Whether you're hauling gear, towing your trailer, or just cruising, this injector is designed to deliver factory-level performance you can count on. The kit includes new o-rings and a copper crush washer to ensure a tight seal and leak-free install. With a fully refundable core charge and a one-year unlimited mileage warranty, it’s a solid investment in your truck’s future. \u003c\/p\u003e \n\n\u003ch4\u003e Precision Calibrated And Purpose Built For Duramax Engines \u003c\/h4\u003e \n\n\u003cp\u003eThe Industrial Injection 0986435504SE-IIS remanufactured injector is designed specifically for the 2004.5–2005 GM 6.6L Duramax LLY platform, offering a high-quality solution that meets or exceeds factory performance standards. Each injector starts life as a genuine OEM core, but is fully rebuilt using all new OEM internal components, including the nozzle, to ensure optimal spray pattern, fuel delivery, and long-term durability. Every unit is balanced to tighter tolerances than the original manufacturer specs, which results in more consistent fuel flow across all cylinders, smoother idle, and improved combustion efficiency. The included copper crush washer and o-rings simplify installation and help eliminate fuel leaks at the injector seat. This injector is ideal for drivers looking to maintain stock reliability or support mild performance upgrades without sacrificing drivability. It is individually tested on industry-leading equipment to verify resistance, back leak rates, and delivery across multiple load conditions. With a 45-day refundable core policy and coverage under a one-year unlimited mileage warranty, it delivers confidence along with consistent performance. \u003c\/p\u003e \n\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e 2004, 2005 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax LLY \u003c\/p\u003e \n\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n  \u003cli\u003eFits 2004.5-2005 GM 6.6L Duramax LLY engines only\u003c\/li\u003e\n  \u003cli\u003eBuilt from genuine OEM injector cores\u003c\/li\u003e\n  \u003cli\u003eAll internal components are brand new OEM parts\u003c\/li\u003e\n  \u003cli\u003eInjector nozzles are replaced during remanufacturing\u003c\/li\u003e\n  \u003cli\u003eBalanced tighter than original manufacturer tolerances\u003c\/li\u003e\n  \u003cli\u003eTested in-house on state-of-the-art equipment\u003c\/li\u003e\n  \u003cli\u003eEach injector is sold individually\u003c\/li\u003e\n  \u003cli\u003eIncludes new copper crush washer and o-rings\u003c\/li\u003e\n  \u003cli\u003eDirect fit with no tuning or calibration needed\u003c\/li\u003e\n  \u003cli\u003eBacked by a 1-year unlimited mileage warranty\u003c\/li\u003e\n  \u003cli\u003e$150 refundable core charge with 45-day return window\u003c\/li\u003e\n  \u003cli\u003eIdeal for stock or mild performance applications\u003c\/li\u003e\n\u003c\/ul\u003e ","brand":"Industrial Injection","offers":[{"title":"Default Title","offer_id":68032291504401,"sku":"IIS-0986435504SE-IIS-","price":271.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/4133_001.jpg?v=1794464587","url":"https:\/\/gautoparts.com\/products\/industrial-injection-0986435504se-iis-stock-reman-injector-04-5-05-lly-duramax","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
