FAQ
Is this injector a direct fit for LBZ?Yes. It's built on the correct LBZ architecture and fits 2006-2007 Duramax LLY/LBZ applications. Always verify your VIN/engine code.
Do I need tuning with a Race 6 (38 LPM) injector?Yes. Custom calibration is strongly recommended to manage fueling, smoke, EGTs, and rail pressure at this flow level.
Will stock fuel supply support these?High-flow injectors require adequate low-pressure supply and CP3 capacity. We recommend an upgraded lift pump and an LBZ-based CP3.
Is this a single injector or a set?Sold individually with a refundable core. Order quantity 8 for a complete set. Seals and return line parts are available separately above.
