Factory Precision Rebuilt For Superior Flow And Fit

The Industrial 0986435520SE-IIS Reman Stock Injector is designed to meet the exact specifications of the 2007.5–2010 GM 6.6L Duramax LMM fuel system and is rebuilt with a level of precision that exceeds OEM standards. Starting with a genuine stock injector body, Industrial Injection completely replaces all internal components—including the nozzle, with brand, new OEM parts to ensure long-term reliability and factory-calibrated flow. Each injector is individually tested using advanced diagnostic equipment to validate its performance under multiple operating conditions. This includes a full resistance check, system leak test, purge cycle, and a full spectrum of load tests from idle to high-demand. The balancing process used during remanufacturing results in better fuel atomization and smoother engine operation, making it ideal for stock setups and modified builds alike. The kit includes all installation essentials and is compatible with stock tuning, so you don’t need to flash or recalibrate your ECM. If you're chasing injector-related issues or just want to refresh your truck’s performance, this injector offers a proven, high-quality solution backed by industry-trusted craftsmanship.
