Configuration decides the parts
A RAM 1500 of one model year covers regular, quad and crew cabs, two bed lengths, two- and four-wheel drive, several axle ratios and differential types, and coil or air rear suspension. The heavy-duty 2500 and 3500 add higher weight ratings, different axles and the Cummins diesel with its own service parts throughout.
Every one of those moves real components: brake lines and propshafts follow wheelbase, springs and dampers follow weight rating and suspension type, exhaust sections follow both plus the engine. The model name cannot resolve these differences. Select the vehicle record by VIN and check its configuration.
Mopar numbering
Current numbers are eight digits plus two revision letters — 68259752AB. The letters step AA, AB, AC as parts are updated, and on a truck range where parts are worked hard the revisions are frequent enough to matter. Read the supersession chain to its end rather than reordering the number on last year's invoice.
RAM and Dodge history
RAM became a separate brand in 2009; before that these trucks were Dodge Rams, and the catalog spans both eras continuously. A pre-2009 truck resolves the same way a current one does, with the numbering chains carried forward.

Frequently asked questions
Does the catalog cover pre-2009 Dodge Ram trucks?
Yes. RAM separated from Dodge in 2009 and the catalog spans both eras, with supersession chains carried forward.
How much does configuration change the parts list?
Substantially. Cab, bed length, drivetrain, axle ratio, suspension type and weight rating each change components. Select the vehicle record by VIN and check those details before choosing a part.
Is the Cummins diesel catalogued separately?
It is catalogued under the same models, with its own numbers throughout the fuel, intake, cooling and after-treatment groups.
