The RAM 1500 Crew Cab (DS) equipped with the 5.7 Hemi V8 engine and a four-wheel drive (4×4) automatic transmission was a popular configuration produced between 2010 and 2012. This variant represented a sweet spot in the fourth-generation (DS) RAM 1500 lineup, offering a balance of capability, comfort, and features for the North American truck market. It was positioned as a mid-to-upper trim level, appealing to buyers needing substantial towing capacity and passenger space without opting for the range-topping luxury trims.

Powertrain & Engine Architecture
At the heart of this RAM 1500 variant lies the 5.7-liter HEMI V8 engine, internally designated as the EZH. This engine is a member of Chrysler’s third-generation HEMI family, reintroduced in 2003. It features a cast iron block, aluminum cylinder heads, and a two-valve-per-cylinder (OHV) configuration. The engine utilizes a multi-point fuel injection system, delivering fuel directly to each intake port. The 5.7L HEMI is known for its robust construction and relatively simple design, contributing to its longevity. The engine’s Variable Valve Timing (VVT) system optimizes performance and fuel efficiency across the rev range. Paired with the engine is a five-speed automatic transmission (typically the 545RFE), chosen for its durability and ability to handle the engine’s substantial torque output. This transmission featured electronically controlled shifting and overdrive for improved highway fuel economy.
Driving Characteristics
The 390 horsepower and 407 lb-ft of torque delivered by the 5.7 Hemi V8 provided ample power for everyday driving and towing. While not as quick as the higher-output 6.1L HEMI or the diesel variants, the 5.7L offered a smooth and responsive driving experience. The automatic transmission, while not offering the most aggressive shift points, provided seamless gear changes. The 4×4 system, typically an electronically controlled part-time system, allowed drivers to switch between two-wheel drive for fuel efficiency and four-wheel drive for enhanced traction in inclement weather or off-road conditions. Compared to the manual transmission equipped 5.7L models, the automatic offered a more relaxed driving experience, particularly in city traffic. However, the manual transmission generally provided slightly better fuel economy and a more direct connection to the engine.
Equipment & Trim Levels
The Crew Cab (DS) configuration, combined with the 5.7 Hemi and 4×4, typically came standard with features like air conditioning, power windows and locks, a basic audio system, and cloth upholstery. Higher trim levels, such as the Laramie, added features like leather upholstery, heated seats, a premium audio system, and chrome exterior accents. Optional extras included a navigation system, a sunroof, and various towing packages. The Crew Cab body style provided generous interior space, comfortably seating up to six passengers. The interior design was functional and durable, prioritizing practicality over outright luxury.
Chassis & Braking
The RAM 1500 utilized a body-on-frame construction, providing a robust and durable platform. The front suspension featured a double wishbone design, while the rear suspension employed an independent multi-link setup. This combination aimed to balance ride comfort with handling stability. Braking duties were handled by ventilated disc brakes at all four corners, coupled with an Anti-lock Braking System (ABS) for enhanced safety. The 4×4 system included a transfer case allowing the driver to select between 2H (two-wheel drive high range), 4H (four-wheel drive high range), and 4L (four-wheel drive low range) for optimal traction in various conditions.
Market Reception & Comparison
The RAM 1500 Crew Cab 5.7 Hemi 4×4 Automatic was well-received by the American truck-buying public. Critics praised its comfortable ride, spacious interior, and strong towing capacity. Fuel economy, however, was a common criticism, typical for a full-size pickup truck with a V8 engine. Compared to the diesel-powered RAM 1500 models, the 5.7 Hemi offered lower initial cost but higher fuel consumption. Against competitors like the Ford F-150 and Chevrolet Silverado, the RAM 1500 was often seen as offering a more comfortable ride and a more refined interior.
Legacy
The 5.7 Hemi V8 engine has proven to be a remarkably durable and reliable powertrain. Many examples of the 2010-2012 RAM 1500 continue to be on the road today, often with high mileage. The engine’s relatively simple design and robust construction contribute to its longevity. In the used car market, these trucks remain popular choices for buyers seeking a capable and comfortable full-size pickup. Maintenance is generally straightforward, and parts availability is excellent. While older models may require routine maintenance items like oil changes and spark plug replacements, the 5.7 Hemi is generally considered a reliable engine, making these RAM 1500s a solid value in the used truck market.
