The RAM 2500/3500 Mega Cab I (facelift 2013) represents a significant iteration of the heavy-duty pickup truck lineage from Stellantis (formerly Chrysler Group LLC). Produced from 2013 to 2018, this generation built upon the foundation laid by its predecessors, offering increased capability, refinement, and technology. The 2500 model, specifically equipped with the 5.7-liter Hemi V8 engine and a six-speed automatic transmission, occupied a crucial position in the lineup, serving as a popular choice for buyers seeking a balance between work-ready performance and everyday usability. This configuration was positioned as a step up from the base engine options, offering considerably more power and torque for towing and hauling, while remaining more accessible than the more powerful Cummins diesel variants.

Powertrain & Engine Architecture
At the heart of this RAM 2500 variant lies the 5.7-liter Hemi V8 engine, designated with the code EZC. 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 with aluminum cylinder heads, and utilizes a multi-point fuel injection system to deliver fuel to the cylinders. The engine’s valvetrain employs two valves per cylinder, operated by hydraulic lifters and a single overhead camshaft. The 5.7L Hemi is known for its characteristic rumble and responsive throttle. Paired with this engine is a six-speed automatic transmission (68RFE), a heavy-duty unit designed to handle the substantial torque output of the V8. This transmission features electronically controlled shifting and a tow/haul mode to optimize performance when towing trailers or carrying heavy loads. The 68RFE transmission is known for its durability and smooth operation.
Driving Characteristics
The 5.7 Hemi V8, when coupled with the six-speed automatic, delivers a driving experience that prioritizes usability and capability over outright speed. While not as quick as some of the lighter-duty pickups or those equipped with the Cummins diesel, the RAM 2500 provides ample power for everyday driving and demanding tasks. The automatic transmission’s gear ratios are tuned to provide strong low-end torque for towing and hauling, while still offering comfortable cruising at highway speeds. Compared to manual transmission versions, the automatic offers a more relaxed driving experience, particularly in stop-and-go traffic. However, some drivers may prefer the greater control offered by a manual gearbox. The 4×4 system provides excellent traction in a variety of conditions, making this truck capable both on and off-road.
Equipment & Trim Levels
The 2500 with the 5.7 Hemi and automatic transmission was available in a range of trim levels, including STX, SLT, Laramie, and Limited. Standard features typically included air conditioning, power windows and locks, a basic audio system, and a tilt steering wheel. Higher trim levels added features such as leather upholstery, heated and ventilated seats, a premium audio system, navigation, and a rearview camera. The Mega Cab configuration offered a significantly larger rear seat area than the standard cab, making it ideal for families or passengers who require extra space. Optional extras included a sunroof, upgraded wheels, and various towing packages.
Chassis & Braking
The RAM 2500/3500 chassis is a body-on-frame design, providing a robust and durable platform for heavy-duty use. The front suspension utilizes an independent multi-link setup, while the rear suspension also employs a multi-link design with coil springs. This suspension configuration provides a comfortable ride, even when the truck is loaded. Braking duties are handled by disc brakes on all four wheels, with ABS (Anti-lock Braking System) as standard equipment. The braking system is designed to provide strong and reliable stopping power, even when towing heavy loads.
Market Reception & Comparison
The RAM 2500/3500 with the 5.7 Hemi V8 and automatic transmission was generally well-received by critics and consumers alike. It was praised for its comfortable ride, spacious interior, and strong towing capacity. Fuel economy, however, was a common criticism, as the 5.7 Hemi is not known for its efficiency. Compared to the Cummins diesel variants, the 5.7 Hemi offered a lower price point and simpler maintenance requirements, but it lacked the diesel’s superior torque and fuel economy. Compared to competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM 2500 was often seen as offering a more refined and comfortable driving experience.
Legacy
The 5.7 Hemi V8 and 68RFE automatic transmission combination has proven to be a reliable and durable powertrain. While not without its quirks, these components have generally held up well over time, and are relatively easy to maintain. In the used car market, these RAM 2500/3500 trucks remain popular choices for buyers seeking a capable and affordable heavy-duty pickup. The 2013-2018 facelifted models are particularly desirable, as they offer a number of improvements over earlier generations, including a more modern interior and updated technology.
