Introduction
The 2019-2025 RAM 2500/3500 Regular Cab II (DT) featuring the 6.4-liter Hemi V8 engine and a six-speed automatic transmission occupied a crucial position in the Ram Heavy Duty lineup. Built on the DT platform, which debuted in 2019, this configuration offered a compelling blend of power, capability, and relative affordability. The Regular Cab configuration, with its two or three-passenger seating, catered to buyers prioritizing work-truck functionality and a more compact footprint compared to the Crew Cab and Mega Cab models. This variant was particularly popular with commercial users, farmers, and individuals needing a robust truck for demanding tasks.
Powertrain & Engine Architecture
At the heart of this RAM 2500/3500 is the 6.4-liter (391.59 cubic inch) Hemi V8 engine, internally designated as the 6.4L HEMI. This engine is a naturally aspirated, overhead valve (OHV) design, known for its robust construction and relatively simple maintenance requirements. It utilizes multi-port fuel injection to deliver fuel directly into the intake ports, and features a cast iron block with aluminum cylinder heads. The engine produces 410 horsepower at 5600 rpm and 429 lb-ft of torque at 4000 rpm. The 6.4L Hemi is known for its characteristic V8 rumble and strong low-end torque, making it well-suited for towing and hauling. Paired with this engine is an eight-speed automatic transmission (8HP70), providing a wide gear ratio spread for optimized performance and fuel efficiency. This transmission is electronically controlled and features a tow/haul mode that adjusts shift points for improved towing stability and control.
Driving Characteristics
The 6.4 Hemi V8 and eight-speed automatic combination delivers a confident and capable driving experience. While not as fuel-efficient as the smaller engine options, or as powerful as the Cummins diesel, it provides ample power for most tasks. The eight-speed transmission helps keep the engine in its optimal power band, resulting in brisk acceleration and responsive performance. Compared to the manual transmission equipped 6.4L Hemi, the automatic offers smoother operation and reduced driver fatigue, particularly in stop-and-go traffic. The 4×4 system provides excellent traction in various conditions, making it suitable for both on-road and off-road use. The Regular Cab configuration, being lighter than the larger cab variants, contributes to slightly improved handling and maneuverability.
Equipment & Trim Levels
The 2500/3500 Regular Cab with the 6.4 Hemi V8 was typically offered in several trim levels, including Tradesman, Big Horn/Laramie, and Power Wagon. The base Tradesman trim focused on functionality, with standard features like air conditioning, a basic infotainment system, and vinyl upholstery. Higher trims like the Big Horn/Laramie added more comfort and convenience features, such as cloth or leather upholstery, upgraded infotainment systems with larger touchscreens, and additional chrome exterior trim. Optional extras included a premium sound system, navigation, parking sensors, and various towing packages. The Power Wagon trim, specifically geared towards off-road enthusiasts, included features like a locking rear differential, electronic disconnecting sway bar, and more aggressive tires.
Chassis & Braking
The RAM 2500/3500 utilizes a robust fully boxed frame construction, providing a solid foundation for heavy-duty use. The front suspension features an independent multi-link setup with coil springs, while the rear suspension also employs a multi-link design with leaf springs. This configuration provides a comfortable ride while maintaining excellent load-carrying capacity. Braking duties are handled by four-wheel disc brakes with ABS (Anti-lock Braking System). The braking system is designed to provide strong and reliable stopping power, even when towing heavy loads. The rear axle ratios varied depending on the specific configuration and towing package selected, influencing both fuel economy and towing capacity.
Market Reception & Comparison
The 6.4 Hemi V8-powered RAM 2500/3500 received generally positive reviews from automotive critics. It was praised for its strong performance, comfortable ride, and well-appointed interior. Compared to the base V6 engine, the 6.4 Hemi offered a significant increase in power and towing capacity. However, it was less fuel-efficient than the V6 and the Cummins diesel options. Compared to the Cummins diesel, the 6.4 Hemi was more affordable and simpler to maintain, but lacked the diesel’s superior torque and fuel economy. The 6.4 Hemi found its niche among buyers who needed a powerful and capable truck but didn’t require the extreme towing capacity or fuel efficiency of a diesel.
Legacy
The 6.4 Hemi V8 engine has proven to be a reliable and durable powertrain in the RAM 2500/3500. While not without its minor issues (such as potential oil consumption in some early model years), it generally enjoys a good reputation for longevity. In the used car market, these trucks hold their value reasonably well, particularly those in good condition with well-documented maintenance histories. The combination of power, capability, and relative affordability makes the 2019-2025 RAM 2500/3500 Regular Cab with the 6.4 Hemi V8 a popular choice for buyers seeking a robust and dependable heavy-duty pickup truck.
