Repeated heat cycles cause unequal thermal expansion between the cast-iron cylinder block and aluminum cylinder heads, eroding the OEM elastomeric coating. Over time, this leads to coolant migration into combustion chambers, exterior coolant weepage, and degraded compression across adjacent cylinders under sustained towing or high-operating-temperature conditions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive overhaul kit centers on Multi-Layer Steel (MLS) cylinder head gaskets engineered to withstand extreme cylinder pressures and thermal movement. Constructed with high-tensile spring steel layers coated in high-temperature fluoroelastomer, the gaskets accommodate deck deflection without blowing out combustion fire rings. The kit bundles high-grade Viton valve stem seals, silicone-beaded intake gaskets, and an upgraded perimeter oil pan seal to permanently eliminate vacuum leaks and lower-end oil seepage on high-mileage Gen III V8 blocks.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 Multi-Layer Steel (MLS) Head Gaskets\u003c\/li\u003e\n  \u003cli\u003e1 Rear Crankshaft Gasket Seal\u003c\/li\u003e\n  \u003cli\u003e1 Engine Oil Pan Gasket\u003c\/li\u003e\n  \u003cli\u003e1 Valley Cover Gasket\u003c\/li\u003e\n  \u003cli\u003eIntake Manifold Gaskets\u003c\/li\u003e\n  \u003cli\u003eExhaust Manifold Gaskets\u003c\/li\u003e\n  \u003cli\u003eKnock Sensor Grommets\u003c\/li\u003e\n  \u003cli\u003eDamping Plug Heads\u003c\/li\u003e\n  \u003cli\u003eValve Stem Seals\u003c\/li\u003e\n  \u003cli\u003eFiber Base Plates\u003c\/li\u003e\n  \u003cli\u003eAssorted O-rings and Secondary Gaskets\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;\"\u003e2004-2005 Cadillac Escalade\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;\"\u003e5.3L LM7 Vortec V8 \/ GMT800\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;\"\u003e295 hp \/ 335 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;\"\u003eCS9284, HS26191PT, HS26190PT-2, HS26191PT-1, HGS3168, ES72220, GS33449, HSGM10448L, LGS3165, MIS16340\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\u003e2004 Cadillac Escalade 5.3L V8 (RWD)\u003c\/li\u003e\n  \u003cli\u003e2005 Cadillac Escalade 5.3L V8 (RWD)\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 GMT800 Escalade?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2005 Cadillac Escalade equipped with the \u003cstrong\u003e5.3L LM7\u003c\/strong\u003e engine; verify your 8th VIN digit as this kit does not fit 6.0L LQ9 or 6.2L configurations, and piston rings are not included.\u003c\/p\u003e\n\n\u003ch4\u003eAre new cylinder head bolts required during installation?\u003c\/h4\u003e\n\u003cp\u003eYes, GM Gen III engines utilize torque-to-yield (TTY) cylinder head fasteners that permanently stretch during original assembly and must be discarded and replaced with new bolts.\u003c\/p\u003e\n\n\u003ch3\u003eThe Cadillac Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe duty cycles, continuous highway trailering, and intense engine bay temperatures, this full overhaul kit ensures your \u003cstrong\u003eGMT800\u003c\/strong\u003e platform maintains peak cylinder compression and uncompromising fluid separation across hundreds of thousands of miles.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551502303480,"sku":"DS-EKY4UJRCD","price":89.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-head-gasket-kit-for-cadillac-escalade-2004-2005-5-3l-1.jpg?v=1790797810","url":"https:\/\/performancechiptuning.com\/products\/performance-head-gasket-kit-for-cadillac-escalade-2004-2005-5-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
