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

The RAM 2500/3500 Crew Cab I, specifically the 3500 model equipped with the 6.7 HO Cummins turbocharged diesel engine and automatic transmission, represents a significant offering in the American heavy-duty pickup truck market. Introduced for the 2012 model year, this configuration aimed to provide a balance of substantial towing capacity, robust performance, and a degree of everyday usability for owners needing a powerful work truck. It falls within the first generation of the redesigned 2500/3500 series, known for its enhanced interior and improved ride quality compared to previous iterations. This variant positioned itself as a step up from the standard 6.7L Cummins, offering increased horsepower and torque for demanding tasks.

Technical Specifications

Powertrain & Engine Architecture

At the heart of this RAM 3500 lies the 6.7-liter Cummins HO (High Output) turbodiesel inline-six engine, designated with the ETJ code. This engine is a robust and well-regarded powerplant known for its durability and torque production. The “HO” designation signifies an upgraded turbocharger and fuel injection system 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 direct fuel injection system, delivering highly pressurized fuel directly into the cylinders for optimized combustion. The valvetrain employs an overhead valve (OHV) configuration, a traditional design favored for its simplicity and reliability. The automatic transmission paired with this engine is a heavy-duty six-speed unit, designed to handle the substantial torque output and provide smooth shifting under load. This transmission was specifically calibrated to work with the Cummins engine’s powerband, offering optimal performance for towing and hauling.

Driving Characteristics

The 3500 with the 6.7 HO Cummins and automatic transmission delivers a driving experience focused on capability rather than outright speed. While 350 horsepower is respectable, the true strength of this powertrain lies in its immense torque. This translates to effortless acceleration, even when heavily loaded or towing a substantial trailer. The automatic transmission provides smooth and predictable shifts, although it may not be as responsive as a manual transmission. The gear ratios are optimized for towing, with lower gears providing ample pulling power and higher gears offering comfortable highway cruising. Compared to the standard 6.7L Cummins, the HO version offers noticeably more power, particularly when climbing hills or accelerating with a load. However, it doesn’t offer the same level of fuel efficiency as the lower-output engine. The leaf spring rear suspension, while providing excellent load-carrying capacity, can result in a firmer ride when the truck is unloaded.

Equipment & Trim Levels

The RAM 2500/3500 Crew Cab I 3500 6.7 HO Cummins Automatic was typically offered in several trim levels, including STX, SLT, Laramie, and Limited. The base STX trim provided essential features such as air conditioning, power windows and locks, and a basic audio system. The SLT trim added features like upgraded cloth upholstery, keyless entry, and a more advanced audio system. The Laramie trim offered leather upholstery, heated front seats, a premium audio system, and chrome exterior accents. The top-of-the-line Limited trim included all the features of the Laramie trim, plus additional luxury features such as ventilated front seats, a navigation system, and a rear-seat entertainment system. Standard features across most trims included a spacious Crew Cab interior, providing ample room for passengers, and a robust four-wheel drive system (optional).

Chassis & Braking

The chassis of the RAM 2500/3500 is built around a heavy-duty frame designed to withstand the stresses of demanding work. The front suspension utilizes a double wishbone design, providing a comfortable ride and good handling. The rear suspension employs a traditional leaf spring setup, optimized for load-carrying capacity. Braking duties are handled by disc brakes on all four wheels, providing ample stopping power even when heavily loaded. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. Tire sizes varied depending on the trim level and options selected, ranging from 245/70 R17 to 275/70 R18.

Market Reception & Comparison

The RAM 2500/3500 with the 6.7 HO Cummins and automatic transmission was generally well-received by critics and consumers alike. It was praised for its powerful engine, robust construction, and comfortable interior. Compared to its competitors, such as the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM offered a compelling combination of performance, features, and value. Fuel economy, however, was a common criticism, as is typical for heavy-duty diesel trucks. The Cummins engine’s reputation for reliability also contributed to its popularity. Owners often reported excellent long-term durability, even with high mileage and demanding use.

Legacy

The 6.7 HO Cummins engine paired with the six-speed automatic transmission has proven to be a remarkably durable and reliable powertrain. These trucks continue to be popular in the used car market, commanding relatively high prices due to their reputation for longevity and capability. While maintenance costs can be higher than those of gasoline-powered trucks, the Cummins engine’s robust construction and readily available parts supply make it a relatively easy engine to maintain. The 2012 RAM 2500/3500 Crew Cab I 3500 6.7 HO Cummins TD Automatic remains a testament to American truck engineering, offering a potent combination of power, durability, and practicality.
