Product Description

The Mishimoto MMRAD-RAM-13 performance aluminum radiator is a direct-fit replacement for Dodge Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.7 L Cummins I6 Turbo Diesel (2013-18). This heavy-duty truck radiator features a fully TIG-welded aluminum 3-row core that's 2" thick, boosting cooling capacity by 63% and surface area by 41% over stock units, making it ideal for towing and high-load applications. The robust construction resists cracking and corrosion for long-term durability.

Engineers designed it for everyday use and extreme conditions. It includes a magnetic drain plug to trap metallic particulates and comes equipped with fittings for the factory transmission cooler lines for hassle-free installation. While fitment is confirmed only through 2018, trucks in the 2019+ series use a new chassis and require the updated MMRAD-RAM-19; thus, fitment is confirmed through 2018 only. Installation difficulty is rated moderate - recommended for experienced DIY or professional installers.
