2012 Ram 3500: What's New, Specs & Features
Last updated August 4, 2026

The 2012 Ram 3500 is a light-update year led by an expanded trim lineup rather than a redesign. The core truck, including its 6.7-liter Cummins diesel hardware, carries over.
About the 2012 Ram 3500
4th-generation Ram Heavy Duty (2010-2012), final year before the extensively reworked 2013 HD trucks.
The 2012 Ram 3500 is Ram's one-ton tow-and-haul pickup for buyers who need serious diesel pulling power but still want a more comfortable cabin than a stripped commercial truck. Its core appeal is the 6.7L Cummins diesel, factory exhaust brake, huge towing capability, and a wide trim spread that runs from basic ST work trucks to upscale Longhorn models. Compared with rivals, Ram leaned heavily on torque, cabin space, and richer interiors without giving up heavy-duty credibility.
The 2012 range stretches from the vinyl-seat ST work truck to the leather-lined Longhorn models. Big Horn and Lone Star bring premium cloth and a power driver's seat to the middle of the lineup, while Outdoorsman adds an anti-spin rear differential, heavy-duty shocks, and tow hooks. Laramie focuses on comfort and tech with heated leather seats, navigation, and a rearview camera.
