Construction & Design

Constructed entirely from 100% brazed aluminum, this radiator balances lightweight design with exceptional strength. The two-row core is 19% thicker than the original equipment manufacturer (OEM) radiator, allowing for greater coolant volume and more efficient heat transfer. The end tanks are precision TIG-welded using robotic technology, ensuring consistent weld quality and durability under high-pressure conditions.

Strategic side plates on the end tanks channel airflow directly into the radiator core, maximizing cooling efficiency. The brushed aluminum finish not only resists corrosion but also adds a sleek, professional look under the hood. Every design element focuses on enhancing performance while maintaining long-term reliability in demanding diesel truck environments.

Installation & Fitment

This radiator is engineered as a direct factory replacement for 2010–2012 Dodge Ram 2500 and 3500 models equipped with the 6.7L Cummins diesel engine. Installation is straightforward and requires no cutting, trimming, or modifications to existing mounting points or hoses. The included rubber mounting bushings reduce vibration and ensure a secure fit, while the magnetic drain plug simplifies coolant changes and system maintenance.

Owners can expect a hassle-free upgrade experience that improves cooling performance without compromising factory fitment or vehicle aesthetics.
