride. The Cummins engine was consistently ranked among the most reliable and durable diesel engines in the industry. However, some critics noted that the automatic transmission could sometimes feel sluggish when downshifting.

Legacy
