The RAM 2500/3500 Crew Cab Long II (DT) with the 6.4 Hemi V8 engine and four-wheel drive automatic transmission represents a significant offering in the heavy-duty pickup truck segment. Produced from 2019 through 2025, this configuration aimed to balance substantial capability with a degree of refinement and everyday usability. Positioned as a mid-to-upper tier trim within the 2500/3500 lineup, it slotted above the base engine options (typically a Cummins diesel or smaller gasoline V8) but below the highest-output Cummins diesel variants. This model catered to buyers needing serious towing and hauling capacity, but who also desired the responsiveness and sound of a gasoline V8.

Powertrain & Engine Architecture
At the heart of this RAM variant lies the 6.4-liter (392 cubic inch) HEMI V8 engine, internally designated as the 6.4L Hemi. This engine is a member of Chrysler’s Generation III HEMI family, featuring overhead valve (OHV) valvetrain, and multi-port fuel injection. The engine produces 410 horsepower at 5,600 rpm and 429 lb-ft of torque at 4,000 rpm. The engine’s architecture emphasizes low-end torque, making it well-suited for towing and hauling. The 6.4L Hemi utilizes a cast iron block with aluminum cylinder heads. The engine is paired with a robust eight-speed automatic transmission (typically the ZF 8HP70), known for its smooth shifting and wide gear ratio spread. This transmission is crucial for managing the engine’s power and optimizing fuel efficiency, especially when towing heavy loads.
Driving Characteristics
The 6.4 Hemi V8 in the RAM 2500/3500 delivers a distinctly different driving experience compared to the diesel options. While lacking the sheer pulling power of the Cummins diesel, the 6.4L provides quicker acceleration and a more responsive feel. The eight-speed automatic transmission helps keep the engine in its optimal power band, providing adequate power for most towing and hauling scenarios. The gear ratios are tuned for both on-road comfort and off-road capability. Compared to the manual transmission options (available on some trims), the automatic offers greater convenience, particularly in stop-and-go traffic or when navigating challenging terrain. However, some drivers may prefer the greater control offered by a manual gearbox. The 4×4 system provides excellent traction in various conditions, making it a capable off-road vehicle.
Equipment & Trim Levels
The 6.4 Hemi-equipped RAM 2500/3500 typically came standard with a well-appointed interior, including cloth upholstery, air conditioning, a touchscreen infotainment system, and a rearview camera. Higher trim levels, such as the Laramie, Longhorn, and Limited, added features like leather upholstery, heated and ventilated seats, a premium sound system, and advanced safety technologies. Optional extras included a sunroof, navigation system, and various driver-assistance features. The Crew Cab configuration provided ample space for passengers, making it a comfortable choice for families or work crews.
Chassis & Braking
The RAM 2500/3500 utilizes a heavy-duty chassis designed to withstand the stresses of towing and hauling. The suspension system features independent multi-link suspension at both the front and rear, providing a relatively comfortable ride for a heavy-duty truck. Braking duties are handled by disc brakes on all four wheels, with ABS (Anti-lock Braking System) as standard equipment. The braking system is designed to provide adequate stopping power, even when towing heavy loads. The rear axle ratios varied depending on the specific configuration and intended use, with options available to optimize either fuel economy or towing capacity.
Market Reception & Comparison
The 6.4 Hemi-powered RAM 2500/3500 received generally positive reviews from automotive critics. It was praised for its strong performance, comfortable ride, and well-equipped interior. However, some critics noted that its fuel economy was lower than that of the diesel options. Compared to the Cummins diesel variants, the 6.4 Hemi offered a lower initial cost but higher long-term operating costs due to fuel consumption. The 6.4 Hemi was often seen as a good choice for buyers who prioritized performance and responsiveness over maximum towing capacity and fuel efficiency.
Legacy
The 6.4 Hemi V8 has proven to be a relatively reliable powertrain, with few widespread mechanical issues reported. The eight-speed automatic transmission has also demonstrated good durability. In the used car market, these RAM 2500/3500 models hold their value reasonably well, particularly those in good condition with low mileage. The combination of power, capability, and comfort has made this variant a popular choice among truck enthusiasts and those needing a versatile and dependable heavy-duty pickup.
