The Mahle HS55522 Top End Gasket Set is built specifically for 2017-2023 GM Silverado and Sierra HD trucks equipped with the 6.6L Duramax L5P engine, giving you the confidence that every gasket and seal is designed to fit correctly the first time. This kit includes the major sealing components needed for cylinder head repairs and upper engine service, helping eliminate the frustration of chasing down individual parts during a rebuild. Additionally, Mahle has earned a strong reputation for producing OE-quality sealing components trusted by professional engine builders and diesel technicians alike. That quality becomes especially important when your truck is relied on for towing, hauling, or long-distance driving where reliability matters most. Instead of gambling on incomplete kits or questionable fitment, this set gives you the coverage needed to properly reseal your engine with confidence. When you are already investing the time and labor into an L5P repair, using a complete Mahle gasket set simply makes sense.\u003c\/p\u003e\n\u003ch4\u003eEngineered To Handle Demanding Duramax Repairs\u003c\/h4\u003e\n\u003cp\u003eThe Mahle HS55522 gasket set was designed to support comprehensive upper engine repairs on the 6.6L Duramax L5P platform found in 2017-2023 GM HD trucks. Inside the kit, you will find cylinder head gaskets along with intake manifold gaskets, exhaust manifold gaskets, valve cover gaskets, and additional upper engine seals required during top-end service. Each component is manufactured to OE specifications to help ensure proper alignment, sealing performance, and long-term durability under diesel operating conditions. What's more, using matched sealing components throughout the repair helps maintain consistent sealing pressure across critical engine surfaces. This becomes especially important in high-compression diesel engines where heat, combustion pressure, and vibration can quickly expose weak sealing materials. Mahle designs these gaskets to help maintain coolant integrity, combustion sealing, and oil control throughout the upper engine assembly. For technicians and Duramax owners looking to complete a reliable head gasket replacement or upper engine rebuild, this kit provides the complete sealing solution needed to get the job done properly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2017, 2018, 2019, 2020, 2021, 2022, 2023 GM Sierra\/Silverado 2500HD\/3500HD 6.6L Duramax L5P\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConfirm fitment for 2017-2023 L5P engines\u003c\/li\u003e\n\u003cli\u003eDesigned for 6.6L Duramax applications only\u003c\/li\u003e\n\u003cli\u003eIncludes gaskets for top-end engine service\u003c\/li\u003e\n\u003cli\u003eReview included components before installation\u003c\/li\u003e\n\u003cli\u003eIdeal for head gasket replacement jobs\u003c\/li\u003e\n\u003cli\u003eRecommended for upper engine rebuilds\u003c\/li\u003e\n\u003cli\u003eClean sealing surfaces are required\u003c\/li\u003e\n\u003cli\u003eCheck cylinder heads before reassembly\u003c\/li\u003e\n\u003cli\u003eFollow factory torque specifications carefully\u003c\/li\u003e\n\u003cli\u003eReplace any damaged related hardware\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mahle","offers":[{"title":"Default Title","offer_id":54125180223772,"sku":"MCIHS55522","price":295.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/mahle-hs55522-1.jpg?v=1779121182","url":"https:\/\/www.alligatorperformance.com\/products\/mahle-hs55522","provider":"Alligator Performance","version":"1.0","type":"link"}
