A 2nd Gen Swap 6.7 Cummins 4th gen is a relatively new engine swap option available for Dodge Ram 2500 and 3500 trucks from 2007 through 2020. This swap combines the legendary power and reliability of the popular 6.7 liter Cummins turbo diesel engine with the classic body style of the second generation Dodge Rams, creating one powerful vehicle that looks as good as it performs. The 2nd Gen Swap was designed to increase torque output, improve fuel economy, and give owners more control over their truck’s performance by allowing them to customize their ride with aftermarket parts like ECU tuning, exhaust systems, injectors and turbos. With this setup you can expect up to an additional 50 horsepower or so compared to stock models while still retaining excellent longevity and reliability thanks in part to its durable design which includes a reinforced block made out of cast iron and forged connecting rods that are capable of handling higher levels of stress without breaking down prematurely.
