Differential thermal expansion between the factory ductile iron casting and aluminum cylinder heads places excessive shear stress on the rearward hardware (cylinders 7 and 8). Over repeated heat cycles, OEM manifolds warp, fatigue, and snap the rear mounting studs, yielding the notorious cold-start exhaust tick, elevated exhaust gas temperatures (EGTs), and lost scavenging efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for the 4th Generation \u003cstrong\u003eDS \/ DJ \/ D2\u003c\/strong\u003e platform, this high-flow manifold is poured from high-tensile, heat-stabilized cast iron to mitigate dimensional deformation under sustained load. The casting features optimized internal runner geometry to minimize boundary layer turbulence and backpressure against the cylinder head. To permanently resolve hardware sheer, this kit integrates extended fasteners paired with engineered thermal spacers, allowing the assembly to absorb thermal growth without yielding the studs or blowing the exhaust gasket.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-flow cast iron exhaust manifold\u003c\/li\u003e\n  \u003cli\u003eHeat shield\u003c\/li\u003e\n  \u003cli\u003eExhaust manifold gasket\u003c\/li\u003e\n  \u003cli\u003eExtended mounting fasteners and expansion spacers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2009-2024 Ram, Dodge Ram 1500, 2500, 3500 (Classic \/ 4th Gen)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e5.7L HEMI (EZC\/EZH) \/ DS, DJ, D2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e395 hp \/ 410 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2018 Dodge Ram \/ Ram 1500 5.7L HEMI\u003c\/li\u003e\n  \u003cli\u003e2019-2024 Ram 1500 Classic (DS Body Style ONLY) 5.7L HEMI\u003c\/li\u003e\n  \u003cli\u003e2010-2018 Ram 2500 5.7L HEMI\u003c\/li\u003e\n  \u003cli\u003e2010-2018 Ram 3500 5.7L HEMI\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the DS \/ DJ \/ D2 Ram 1500, 2500, 3500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on fit for 2009-2024 trucks equipped with the \u003cstrong\u003e5.7L HEMI\u003c\/strong\u003e; it fits the 4th Generation Classic body style only and does not fit 5th Gen (DT) new body style models or 3.6L\/6.4L engines.\u003c\/p\u003e\n\n\u003ch4\u003eAre specialized thermal expansion spacers and bolts included with the kit?\u003c\/h4\u003e\n\u003cp\u003eYes, this kit supplies extended fasteners and dedicated spacers specifically engineered to handle cast iron expansion under high towing loads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ram Heavy-Duty Towing Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle extreme commercial duty cycles and maximum GCWR hauling, this heavy-duty iron manifold delivers leak-free reliability, robust heat resistance, and restored low-end towing torque without recurring hardware failures.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67584530972920,"sku":"DS-ELOR5V4JL","price":549.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-flow-exhaust-manifold-for-dodge-ram-2009-2024-5-7l-1.webp?v=1791316254","url":"https:\/\/performancechiptuning.com\/fr\/products\/high-flow-exhaust-manifold-for-dodge-ram-2009-2024-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
