Over extended duty cycles, standard composite gaskets and early-generation elastomeric intake gaskets degrade under repetitive heat-soak. This thermal expansion differential between the cast-iron cylinder block and cast-aluminum cylinder heads causes scrub, resulting in localized fire-ring failure, external coolant weeping into cylinder bores, vacuum loss at the intake manifold runners, and oil pan gasket degradation that drops vital engine oil pressure under heavy towing conditions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive overhaul kit addresses thermal scrub through heavy-duty Multi-Layer Steel (MLS) cylinder head gaskets. Featuring tempered spring steel outer layers coated in high-temperature Viton fluoroelastomer, these gaskets maintain elastic recovery under severe cylinder head lift and peak combustion pressures. The package includes reinforced oil pan gaskets, a durable rear main seal, Viton valve stem seals to prevent guide oil blow-by, and heat-resistant valley cover gaskets that reliably isolate the crankcase valley on direct-fit Gen III pushrod V8 powerplants.\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\u003eOther O-rings and 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: 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;\"\u003e2002-2006 Chevrolet Suburban\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;\"\u003eVortec 5.3L V8 (LM7\/L59) \/ 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;\"\u003e285-295 hp \/ 325-335 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\u003e2002-2006 Chevrolet Suburban 1500 5.3L OHV V8\u003c\/li\u003e\n  \u003cli\u003eCompatible with GM 4.8L and 5.3L OHV V8 engine architectures listed by OEM reference numbers\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 Suburban?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2006 Chevrolet Suburban equipped with the \u003cstrong\u003eVortec 5.3L\u003c\/strong\u003e V8 engine, but note that 8.1L big-block V8 and 6.0L 2500 models are excluded.\u003c\/p\u003e\n\n\u003ch4\u003eAre piston rings and head bolts included in this rebuild kit?\u003c\/h4\u003e\n\u003cp\u003eNo, piston rings and cylinder head bolts are not included and must be sourced separately to complete your engine rebuild.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to match the rigorous demands of full-size GMT800 platforms, this sealing solution guarantees dependable coolant retention and sustained oil pressure during high-load hauling, severe mountain grades, and heavy-payload towing operations.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551497355512,"sku":"DS-EUIFL4NTR","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-chevrolet-suburban-2002-2006-5-3l-1.jpg?v=1790797606","url":"https:\/\/performancechiptuning.com\/de\/products\/performance-head-gasket-kit-for-chevrolet-suburban-2002-2006-5-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
