INTRODUCTION
The 2014-2018 RAM 2500/3500 Crew Cab I facelift, powered by the 6.4-liter Hemi V8 and paired with a six-speed automatic transmission, represented a significant upgrade within the RAM heavy-duty truck lineup. Building upon the foundation of the previous generation, this iteration benefited from a refreshed exterior design, an upgraded interior, and enhanced technology. The “Crew Cab” configuration offered spacious seating for up to six passengers, making it a popular choice for families and work crews alike. This particular variant was positioned as a mid-range offering, bridging the gap between the less powerful 5.7L Hemi V8 and the more expensive and specialized Cummins diesel engines. It was a workhorse designed for demanding tasks, but with a degree of comfort and refinement not typically found in heavier-duty trucks.
Powertrain & Engine Architecture
At the heart of this RAM 2500/3500 variant lies the 6.4-liter (391.59 cubic inches) Hemi V8 engine, internally designated as the ESA engine code. This engine is a naturally aspirated, overhead valve (OHV) design featuring multi-port fuel injection. The 6.4L Hemi is essentially a larger-displacement version of the well-known 5.7L Hemi, sharing many of its core design principles but with increased bore size (103.9 mm / 4.09 in) and stroke (94.6 mm / 3.72 in) to deliver significantly more power and torque. The 10:1 compression ratio contributes to its robust performance. The six-speed automatic transmission, a Torqueflite 68RFE, was specifically engineered to handle the high output of the 6.4L Hemi. This transmission features a wide gear ratio spread, optimizing both towing performance and fuel efficiency. The transmission is electronically controlled, adapting shift points based on driving conditions and throttle input.
Driving Characteristics
The 6.4L Hemi V8 in the RAM 2500/3500 delivers a noticeable surge of power, making it capable of confidently towing substantial loads and navigating challenging terrain. While not as fuel-efficient as the 5.7L Hemi, the 6.4L provides a significant performance advantage. The six-speed automatic transmission is generally smooth and responsive, although some drivers noted that it could occasionally hunt for gears when under heavy load. Compared to the manual transmission options available on other RAM 2500/3500 models, the automatic prioritizes ease of use and convenience over outright driver control. The 4×4 system provides excellent traction in various conditions, and the truck’s robust suspension effectively absorbs bumps and vibrations, even when carrying a heavy payload. The weight-to-power ratio of 7.5 kg/Hp translates to a responsive feel, while the 5.3 kg/Nm weight-to-torque ratio ensures ample pulling power.
Equipment & Trim Levels
The 2500/3500 Crew Cab with the 6.4 Hemi typically came standard with a comprehensive list of features, including air conditioning, power windows and locks, a basic infotainment system with a touchscreen display, and a rearview camera. Higher trim levels, such as the Laramie and Limited, added premium features like leather upholstery, heated and ventilated front seats, a premium sound system, and advanced safety technologies. Optional extras included a navigation system, a sunroof, and various off-road packages. The interior design was generally functional and durable, with a focus on providing a comfortable and practical environment for both work and family use.
Chassis & Braking
The RAM 2500/3500 Crew Cab utilized a robust body-on-frame construction, providing a solid and durable platform for heavy-duty applications. The suspension system featured independent multi-link suspension at both the front and rear, offering a comfortable ride quality and improved handling compared to older designs. Braking duties were handled by disc brakes on all four wheels, providing ample stopping power even when towing heavy loads. An Anti-lock Braking System (ABS) was standard equipment, enhancing safety and control. Hydraulic power steering provided responsive and precise steering feel.
Market Reception & Comparison
The 6.4 Hemi-powered RAM 2500/3500 received generally positive reviews from automotive critics. It was praised for its powerful engine, comfortable ride, and spacious interior. Compared to the 5.7L Hemi, the 6.4L offered a significant performance boost, making it a better choice for those who frequently tow or haul heavy loads. However, it came with a higher price tag and slightly lower fuel economy. Compared to the Cummins diesel options, the 6.4L Hemi was more affordable and simpler to maintain, but it lacked the diesel’s superior torque and fuel efficiency. The 6.4L Hemi found its niche among buyers who wanted a powerful and capable truck without the added cost and complexity of a diesel engine.
Legacy
The 6.4L Hemi V8 has proven to be a relatively reliable powertrain, with many examples still on the road today. While routine maintenance is essential, the engine is generally known for its durability and longevity. The 68RFE automatic transmission has also proven to be robust, although some owners have reported issues with solenoid packs and valve bodies. In the used car market, the 2014-2018 RAM 2500/3500 Crew Cab with the 6.4 Hemi V8 remains a popular choice, offering a compelling combination of power, capability, and comfort. Its continued demand reflects its reputation as a well-rounded and dependable heavy-duty truck.
