INTRODUCTION
The 2014-2018 RAM 2500/3500 Crew Cab Long I facelift represented a significant refresh of the second-generation RAM heavy-duty trucks. Built on the 2500/3500 platform, this variant featured the 6.7-liter Cummins HO (High Output) diesel engine, a popular choice for those needing substantial towing and hauling capacity. The “HO” designation indicated a higher power output compared to the standard Cummins offering. The combination of the Cummins engine, the Aisin automatic transmission, and the 4×4 drivetrain made this truck a workhorse capable of handling demanding tasks while still providing a relatively comfortable ride for a vehicle of its size and capability. The Crew Cab configuration offered ample passenger space, making it suitable for both work and family use.
Powertrain & Engine Architecture
The heart of this RAM variant is the 6.7-liter Cummins inline-six diesel engine, specifically the ETK code. This engine utilizes a turbocharger and intercooler to boost power and efficiency. The 6.7L Cummins HO engine is a direct-injection diesel, employing a Bosch common-rail fuel injection system capable of extremely high injection pressures. This system, combined with the advanced turbocharger design, contributes to the engine’s impressive torque output of 1152 Nm (849.67 lb-ft). The engine features an overhead valve (OHV) valvetrain, a design choice favored for its durability and simplicity. The Aisin six-speed automatic transmission, known for its robustness and smooth shifting, was specifically chosen to handle the high torque output of the Cummins engine. The transmission’s gear ratios are optimized for both towing and fuel economy, providing a balance between power delivery and efficiency.
Driving Characteristics
The 385 hp and 1152 Nm of torque delivered by this powertrain configuration translate into impressive real-world performance. While not as quick as some gasoline-powered trucks, the Cummins diesel provides a broad, flat torque curve, making it exceptionally capable of towing heavy loads. The Aisin transmission shifts smoothly and decisively, contributing to a confident driving experience. Compared to the standard Cummins engine, the HO version offers noticeably more power, particularly at higher RPMs. Compared to manual transmission equipped models, the automatic provides ease of use, especially in stop-and-go traffic or when navigating challenging terrain. However, some drivers may prefer the greater control offered by a manual gearbox. The 4×4 system provides excellent traction in various conditions, making this truck suitable for both on-road and off-road use.
Equipment & Trim Levels
The RAM 2500/3500 Crew Cab Long I (facelift 2013) with the 6.7 HO Cummins and automatic transmission was typically offered in mid-to-high trim levels, such as Laramie or Limited. Standard features often included cloth or leather upholstery, air conditioning, power windows and locks, a premium sound system, and a rearview camera. Optional extras could include a navigation system, heated and ventilated seats, a sunroof, and various driver-assistance features. The interior design focused on comfort and functionality, with a spacious cabin and user-friendly controls. The Crew Cab configuration provided ample rear-seat legroom, making it a comfortable option for passengers.
Chassis & Braking
The RAM 2500/3500 featured a robust chassis designed to withstand the stresses of heavy-duty use. The front suspension utilized an independent multi-link design, providing a comfortable ride and good handling characteristics. The rear suspension employed a traditional leaf spring setup, optimized for load-carrying capacity. Braking duties were handled by disc brakes on all four wheels, providing ample stopping power even when towing heavy loads. An Anti-lock Braking System (ABS) was standard, enhancing safety and control. Hydraulic power steering provided responsive and precise steering feel.
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, smooth transmission, comfortable ride, and spacious interior. Fuel economy, while not a primary concern for heavy-duty truck buyers, was considered reasonable for a vehicle of this size and capability. Compared to the standard Cummins engine, the HO version offered a noticeable performance improvement, justifying the higher price tag for many buyers. Compared to competitors from Ford and General Motors, the RAM 2500/3500 was often lauded for its ride quality and interior refinement.
Legacy
The 6.7-liter Cummins HO engine paired with the Aisin automatic transmission has proven to be a durable and reliable powertrain combination. These trucks continue to hold their value in the used car market, particularly those that have been well-maintained. The engine is known for its longevity and relatively low maintenance costs, making it a popular choice for those seeking a dependable heavy-duty truck. While modern trucks offer more advanced technology and features, the 2014-2018 RAM 2500/3500 with the 6.7 HO Cummins remains a capable and respected workhorse.
