The RAM 2500/3500 Crew Cab I (facelift 2013), specifically the 3500 model equipped with the 6.7 HO Cummins turbocharged diesel engine and automatic transmission, represents a significant iteration in the heavy-duty truck segment. Produced from 2013 to 2018, this variant aimed to deliver a balance of robust towing capacity, respectable horsepower, and a degree of daily drivability. It occupied a position within the RAM lineup as a high-output option, bridging the gap between the standard Cummins and the even more powerful, though less common, high-output variants. This model was primarily targeted at the North American market, where heavy-duty trucks are widely used for both commercial and personal applications, including hauling, construction, and recreational activities.

Powertrain & Engine Architecture
At the heart of this RAM 3500 variant lies the 6.7-liter Cummins inline-six diesel engine, designated as the HO (High Output) version. This engine, identified by the ETK code, is a robust and durable powerplant known for its longevity and torque production. The 6.7L Cummins utilizes a cast iron block and head, contributing to its inherent strength. The HO version differentiates itself from the standard output Cummins through a larger turbocharger and revised fuel injection settings, resulting in the increased 385 horsepower and substantial 1152 Nm (849.67 lb-ft) of torque. Fuel is delivered via a high-pressure common rail diesel injection system, optimizing combustion efficiency and reducing emissions. The engine employs an overhead valve (OHV) valvetrain, a design choice prioritizing simplicity and reliability over higher-revving performance. The automatic transmission is a six-speed unit sourced from Aisin, known for its durability and smooth shifting characteristics. This transmission was specifically chosen to handle the high torque output of the Cummins engine.
Driving Characteristics
The 385 hp/1152 Nm combination delivers a commanding driving experience. While not as overtly quick as lighter-duty trucks, the RAM 3500 with this powertrain excels in situations demanding substantial pulling power. The Aisin transmission is well-matched to the engine’s torque curve, providing relatively quick acceleration from a standstill and confident passing power when fully loaded. The gear ratios are optimized for towing, meaning that the truck will readily downshift when encountering inclines or when a heavy load is attached. Compared to the standard output Cummins, the HO version offers noticeably more power, particularly at higher engine speeds. However, the difference in everyday driving is less pronounced than when towing or hauling heavy payloads. Compared to gasoline-powered RAM 2500/3500 models, the diesel offers significantly more low-end torque, making it ideal for work applications.
Equipment & Trim Levels
The 3500 Crew Cab with the 6.7 HO Cummins and automatic transmission was typically offered in higher trim levels, such as SLT, Laramie, and Limited. Standard features generally included air conditioning, power windows and locks, a basic audio system, and cloth upholstery. Higher trims added features like leather upholstery, heated and ventilated seats, a premium sound system, navigation, and various driver-assistance technologies. Optional extras included a sunroof, upgraded wheels, and various appearance packages. The Crew Cab configuration provided ample space for passengers, making it a popular choice for families and work crews alike.
Chassis & Braking
The RAM 3500 chassis is built around a heavy-duty frame designed to withstand the stresses of heavy towing and hauling. The front suspension utilizes an independent multi-link setup, providing a relatively comfortable ride for a heavy-duty truck. The rear suspension employs a traditional leaf spring design, optimized for load-carrying capacity. Braking duties are handled by disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard equipment. Due to the substantial weight of the vehicle, particularly when loaded, the braking system is crucial for maintaining control and ensuring safe stopping distances.
Market Reception & Comparison
The RAM 3500 with the 6.7 HO Cummins and automatic transmission was generally well-received by critics and consumers alike. It was praised for its robust towing capacity, comfortable ride (for a heavy-duty truck), and the legendary durability of the Cummins engine. Fuel economy, while not a primary concern for truck buyers, was respectable for a vehicle of this size and capability. Compared to the standard output Cummins, the HO version commanded a higher price but offered a noticeable increase in power and performance. Compared to competing trucks from Ford and General Motors, the RAM 3500 was often cited as offering a more refined interior and a more comfortable ride.
Legacy
The 6.7 HO Cummins engine, paired with the Aisin automatic transmission, has proven to be a remarkably reliable powertrain. These trucks are still commonly seen on the road today, often with high mileage and extensive use. The Cummins engine is renowned for its longevity, and with proper maintenance, can easily exceed 300,000 miles. The Aisin transmission is also known for its durability. In the used car market, these RAM 3500s hold their value relatively well, particularly those in good condition with well-documented maintenance records. They remain a popular choice for buyers seeking a capable and reliable heavy-duty truck.
