Powertrain & Engine Architecture
The heart of this RAM variant is the 6.7-liter Cummins ISB turbodiesel engine, designated with the ETJ code. This engine represents a significant advancement over previous Cummins designs used in Dodge/RAM trucks. It features a cast iron block, aluminum cylinder head, and a 24-valve configuration. The engine utilizes a high-pressure common rail fuel injection system, delivering fuel at extremely high pressures for optimized combustion and reduced emissions. The turbocharger, coupled with an intercooler, provides increased air intake, boosting power and torque output. The 6.7L Cummins is known for its durability and longevity, and is a favorite among diesel enthusiasts. This particular version, producing 350 horsepower and 827 Nm (609.96 lb-ft) of torque, was paired with a standard six-speed manual transmission. While an automatic transmission was available on other trims, the 350 hp version was exclusively offered with the manual.
Driving Characteristics
The 6.7L Cummins with the six-speed manual transmission delivers a robust and purposeful driving experience. The engine’s substantial torque is readily available from low RPMs, making it exceptionally capable for towing and hauling heavy loads. The manual transmission allows for precise control over gear selection, which is particularly beneficial when navigating challenging terrain or managing a trailer. Compared to the higher-output Cummins variants (typically around 385 hp), this version offers a slightly more relaxed power delivery, prioritizing usability and fuel efficiency. While not as quick accelerating as its more powerful siblings, the 350 hp version provides ample power for most tasks. The gear ratios in the six-speed manual are well-suited for both on-road cruising and off-road work.
Equipment & Trim Levels
The RAM 2500/3500 Regular Cab I with the 6.7L Cummins 350 hp engine typically represented a mid-range offering. Standard equipment included air conditioning, a basic audio system, vinyl upholstery, and manually adjustable windows and locks. The interior was functional and durable, designed to withstand the rigors of work-truck use. Optional extras included power windows and locks, upgraded audio systems, cloth or leather upholstery, and various towing packages. The Regular Cab configuration offered a simple, no-frills interior focused on practicality. The trim level was often designated as ST or SLT, with the SLT offering a few more convenience features.
Chassis & Braking
The chassis of the RAM 2500/3500 is a body-on-frame construction, providing a robust foundation for heavy-duty use. The front suspension utilizes a double wishbone setup, while the rear suspension employs leaf springs. This configuration is designed to handle substantial payloads and provide a comfortable ride, even when unladen. Braking duties are handled by ventilated discs at the front and discs at the rear, equipped with an Anti-lock Braking System (ABS) for enhanced safety. The braking system is appropriately sized for the truck’s weight and towing capacity. Steering is accomplished via a rack and pinion system, providing responsive and precise handling.
Market Reception & Comparison
The RAM 2500/3500 with the 6.7L Cummins 350 hp engine was generally well-received by critics and consumers alike. It was praised for its powerful engine, robust construction, and impressive towing capacity. Compared to the higher-output Cummins variants, this version offered a more affordable entry point into the heavy-duty truck market. Fuel economy, while not a primary concern for truck buyers, was respectable for a vehicle of this size and capability. Reliability was also a strong point, with the Cummins engine being known for its longevity. Compared to competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM 2500/3500 offered a compelling combination of performance, features, and value.
Legacy
The 6.7L Cummins engine, in all its iterations, has become legendary for its durability and reliability. The 350 hp version, while not the most powerful, remains a popular choice among owners seeking a dependable and capable work truck. These trucks continue to hold their value in the used car market, particularly those that have been well-maintained. The engine’s robust design and readily available parts ensure that these trucks can remain in service for many years to come. The 2010-2012 RAM 2500/3500 Regular Cab I with the 6.7L Cummins 350 hp engine represents a sweet spot in the heavy-duty truck market, offering a blend of capability, affordability, and long-term reliability.
