DDP LBZ-STK Remanufactured Fuel Injector

Restore factory performance, drivability, and fuel efficiency to your 2006–2007 6.6L Duramax LBZ with the Dynomite Diesel (DDP) LBZ-STK remanufactured fuel injector. This stock-horsepower replacement is built as a direct-fit solution for worn, leaking, or failing injectors.

Every injector is remanufactured using all-new OE internal components and the latest revisions. The result is a high-quality, reliable injector that delivers OEM-level fuel delivery, spray pattern, and response without the premium price of a brand-new unit.

Sold individually, the LBZ-STK is a practical choice when replacing one or more injectors. It is designed for stock and mildly modified trucks used for daily driving and towing. No custom tuning is required when used as a stock replacement.
