2012 RAM 25003500 Crew Cab I 3500 6.7 HO Cummins TD (350 Hp) DRW

The RAM 2500/3500 Crew Cab I, specifically the 3500 model equipped with the 6.7 HO Cummins turbocharged diesel engine producing 350 horsepower, represents a significant iteration in the heavy-duty truck segment. Introduced for the 2012 model year, this variant occupied a crucial position within the RAM lineup, bridging the gap between the standard 2500 models and the more powerful, often work-focused, 3500 configurations. This particular version, often found in Dual Rear Wheel (DRW) configuration, was aimed at buyers needing substantial towing and payload capacity without necessarily requiring the absolute maximum output offered by other Cummins options. Production for this specific configuration ran through the 2012 model year, marking a relatively short but impactful period in the evolution of the RAM heavy-duty trucks.

Technical Specifications

Powertrain & Engine Architecture

At the heart of this RAM 3500 lies the 6.7-liter Cummins HO (High Output) turbodiesel engine, designated with the ETJ code. This inline-six cylinder engine represents a cornerstone of Cummins’ reputation for durability and torque. The “HO” designation signifies an upgraded turbocharger and fuel injection system compared to the standard 6.7L Cummins offered in the 2500 series. The engine utilizes a diesel commonrail fuel injection system, delivering highly pressurized fuel directly into the cylinders for optimized combustion. The overhead valve (OHV) valvetrain, while a more traditional design, contributes to the engine’s robustness and ease of maintenance. The 6.7L Cummins is known for its cast iron block, a key factor in its longevity. The engine produces 350 horsepower at 3000 rpm and a substantial 881 lb-ft of torque at 1500 rpm, making it exceptionally well-suited for heavy towing and hauling. The 6-speed manual transmission was the standard offering, providing drivers with full control over the engine’s powerband.

Driving Characteristics

The 3500 with the 6.7 HO Cummins and manual transmission delivers a driving experience focused on capability rather than outright speed. The engine’s peak torque is available at a relatively low 1500 rpm, providing ample pulling power from a standstill or during highway passing maneuvers. While the 350 horsepower is respectable, the true strength of this powertrain lies in its ability to effortlessly handle heavy loads. The manual transmission, while requiring more driver involvement than an automatic, allows for precise gear selection and maximizes control when towing. Compared to the standard 6.7L Cummins, the HO version offers a noticeable increase in power, particularly at higher engine speeds. However, it doesn’t match the performance of the even more powerful Cummins options available in the 3500 lineup, which were geared towards more demanding commercial applications.

Equipment & Trim Levels

The RAM 2500/3500 Crew Cab I 3500 6.7 HO Cummins TD (350 Hp) DRW typically came standard with a robust set of features designed for work and comfort. Standard equipment included air conditioning, power windows and locks, a basic audio system, and vinyl upholstery. The Crew Cab configuration provided ample space for passengers, making it a practical choice for families or work crews. Optional extras included leather upholstery, a premium sound system, navigation, and various towing packages. Trim levels varied, but generally offered increasing levels of luxury and convenience features. The DRW configuration (Dual Rear Wheels) was often paired with this engine for maximum stability and payload capacity.

Chassis & Braking

The chassis of the RAM 3500 is built around a heavy-duty frame designed to withstand significant stress. The front suspension utilizes a double wishbone setup, while the rear suspension employs leaf springs, a traditional design favored for its load-carrying capacity. Brakes are disc brakes on all four wheels, providing adequate stopping power even when heavily loaded. An Anti-lock Braking System (ABS) was standard, enhancing safety and control. The DRW configuration significantly increases the vehicle’s stability, particularly when towing. Tire sizes varied depending on the trim level and options selected, with common sizes including 245/70 R17, 265/70 R17, and 275/70 R18.

Market Reception & Comparison

The RAM 2500/3500 with the 6.7 HO Cummins engine received generally positive reviews from critics and buyers alike. It was praised for its robust powertrain, impressive towing capacity, and comfortable ride quality. Compared to competing trucks from Ford and Chevrolet, the RAM offered a compelling combination of power, capability, and value. Fuel economy, as expected for a heavy-duty diesel truck, was not a primary strength, but the engine’s longevity and relatively low maintenance costs helped offset this concern. The manual transmission was appreciated by those who preferred greater control, but some buyers opted for the available automatic transmission for added convenience.

Legacy

The 6.7 HO Cummins engine has proven to be exceptionally reliable over the long term, with many examples exceeding 200,000 miles with proper maintenance. The 2012 RAM 3500 with this powertrain remains a popular choice in the used truck market, particularly among buyers seeking a capable and durable work truck. Its reputation for reliability and strong resale value contribute to its continued desirability. While newer RAM trucks offer more advanced technology and features, the 2012 model represents a sweet spot for those seeking a proven and dependable heavy-duty truck at a reasonable price.
