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

The RAM 2500/3500 Regular Cab I, specifically the 3500 model equipped with the 6.7 HO Cummins turbocharged diesel engine and a six-speed automatic transmission, represents a significant offering in the American heavy-duty pickup truck market. Introduced for the 2012 model year, this configuration was designed for buyers needing substantial towing and payload capacity. It occupied a position within the RAM lineup geared towards commercial users, farmers, and individuals requiring a robust work truck, falling between the lighter-duty 1500 series and the even more capable, but often more expensive, specialized 3500 configurations. The “HO” designation indicated a higher output version of the 6.7L Cummins, providing increased horsepower and torque compared to the standard engine option.

Technical Specifications

Powertrain & Engine Architecture

The heart of this RAM 3500 is the 6.7-liter Cummins ETJ inline-six diesel engine. This engine is a robust, over-head valve (OHV) design known for its durability and low-end torque. The “HO” variant featured a larger turbocharger and revised fuel injection settings compared to the standard 6.7L Cummins, resulting in the 350 horsepower and 1084 Nm (799.52 lb-ft) of torque. The engine utilizes a Bosch common-rail fuel injection system, delivering highly pressurized fuel directly into the cylinders for efficient combustion. The six-speed automatic transmission, sourced from Allison, was specifically calibrated to handle the engine’s substantial torque output. This transmission featured electronically controlled shifting and a tow/haul mode optimized for heavy loads.

Driving Characteristics

The 3500 with the 6.7L HO Cummins and automatic transmission delivers a driving experience focused on capability rather than outright speed. While 350 horsepower is respectable, the true strength lies in the massive 1084 Nm of torque available from a relatively low 1500 rpm. This translates to effortless towing and hauling, even with substantial payloads. The automatic transmission shifts smoothly, but isn’t particularly quick or sporty. Compared to manual transmission equipped versions, the automatic offers convenience but sacrifices some driver control and potentially a slight reduction in fuel economy. The gear ratios are optimized for pulling power, meaning acceleration is brisk but not exhilarating. The truck feels planted and stable, even when heavily loaded, thanks to its heavy-duty suspension and robust chassis.

Equipment & Trim Levels

The 2500/3500 Regular Cab I 3500 6.7 HO Cummins TD Automatic DRW typically came with a fairly basic level of standard equipment, reflecting its work-truck orientation. Standard features generally included air conditioning, a basic audio system, vinyl upholstery, and manually adjustable windows and locks. Optional extras included power windows and locks, upgraded audio systems, cruise control, and various towing packages. Interior trim was functional and durable, prioritizing practicality over luxury. The Regular Cab configuration offered seating for two or three occupants, with a focus on maximizing cargo space in the bed.

Chassis & Braking

The chassis of the RAM 3500 is a fully boxed frame constructed from high-strength steel, designed to withstand the stresses of heavy-duty use. The front suspension utilizes a double wishbone setup, while the rear suspension employs a traditional leaf spring design. This combination provides a comfortable ride, even when unladen, and excellent load-carrying capacity. Braking duties are handled by disc brakes on all four wheels, coupled with an Anti-lock Braking System (ABS) for enhanced safety. The Dual Rear Wheel (DRW) configuration significantly increases stability and load capacity compared to single rear wheel models.

Market Reception & Comparison

The 2012 RAM 3500 with the 6.7L HO Cummins and automatic transmission was generally well-received by critics and buyers alike. It was praised for its immense towing and payload capacity, robust engine, and comfortable ride. Compared to competitors like the Ford Super Duty and Chevrolet Silverado HD, the RAM 3500 offered a compelling combination of power, capability, and value. Fuel economy, while not a primary concern for buyers in this segment, was generally comparable to other heavy-duty diesel trucks. Reliability was also a strong point, with the Cummins engine being renowned for its longevity.

Legacy

The 6.7L Cummins engine, in both its standard and HO forms, has become legendary for its durability and reliability. These engines are known to easily exceed 240,000 kilometers (150,000 miles) with proper maintenance, and many continue to operate well beyond that mileage. On the used car market, these RAM 3500s hold their value relatively well, particularly those in good condition with well-documented maintenance histories. The combination of a powerful engine, robust transmission, and heavy-duty chassis makes this a desirable truck for buyers seeking a capable and long-lasting workhorse. Common maintenance items include regular oil changes, fuel filter replacements, and occasional attention to the cooling system. Overall, the 2012 RAM 3500 6.7 HO Cummins Automatic DRW remains a respected and capable truck, even years after its initial release.
