Whether you're chasing smoother power delivery, better fuel economy, or simply trying to get rid of that rough idle, the Industrial 0986435521SE-IIS Reman Stock Injector is built to bring your truck back to life. These aren’t just cleaned up take offs, each injector is completely rebuilt with brand-new OEM parts, including the nozzle, so you’re essentially getting factory-fresh performance without the new-part price. What makes it even better is that these injectors are balanced to tighter tolerances than the originals, helping your engine run cleaner and more efficiently than stock. Some drivers even see up to a 3 MPG boost, which adds up fast if you're doing a lot of driving or towing. With a fully refundable core and a one-year unlimited mile warranty, this upgrade gives you peace of mind along with smoother starts and more responsive throttle. It’s a smart choice whether you’re daily driving, hauling, or pushing a little more power.\u003c\/p\u003e\n\u003ch4\u003eCalibrated With Precision And Tested For Every Load\u003c\/h4\u003e\n\u003cp\u003eThe Industrial 0986435521SE-IIS is not your average remanufactured injector, it’s a complete rebuild performed in-house using OEM stock bodies and all-new factory-grade internals. Every unit undergoes an extensive multi-point test process that simulates real engine conditions, including resistance testing, leak checks, purge cycles, and performance verification at idle, mid-load, and full-load ranges. Each injector is flow-matched and balanced more precisely than the original manufacturer’s standards, which helps ensure consistent fueling across all cylinders and maximizes engine efficiency. The set includes a new copper crush washer and o-rings to ensure a proper seal on installation, which minimizes the chances of leaks or fuel system issues down the line. These injectors are engineered for 2006-2007 GM Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L Duramax LBZ, and they’re designed to drop right in without the need for tuning. Whether you’re maintaining a workhorse or building a competition-ready setup, this injector meets the performance demands without sacrificing durability. Backed by a one-year unlimited mileage warranty and a refundable core, it’s a dependable upgrade from a trusted name in diesel performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e 2006, 2007 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax LBZ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2006-2007 GM 6.6L Duramax LBZ engines only\u003c\/li\u003e\n\u003cli\u003eBuilt from OEM injector bodies with new OEM parts\u003c\/li\u003e\n\u003cli\u003eNozzles, o-rings, and crush washers are all brand new\u003c\/li\u003e\n\u003cli\u003eEach injector is tested on a state-of-the-art bench\u003c\/li\u003e\n\u003cli\u003eTest procedures include idle, mid, and full load simulations\u003c\/li\u003e\n\u003cli\u003eFlow balanced to tighter tolerances than OEM standards\u003c\/li\u003e\n\u003cli\u003eIdeal for both stock and high-performance applications\u003c\/li\u003e\n\u003cli\u003eExpected fuel economy gains range from 1 to 3 MPG\u003c\/li\u003e\n\u003cli\u003eDirect replacement with no tuning required\u003c\/li\u003e\n\u003cli\u003eSold individually for targeted replacement or full sets\u003c\/li\u003e\n\u003cli\u003e$150 core charge refundable if returned within 30 days\u003c\/li\u003e\n\u003cli\u003eCovered by a 1-year unlimited mileage warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Industrial Injection","offers":[{"title":"Default Title","offer_id":68032280428817,"sku":"IIS-0986435521SE-IIS-","price":379.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/4143_001.jpg?v=1794464353","url":"https:\/\/gautoparts.com\/products\/industrial-injection-0986435521se-iis-reman-stock-injector-06-07-gm-6-6l-duramax","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
