The 8.1 crowd gets some love. Our new radiator is now available for 2003–2007 Chevy and GMC 2500/3500 trucks with the 8.1 Vortec and Allison transmission.
It uses the same extruded tube technology as our diesel lineup, adding strength and structural rigidity to the core- but especially making it LEAK FREE.
