The OEM radiator utilizes crimped plastic end tanks that become brittle from continuous thermal cycling and eventually crack or leak at the seams. Additionally, the factory tube-and-fin density offers limited heat dissipation surface area, leading to severe heat soak, rising transmission fluid temperatures, and potential premature engine failure when the L96 6.0L engine is under sustained heavy loads.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis full aluminum radiator utilizes an aerospace-grade Al-Mg alloy construction, eliminating the weak plastic tanks entirely. Featuring a massive 34 1\/16'' W x 23 1\/8'' H core, it incorporates a high-density tube and fin design that dramatically increases the surface area. This results in a 30% to 45% increase in cooling efficiency over the stock unit. TIG-welded for superior burst strength, it holds a significantly higher coolant capacity to resist temperature spikes. Integrated automatic transmission and engine oil coolers ensure all critical fluid temperatures are managed efficiently, keeping your rig out of the red during extreme conditions.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e2011-2019 Chevrolet Silverado 2500HD \/ 3500HD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eL96 6.0L V8 \/ GMT900 \u0026amp; K2XX HD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e360 hp \/ 380 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCU13301, 23447657, GM3010566\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFor 2011 - 2019 Chevrolet Silverado 2500 HD 6.0L Only\u003c\/li\u003e\n\u003cli\u003eFor 2011 - 2019 Chevrolet Silverado 3500 HD 6.0L Only\u003c\/li\u003e\n\u003cli\u003eFor 2015 - 2018 Chevrolet Silverado 3500 6.0L Only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Chevrolet Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eThe Silverado HD platform demands uncompromised reliability for heavy towing and hauling.
