If your 2003-2009 Dodge Ram 5.9L/6.7L Cummins is lacking in the cooling department, Mishimoto has the solution. Our essentials bundle is a great start to getting the most out of your 3rd Gen Ram. Included in this bundle is our Mishimoto aluminum radiator, performance transmission cooler, and silicone radiator hose kit.Our all-aluminum radiator is constructed from durable, TIG-welded end tanks to make it strong enough to withstand anything the road or the jobsite can throw at it. Our two-row core ensures efficient cooling for stock or modified trucks, while still fitting like stock. The included 1.3 bar high-pressure radiator cap and magnetic drain plug make sure coolant stays clean and where it belongs. To bridge the gap between the engine and the radiator, we've also included our silicone radiator hoses. These hoses are constructed from four layers of silicone and heat resistant fibers for greater heat and pressure tolerance. Just like the radiator, these hoses fit like stock without any trimming. While our radiator and coolant hoses keep your engine cool, our performance transmission cooler does the same for your transmission. This transmission cooler gives your Ram a 212-percent increase in core volume and 244-percent increase in fluid capacity over stock for maximum cooling. The fully serviceable thermostat with included bypass means that whether you live in a cold or hot environment, you never have to worry about a stuck thermostat ever again.Like all of our Dodge Ram Cummins parts, this 2003-2009 Dodge Ram Cummins Essentials bundle is protected by our Mishimoto Lifetime Warranty.
