Because cast iron and cast aluminum expand at vastly different thermal rates, prolonged towing cycles and high operating temperatures induce lateral shear across the cylinder deck. Over time, OEM composite gaskets degrade, resulting in coolant weeping at the rear cylinders, loss of combustion seal, and oil seepage around the timing cover and valve guides.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive overhaul kit features robust multi-layer steel (MLS) head gaskets engineered with high-recovery embossed combustion fire rings. The steel core withstands elevated cylinder pressures and thermal scrub without crushing or distorting. Paired with high-grade Viton valve stem seals and pre-formed elastomer oil pan and manifold seals, this set prevents vacuum loss, controls oil consumption, and maintains seal integrity across severe heat-cycling and high-stress engine loads.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Valve Oil Seal Set\u003c\/li\u003e\n  \u003cli\u003e2 Head Gaskets\u003c\/li\u003e\n  \u003cli\u003e2 Valve Cover Gaskets\u003c\/li\u003e\n  \u003cli\u003e2 Intake Manifold Gaskets\u003c\/li\u003e\n  \u003cli\u003e4 Exhaust Manifold Gaskets\u003c\/li\u003e\n  \u003cli\u003e1 Oil Pan Gasket\u003c\/li\u003e\n  \u003cli\u003e1 Crankshaft Rear Oil Seal\u003c\/li\u003e\n  \u003cli\u003e2 Crankshaft Front Oil Seals\u003c\/li\u003e\n  \u003cli\u003e1 Oil Filter Gasket\u003c\/li\u003e\n  \u003cli\u003e2 Water Outlet Gaskets\u003c\/li\u003e\n  \u003cli\u003eOther small gaskets and seals\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: solid font-size: min-width:\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;\"\u003e2007-2014 Ford Expedition\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;\"\u003e5.4L Triton 3V SOHC \/ U324\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;\"\u003e310 hp \/ 365 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\u003e2007-2014 Ford Expedition (5.4L SOHC 24V Triton V8)\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 U324 Expedition?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2014 Ford Expedition equipped with the \u003cstrong\u003e5.4L Triton 3V SOHC\u003c\/strong\u003e engine; confirm your engine displacement and 24-valve configuration before ordering.\u003c\/p\u003e\n\n\u003ch4\u003eAre new cylinder head bolts required during this installation?\u003c\/h4\u003e\n\u003cp\u003eYes, the 5.4L Triton engine utilizes Torque-to-Yield (TTY) cylinder head bolts which stretch upon initial torquing and cannot be reused.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Towing Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to restore and maintain severe-duty capability, this complete overhaul gasket set ensures the 5.4L Triton V8 delivers reliable sealing under heavy gross vehicle weight ratings and demanding towing conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67547090813176,"sku":"DS-EPX1VVM4W","price":79.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-head-gasket-kit-for-ford-expedition-2007-2014-5-4l-1.jpg?v=1790740369","url":"https:\/\/performancechiptuning.com\/products\/performance-head-gasket-kit-for-ford-expedition-2007-2014-5-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
