Powertrain & Engine Architecture
At the heart of this 3500 variant lies the 6.4-liter HEMI V8 engine. This engine, internally designated as part of the Generation III HEMI family, is a naturally aspirated, pushrod (OHV) design featuring variable valve timing (VCT). The 90-degree V8 configuration provides inherent balance, contributing to smooth operation. The engine utilizes multi-port fuel injection, delivering fuel directly to each cylinder. The 6.4L HEMI produces 405 horsepower at 5,600 rpm and 429 lb-ft of torque at 4,000 rpm. A key feature of this engine is its cylinder deactivation system (MDS), which shuts down four cylinders during light-load cruising to improve fuel economy. The TorqueFlite 8-speed automatic transmission is the sole transmission offering with this engine. This transmission is known for its smooth shifts and durability, and is specifically tuned for heavy-duty applications. It features electronic range selection and tow/haul mode for optimized performance when towing.
Driving Characteristics
The combination of the 6.4-liter HEMI and the 8-speed TorqueFlite transmission delivers a driving experience focused on capability rather than outright speed. While not as quick as lighter-duty trucks or those equipped with smaller engines, the 3500 offers ample power for towing and hauling heavy loads. The TorqueFlite transmission’s gear ratios are optimized for low-end torque, providing strong acceleration from a standstill, even when heavily laden. Compared to the optional diesel engines, this gasoline V8 offers a more responsive feel, with power readily available across the rev range. However, it lacks the diesel’s superior low-end torque and fuel efficiency when towing at highway speeds. The automatic transmission provides convenient operation, but drivers seeking more control may prefer the manual transmission options available with other engines in the 2500/3500 lineup.
Equipment & Trim Levels
The 3500 6.4 HEMI typically comes standard with a well-equipped interior, reflecting its position as a higher-trim level within the 3500 range. Standard features generally include cloth upholstery, air conditioning, a user-friendly infotainment system with a touchscreen display, and basic safety features like ABS and stability control. Higher trim levels, such as Laramie or Limited, add premium features like leather upholstery, heated and ventilated seats, a larger touchscreen, navigation, and advanced safety technologies. Optional extras include a sunroof, upgraded sound system, and various appearance packages.
Chassis & Braking
The RAM 3500 utilizes a robust chassis designed to withstand heavy loads. The front suspension features coil springs and a rigid axle with a transverse stabilizer bar. The rear suspension employs leaf springs, with an optional air suspension system available for improved ride comfort and load leveling. Braking duties are handled by ventilated discs at all four corners, providing ample stopping power. ABS (Anti-lock Braking System) is standard. The steering system is a hydraulic power-assisted recirculating ball setup, offering a direct and responsive feel.
Market Reception & Comparison
The 6.4-liter HEMI V8-powered RAM 3500 has generally been well-received by critics and consumers alike. It’s praised for its strong towing and hauling capabilities, comfortable ride quality, and user-friendly technology. Compared to the diesel-powered RAM 3500 models, the 6.4 HEMI offers a lower initial cost but sacrifices fuel economy and low-end torque. Against competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra 3500, the RAM 3500 is often lauded for its refined interior and comfortable ride. Reliability has been generally good, although some owners have reported minor issues with the cylinder deactivation system.
Legacy
The 6.4-liter HEMI V8 has proven to be a durable and reliable engine in the RAM 2500/3500 lineup. While not as fuel-efficient as diesel alternatives, its simplicity and readily available parts make it a relatively easy engine to maintain. On the used car market, these trucks hold their value well, particularly those in good condition with well-documented maintenance histories. The combination of capability, comfort, and reliability ensures that the 3500 6.4 HEMI remains a popular choice for buyers seeking a heavy-duty pickup truck.
