Mishimoto Performance Aluminum Radiator

2019–2024 Ram 2500 / Ram 3500 6.7L Cummins

MMRAD-RAM-19

Overview:

The Mishimoto Performance Aluminum Radiator is a premium cooling upgrade designed specifically for the 2019 to 2024 Ram 2500 and Ram 3500 trucks equipped with the 6.7L Cummins engine. Known for its legendary reliability and power, the Cummins-powered Ram is a workhorse built to handle heavy-duty tasks. However, the stock radiator’s plastic end tanks are prone to cracking and leaking under stress, especially when hauling or towing demanding loads. Mishimoto’s all-aluminum radiator addresses these weaknesses by offering enhanced durability and superior cooling performance, ensuring your Ram stays cool and reliable no matter the workload.

Engineered to withstand the rigors of heavy use, this radiator is an ideal upgrade for owners who demand more from their trucks. Whether you’re towing, hauling, or working in extreme conditions, the Mishimoto radiator provides peace of mind with increased fluid capacity and robust construction.

Key Features:

Designed to maximize cooling efficiency and durability, the Mishimoto Performance Aluminum Radiator offers the following key benefits:

• Durable fully aluminum construction with TIG-welded end tanks and fittings for superior strength and leak resistance
• 28% increase in fluid capacity compared to stock radiators, improving heat dissipation under heavy loads
• Includes replacement bushings to ensure a secure fit and reduce vibration from worn or damaged factory bushings
• Direct fitment for a wide range of Ram 2500 and Ram 3500 trims from 2019 through 2024, including Big Horn, Laramie, Limited, Rebel, Tradesman, and more
