LBZ Duramax Injectors

Restore factory reliability, eliminate excessive exhaust smoke, or support your high-horsepower build on your 2006–2007 Chevy Silverado or GMC Sierra 2500HD/3500HD with our comprehensive selection of LBZ Duramax fuel injectors. Over high mileage, the 6.6L LBZ common-rail injectors are susceptible to natural internal wear, leading to poor fuel atomization, balance rate deviations, rough idling, and a noticeable loss of fuel economy. Whether you need a single replacement to fix a misfire, a complete set of genuine OEM stock-flow injectors for a factory rebuild, or upgraded high-flow performance injectors to match a larger turbocharger and aggressive custom tuning, we have the exact fueling solution for your goals. We supply brand-new and premium remanufactured injectors, strictly matched sets of 8, and all necessary installation components from trusted industry leaders like Bosch, S&S Diesel Motorsport, Exergy Performance, and Full Force Diesel.
