The RAM 1500 Regular Cab (DS), specifically the facelifted version produced from 2013 to 2018, represents a significant iteration of the full-size pickup truck offered by Stellantis (then Chrysler Group LLC) in the North American market. This variant, equipped with the 5.7-liter Hemi V8 engine producing 395 horsepower and paired with a six-speed automatic transmission, and a 4×4 drivetrain, occupied a sweet spot in the lineup, balancing capability with relative affordability. It catered to buyers needing a robust work truck or a capable daily driver without the added expense of higher trim levels or more specialized configurations. The “DS” designation refers to the second generation of the redesigned 1500, receiving a substantial facelift in 2013 that included revised styling, upgraded interior materials, and enhanced technology.

Powertrain & Engine Architecture
The heart of this RAM 1500 variant is the 5.7-liter Hemi V8 engine, internally designated as the EZH. This engine is a member of Chrysler’s third-generation Hemi family, known for its robust construction and relatively simple design. It features a cast iron block, aluminum cylinder heads, and an overhead valve (OHV) valvetrain. The engine utilizes a multi-port fuel injection system, delivering fuel directly to each cylinder. The 5.7L Hemi is notable for its Variable Valve Timing (VVT) technology, which optimizes engine performance and fuel efficiency by adjusting valve timing based on engine load and speed. The six-speed automatic transmission (typically the 68RFE) was specifically chosen for its durability and ability to handle the engine’s substantial torque output. This transmission features electronically controlled shifting and a tow/haul mode for improved performance when towing heavy loads. The 4×4 system employs an electronically controlled transfer case, allowing the driver to switch between two-wheel drive, four-wheel drive high, and four-wheel drive low.
Driving Characteristics
The 395 horsepower and 404 lb-ft of torque delivered by the 5.7L Hemi, coupled with the six-speed automatic, provided a solid, if not exhilarating, driving experience. Acceleration was adequate for everyday driving and hauling moderate loads. The automatic transmission was tuned for smooth shifts and generally responsive performance. Compared to the available 3.6L V6, the Hemi offered significantly more power and towing capacity. However, it lacked the fuel efficiency of the smaller engine. Against higher-output Hemi variants (particularly those with performance-oriented tuning), this version felt less aggressive, but it provided a more balanced combination of power and economy. The automatic transmission’s gear ratios were optimized for towing and hauling, resulting in a slightly lower final drive ratio compared to manual transmission equipped models. This meant quicker acceleration with a load, but potentially slightly higher engine speeds at highway cruising.
Equipment & Trim Levels
The 2013-2018 RAM 1500 Regular Cab with the 5.7 Hemi and 4×4 typically came standard with features like air conditioning, power windows and locks, a basic audio system, and a tilt steering wheel. The interior generally featured durable cloth upholstery. Optional extras included upgraded audio systems (often with touchscreen displays), power-adjustable seats, remote keyless entry, and various chrome exterior trim packages. This configuration often served as a base for work trucks, so many examples were equipped with minimal options. Higher trim levels, such as the SLT or Laramie, added more luxurious features like leather upholstery, heated seats, and advanced safety technologies.
Chassis & Braking
The RAM 1500’s chassis was a body-on-frame construction, providing a robust platform for hauling and towing. The front suspension utilized a double wishbone design, while the rear suspension employed an independent multi-link setup. This combination aimed to provide a comfortable ride while maintaining good handling characteristics. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock brakes (ABS) were standard equipment. Due to the truck’s weight and intended use, the braking system was designed for durability and stopping power under heavy loads rather than sporty performance. Stabilizer bars were included to reduce body roll during cornering.
Market Reception & Comparison
The RAM 1500 with the 5.7 Hemi and 4×4 was generally well-received by critics and consumers alike. It was praised for its strong engine, comfortable ride, and capable towing capacity. Fuel economy, however, was a common criticism, as the Hemi V8 was not particularly fuel-efficient compared to some of its competitors. Compared to the Ford F-150 and Chevrolet Silverado, the RAM 1500 offered a unique combination of features and styling. The RAM’s coil spring rear suspension, in particular, was often cited as providing a smoother ride than the leaf spring setups found in some competitors. Reliability was generally considered good, although some owners reported issues with the electronic stability control system.
Legacy
The 5.7L Hemi V8 paired with the 68RFE automatic transmission has proven to be a durable and reliable powertrain combination. These engines are known to withstand high mileage with proper maintenance. In the used car market, these RAM 1500s remain popular choices for buyers seeking a capable and affordable full-size pickup truck. While newer RAM 1500 models offer more advanced technology and improved fuel efficiency, the 2013-2018 generation continues to represent a solid value proposition, particularly for those prioritizing capability and simplicity. Parts availability is excellent, and the engine’s relatively straightforward design makes it relatively easy to maintain and repair.
