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 (formerly Chrysler Group LLC). This variant, equipped with the 5.7-liter Hemi V8 engine and a six-speed automatic transmission, occupied a sweet spot in the RAM 1500 lineup, balancing capability with relative affordability. It catered to buyers needing a robust work truck or a comfortable daily driver without the added expense of higher trim levels or the more specialized features of the Crew Cab models. The “DS” designation refers to the fourth generation of the RAM 1500, receiving a substantial refresh in 2013 that included updated styling, improved interior materials, and enhanced technology.

Powertrain & Engine Architecture
At the heart of the RAM 1500 Regular Cab DS is the 5.7-liter Hemi V8 engine, designated as the EZH code. This engine is a member of Chrysler’s third-generation Hemi family, known for its robust construction and strong low-end torque. The engine features a cast iron block, aluminum cylinder heads, and a single overhead valve (OHV) valvetrain. The 5.7L Hemi utilizes a multi-point fuel injection system, delivering fuel directly to each cylinder. A key feature of this engine is the Multi-Displacement System (MDS), which allows it to seamlessly switch between eight and four cylinders under light load conditions, improving fuel economy. The six-speed automatic transmission (68RFE) was specifically chosen for its durability and ability to handle the engine’s substantial torque output. This transmission features electronically controlled shifting and tow/haul mode for optimized performance when towing.
Driving Characteristics
The combination of the 395-horsepower Hemi V8 and the six-speed automatic transmission provides a compelling driving experience. While not as quick as some of the lighter, more performance-oriented trucks, the RAM 1500 DS offers ample power for everyday driving and hauling. The automatic transmission is tuned for smooth shifts and responsive acceleration. The gear ratios are optimized for towing and hauling, providing strong low-end torque. Compared to the 3.6L Pentastar V6 option, the 5.7L Hemi delivers significantly more power and torque, making it ideal for those who frequently tow or carry heavy loads. However, the V6 offered better fuel economy. Compared to manual transmission equipped 5.7L models, the automatic provides convenience and ease of use, though some drivers may prefer the greater control offered by a manual gearbox.
Equipment & Trim Levels
The RAM 1500 Regular Cab DS with the 5.7 Hemi V8 typically came standard with features such as air conditioning, power windows and locks, a basic audio system, and steel wheels. Higher trim levels, such as the SLT and Laramie, added features like cloth or leather upholstery, upgraded audio systems, alloy wheels, and additional convenience features. Optional extras included a navigation system, a rearview camera, and various towing packages. The interior design was functional and durable, with a focus on providing a comfortable work environment. The Regular Cab configuration offered seating for two to three passengers, making it suitable for individual workers or small crews.
Chassis & Braking
The RAM 1500 DS features a robust chassis designed to handle heavy loads and provide a comfortable ride. The front suspension utilizes a double wishbone design, while the rear suspension employs an independent multi-link setup. This suspension configuration provides a good balance of ride quality and handling. Braking duties are handled by ventilated discs at the front and discs at the rear, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations.
Market Reception & Comparison
The RAM 1500 Regular Cab with the 5.7 Hemi V8 was generally well-received by critics and consumers alike. It was praised for its powerful engine, comfortable ride, and spacious interior. However, some critics noted that the fuel economy was not as good as some of its competitors. Compared to the Ford F-150 and Chevrolet Silverado, the RAM 1500 offered a unique combination of features and capabilities. The RAM’s coil-spring rear suspension provided a smoother ride than the leaf-spring setups found in some competitors. Reliability was generally considered good, although some owners reported issues with the MDS system.
Legacy
The 5.7 Hemi V8-powered RAM 1500 Regular Cab (DS) remains a popular choice in the used truck market. Its robust powertrain and durable construction make it a reliable and capable work truck. The engine is known for its longevity, and with proper maintenance, it can provide many years of service. While newer RAM 1500 models offer more advanced technology and features, the DS generation represents a solid value for buyers seeking a dependable and affordable full-size pickup truck. The 68RFE transmission, while sometimes criticized for early issues, proved to be a durable unit when properly maintained, and parts availability remains good.
