INTRODUCTION
The Ram 2500/3500 series, particularly the Crew Cab Long II configuration, has become a mainstay for American truck buyers needing serious capability. The 2025 facelift brought updated styling and technology, but the core strength of these trucks remains their robust powertrains. The 3500 model with the 6.7-liter Cummins HO and TorqueFlite transmission, especially in the DRW configuration, is geared towards those who regularly tow heavy loads – fifth-wheel trailers, large equipment, or substantial payloads. This specific combination offers a balance between power, durability, and usability, making it a popular choice for commercial users and dedicated enthusiasts.
Powertrain & Engine Architecture
At the heart of this variant lies the Cummins 6.7-liter inline-six diesel engine. This engine, designated as the HO (High Output) version, produces 430 horsepower at 2800 rpm and a massive 1458 Nm (1075.37 lb.-ft.) of torque at 1800 rpm. The engine utilizes a diesel commonrail fuel injection system, delivering precise fuel metering for optimal combustion and efficiency. The engine features an overhead valve (OHV) valvetrain, known for its simplicity and reliability. A turbocharger and intercooler work in tandem to boost power and reduce exhaust emissions. The TorqueFlite 8-speed automatic transmission is specifically tuned to handle the engine’s substantial torque output, providing smooth and efficient gear changes. The DRW configuration (Dual Rear Wheels) further enhances stability and load-carrying capacity.
Driving Characteristics
The 6.7-liter Cummins HO with the TorqueFlite automatic delivers a driving experience focused on capability rather than outright speed. While 430 horsepower is substantial, the engine’s strength lies in its immense low-end torque. This allows for effortless towing and hauling, even with heavy loads. The 8-speed automatic transmission keeps the engine in its optimal power band, providing responsive acceleration. Compared to the standard output Cummins, the HO version offers a noticeable increase in power, particularly when towing uphill or accelerating with a load. Compared to gasoline-powered Ram 2500/3500 models, the diesel offers significantly more torque and better fuel economy when towing. The DRW setup provides enhanced stability, especially when carrying heavy payloads or towing large trailers, but it also results in a wider turning radius.
Equipment & Trim Levels
The 2025 Ram 2500/3500 Crew Cab Long II 3500 6.7 Cummins HO DRW typically comes standard with a well-equipped interior, including cloth upholstery, air conditioning, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a rearview camera. Higher trim levels, such as Laramie, Longhorn, and Limited, add premium features like leather upholstery, heated and ventilated seats, a premium sound system, and advanced safety technologies. Optional extras include a sunroof, navigation system, and various driver-assistance features.
Chassis & Braking
The Ram 2500/3500 chassis is built for durability and strength. The front suspension utilizes coil springs and a rigid axle with a transverse stabilizer bar. The rear suspension features a rigid axle with leaf springs, with optional air suspension available for improved ride comfort and load leveling. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. The front brakes measure 359.9×39.1 mm, while the rear brakes are 357.9×34 mm. An Anti-lock Braking System (ABS) is standard.
Market Reception & Comparison
The Ram 2500/3500 series, and particularly the Cummins-powered variants, consistently receive positive reviews for their capability, durability, and ride quality. Critics praise the 6.7-liter Cummins HO engine for its impressive torque output and smooth power delivery. The TorqueFlite transmission is also well-regarded for its responsiveness and reliability. Compared to competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the Ram 2500/3500 often stands out for its comfortable interior and refined driving experience. Fuel economy is competitive for a heavy-duty truck, but it’s still significantly lower than that of lighter-duty pickups.
Legacy
The Cummins 6.7-liter engine has earned a reputation for exceptional longevity and reliability. Properly maintained, these engines can easily exceed 300,000 miles. The 2025 Ram 2500/3500 3500 6.7 Cummins HO DRW is expected to hold its value well in the used car market, due to its strong demand and proven track record. The DRW configuration, while less common than single-rear-wheel models, is highly sought after by those needing maximum towing and payload capacity. This variant represents a sweet spot in the Ram lineup, offering a compelling combination of power, capability, and durability for years to come.
