Under heavy loads, such as hauling heavy trailers up steep grades or running aggressive fuel tunes on the LBZ or LMM Duramax, the factory unit struggles to shed heat fast enough. This inefficiency leads to severe heat soak, elevated Engine Coolant Temperatures (ECT), and thermal stress that can compromise head gaskets. Furthermore, the constant thermal cycling causes the factory plastic end tanks to become brittle over time, eventually cracking at the crimp joints and resulting in sudden, catastrophic coolant loss.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eUpgrading to this 3-row, 100% TIG-welded aluminum radiator permanently eliminates the weak plastic end tanks. Featuring a massive 33 7\/8\" x 23 1\/2\" high-performance racing-spec core, this design increases overall fluid capacity and drastically improves the surface area available for heat dissipation. The high-density louvered tube-and-fin construction accelerates heat transfer, providing at least a 40% cooling efficiency increase over the stock unit. Additionally, it integrates a built-in transmission oil cooler with 7\/8-14UNF(P) fittings, ensuring your Allison transmission stays well within safe operating margins during grueling towing cycles.\u003c\/p\u003e\n  \n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\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;\"\u003e2006-2010 Chevrolet Silverado \/ GMC Sierra 2500HD \u0026amp; 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;\"\u003e6.6L Duramax V8 (LBZ \/ LMM) \/ GMT800 \u0026amp; GMT900\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;\"\u003e365 hp \/ 660 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;\"\u003e2857, DPI2857, CU2857, GM3010531, GM3010511, 15122835, 15914080, 15102152, 2858\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2006-2010 GMC Sierra 2500 HD SL SLE SLT WT 6.6L V8 DIESEL Turbocharged\u003c\/li\u003e\n    \u003cli\u003e2006-2010 GMC Sierra 3500 HD SL SLE SLT WT 6.6L V8 DIESEL Turbocharged\u003c\/li\u003e\n    \u003cli\u003eChevrolet Silverado 2500HD \/ 3500HD 6.6L V8 DIESEL Turbocharged (Cross-compatible platform)\u003c\/li\u003e\n    \u003cli\u003eSpecifically for LBZ\/LMM 6.6L V8 DIESEL Turbocharged Engines\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Heavy-Duty GM Durability Standard\u003c\/h3\u003e\n  \u003cp\u003eFor the GMT800 and GMT900 platforms, reliability under heavy load is paramount.
