¹ With the 4.10 axle ratio: the maker’s figure for the configuration with that factory option.

A dash means the maker’s documents we have don’t give that number for that configuration, and a column with no number for any configuration of the year isn’t shown. “Door label” means the maker prints it only on each vehicle’s certification label, and “not published” that the maker doesn’t print it, or points elsewhere. “Up to” is a ceiling the maker prints over several configurations; a range is the maker’s own, printed across the grades of that configuration.

The 2018 documents

3 documents behind the 2018 Ram 2500’s figures. The maker’s own come first; a third-party page fills in only a number the maker doesn’t publish, and wears its own mark.

Documents last checked Oct 12, 2026. How we read them and what the marks mean: how we source the numbers. A figure doesn’t match its document? Report a wrong number.

These are Ram’s published figures for the models it describes, not a weighbridge or a tape measure; your own vehicle’s options change them. Found a figure that doesn’t match the document? Tell us.
