Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2026 4500.
The 2026 Ram 4500 represents the current culmination of a model lineage tracked from 2008 to 2026, though this overview does not specify its underlying body, platform, or engine configurations. The vehicle's standout figures instead emerge from its complaint history, which remains remarkably restrained with a peak of just eight complaints in 2014 and a nadir of a single complaint in 2009. Occupying the final year of this documented timeline, the 2026 model inherits a proven reliability trajectory defined by minimal historical issues, meaning researchers can view this iteration as a mature and highly dependable entry in the lineup.
