The 4th generation Ram 2500/3500, introduced in 2010 and produced until 2018, represents a significant milestone in the evolution of Cummins-powered pickups.
Known for its timeless design, impressive towing capacity, and the powerhouse 6.7-liter Cummins diesel engine, this generation solidified Ram's reputation as a leader in the diesel truck market—with many owners preferring them to even newer, more modern options.
Design and Features
Ram redesigned the 4th generation to balance modern aesthetics with traditional toughness. The exterior received a bold grille, aerodynamic improvements, and sharper lines that enhanced both appearance and performance.
The interior was upgraded significantly, offering a range of trims from utilitarian work trucks to luxurious models featuring leather seats, advanced infotainment systems, and premium sound systems.
Many enthusiasts consider the 2013-2018 Ram 2500/3500 to be the most desirable 4th Gen Ram—as the 2010-2012 model years did not receive all the updates.
Innovative storage solutions, such as the RamBox Cargo Management System, added to the truck's practicality, providing secure, weatherproof storage compartments integrated into the bed walls.
The 6.7 Cummins Diesel Engine
One of the standout features of the 4th generation Ram trucks is the availability of the 6.7-liter Cummins Turbo Diesel engine. This inline-six engine, first introduced halfway through 2007, the 6.7 continued to evolve throughout the 4th generation, offering improvements in power, torque, and efficiency.
Performance
The 6.7 Cummins engine was available in multiple configurations depending on the year and trim level, with power outputs ranging from 350 to over 385 horsepower and torque figures climbing as high as 930 lb-ft by the end of the generation.
This remarkable torque allowed the truck to achieve best-in-class towing capabilities, with maximum towing capacities exceeding 31,000 pounds when properly equipped.
Reliability and Durability
The Cummins engine is renowned for its durability and long service life, making it a favorite among truck enthusiasts and professionals who demand reliability. Features such as a cast-iron block, forged-steel crankshaft, and high-pressure common-rail fuel injection system contributed to the engine's robust performance and efficiency.
Emissions and Innovations
To meet increasingly stringent emissions standards in 2007, the 6.7 Cummins incorporated advanced systems such as Selective Catalytic Reduction (SCR), Diesel Particulate Filter (DPF), and Exhaust Gas Recirculation (EGR).
While these systems helped reduce environmental impact, they also introduced complexity, requiring proper maintenance to ensure optimal performance.

-
6-Speed Manual Transmission: A favorite for purists and those seeking maximum control, the G56 manual transmission offered simplicity and rugged dependability.
