⚙️ Engine Specifications

Engine Options Likely:

While specific engine variants are not detailed in the product description, the Dodge Ram 4000 DX Family of this era commonly featured Cummins turbodiesel engines, such as the 5.9L ISB.

Performance Details:

Performance figures are highly dependent on the specific engine and configuration chosen by the end-user or upfitter. Torque is a primary focus for this class of vehicle.

Fuel System Type:

Likely a high-pressure common rail (HPCR) diesel injection system for Cummins engines, or gasoline fuel injection for potential gasoline engine options.

Engine Control System Details:

Covers diagnosis and repair of the Engine Control Module (ECM) or Powertrain Control Module (PCM), including sensor inputs, actuator outputs, and diagnostic trouble codes (DTCs).

🔧 Transmission

Standard Transmission:

Likely a manual transmission (e.g., NV5600 6-speed) or an automatic transmission (e.g., Allison 1000/2000 series) for diesel variants, depending on configuration and GVWR.

Optional Transmission:

Automatic transmissions (e.g., Allison) were likely optional or standard on higher GVWR models, while manual transmissions were also common.

Transmission Features:

Heavy-duty construction, designed for high torque applications, potential PTO (Power Take-Off) provisions.

📐 Dimensions

Wheelbase Options:

Variable, depending on the specific chassis configuration and intended application (e.g., cutaway, chassis cab).

Gvwr Range:

Typically designed for Gross Vehicle Weight Ratings (GVWRs) in the Class 4-5 range, suitable for heavy-duty commercial use.

🛡️ Safety Features

Safety Rating Context:

As a commercial chassis, crash test ratings were less standardized compared to passenger vehicles, with focus on structural integrity for payload and driver protection.
