Special Note for Dodge Ram (Classic/DT/DS)

Since Dodge/Ram manufacturered concurrent Ram 1500, 2500 & 3500 models on both new and old body designs, please ensure you select the parts to suit the correct submodel. The year alone may not always be a reliable way to verify your submodel in the case of some Rams, so we encourage you to double check if you have the Classic, or the new shape when making orders for parts that are not the identical between both styles.

Mishimoto performance radiators are designed and engineered to maximize cooling efficiency, boost engine functions, and, most of all, protect your engine from overheating.

Key features and benefits of Mishimoto performance radiators include:
• Available for universal and exact fit applications (no cutting or modifications required)
• All-aluminum construction for optimal heat dissipation, improved strength, and reliability
• Increased cooling capacity due to their massive core size
• 100 percent brazed aluminum core for minimal distortion, low stress, and clean joints
• Available in various sizes with 2-row or 3-row cores
• TIG-welded for clean, strong welds and increased durability
• Magnetic drain plugs capture metallic debris or fragments
• Included high-pressure 1.3 bar cap raises the coolant boiling point for greater safety and efficiency
• Automatic transmission and accessory coolers included where applicable
