Under sustained towing or ambient heat exceeding 90°F, continuous thermal expansion cycles fatigue the composite tanks. This leads to hairline fractures along the tank seams, degraded fin efficiency, and coolant loss, resulting in elevated cylinder head temperatures on the 5.7L HEMI.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered from high-tensile AA5052 aircraft-grade aluminum, this 3-row radiator features 100% TIG-welded end tanks, eliminating failure-prone crimped gaskets. The expanded 44 mm (1.73 in) core houses three parallel fluid rows, significantly increasing surface contact area and fluid dwell time. This construction promotes rapid convective heat transfer, preventing heat soak and keeping coolant temperatures stable under extreme payload demands.\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;\"\u003e2019-2021 RAM 1500\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;\"\u003e5.7L HEMI V8 \/ DT Chassis\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;\"\u003e395 hp \/ 410 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eCore Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e22.36\" x 27.48\" x 1.73\" (568 x 698 x 44 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet \/ Outlet\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.50\" \/ 1.77\"\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInterchange Part Numbers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eDPI13129, CU13129, PR13129A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2019 RAM 1500 (5.7L V8 Gas - Tradesman, Big Horn, Laramie, Rebel, Longhorn, Limited)\u003c\/li\u003e\n  \u003cli\u003e2020 RAM 1500 (5.7L V8 Gas - Tradesman, Big Horn, Laramie, Rebel, Longhorn, Limited)\u003c\/li\u003e\n  \u003cli\u003e2021 RAM 1500 (5.7L V8 Gas - Tradesman, Big Horn, Laramie, Rebel, Limited Longhorn, Limited)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe RAM Towing Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for rigorous hauling duty, this all-aluminum radiator withstands severe vibration and thermal shock, ensuring reliable operating temperatures when trailering heavy loads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50461755703544,"sku":"DS-EEEOFSJF8","price":218.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-ram-1500-2019-2021-5-7l-1.jpg?v=1788825133","url":"https:\/\/performancechiptuning.com\/es\/products\/aluminum-radiator-for-ram-1500-2019-2021-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
