Description

Upgrade your 2011–2016 Chevy or GMC Duramax 6.6L diesel truck with a Cold Case Performance Aluminum Radiator—engineered for heavy-duty cooling and precision OEM fitment. Crafted with 100% TIG-welded aluminum and polished tanks, this radiator provides exceptional performance and a clean, high-end under-hood appearance. Its oversized dual-row design significantly outperforms traditional 3- or 4-row radiators by increasing coolant volume and flow.

The crossflow-style core features 16 fins per inch and corrugated fins, delivering enhanced heat transfer and optimal airflow. Installation is seamless with its direct-fit, drop-in design for Silverado and Sierra HD models. Built to withstand the demands of towing, hauling, and high-output diesel performance, this radiator is 42.7% lighter than copper units while using thicker aluminum for long-lasting durability.
