Keep your Duramax running cool with the Cold Case Performance Aluminum Radiator, engineered for 2006–2010 Chevy and GMC 6.6L diesel trucks. This premium TIG-welded aluminum radiator features a crossflow design, oversized dual cooling rows, and corrugated fins to maximize heat dissipation. Its polished finish offers both performance and a clean, show-ready look under the hood.

Designed for direct bolt-in installation, it fits factory shrouds and works with automatic transmissions.
