DODGE RAM 3500 SERIES 2002-2004 SERVICE REPAIR WORKSHOP MANUAL
VEHICLE/EQUIPMENT INTRODUCTION:
The 2002 to 2004 Dodge Ram 3500 is the one-ton heavy-duty workhorse of the Ram lineup, designed for maximum payload and towing capacity. Available in both single rear wheel and dual rear wheel (DRW) configurations, the 3500 series features reinforced frame rails, heavier-duty axles, upgraded braking systems, and the strongest drivetrain components in the Ram family.
The defining powertrain for the Ram 3500 is the legendary 5.9-liter Cummins 24-valve turbo diesel engine. This inline-six diesel produces massive torque figures and is renowned for its ability to reliably exceed five hundred thousand miles with proper maintenance. Paired with the robust 48RE automatic or the bulletproof NV5600 six-speed manual transmission, the Ram 3500 Cummins combination is considered one of the finest diesel truck powertrains ever assembled.
Whether used for gooseneck trailer towing, commercial hauling, farm work, or as a personal truck capable of towing any recreational toy hauler, the Ram 3500 delivers unmatched capability. Its straightforward mechanical design means that owners who invest in proper service information and quality parts can maintain and repair their trucks at a fraction of dealer costs.
