Dynomite Diesel LBZ-75NZ 30% Over Injector Nozzle Set | 2006–2007 6.6L Duramax LBZ | +75 HP
Unlock more power from your 2006–2007 6.6L LBZ Duramax with the Dynomite Diesel LBZ-75NZ 30% Over Injector Nozzle Set.
These upgraded nozzles increase fuel flow by 30% over stock and typically deliver around 75 rear-wheel horsepower when paired with proper supporting modifications and professional calibration. They are the largest nozzles recommended for use with a stock CP3 pump and stock turbo, making them a strong choice for street-performance builds that want meaningful gains without immediately stepping up to a larger pump or turbo.
The set is precision-balanced and flow-matched as a complete package so all eight injectors deliver evenly. This supports smoother operation, better atomization, and a cleaner burn compared with worn or mismatched stock nozzles. Many owners also report improved throttle response. Because you are replacing only the nozzles (not the entire injector), this is a cost-effective upgrade when your existing injectors are still in good mechanical condition.
Key highlights
- 30% over stock flow for approximately +75 RWHP
- Supports 675–700 RWHP with the right supporting modifications and tuning
- Largest nozzle size recommended for stock CP3 and stock turbo
- Balanced and matched set for even cylinder-to-cylinder fueling
- Typically includes new copper sealing washers
- Designed for 2006–2007 Chevrolet Silverado and GMC Sierra 2500HD/3500HD with the 6.6L LBZ Duramax
Important installation notes These nozzles must be installed and the injectors properly calibrated by a shop experienced with oversized diesel injectors. Results vary based on the condition of the original injectors, supporting modifications (intake, exhaust, tuning, etc.), and the quality of the calibration. They are not recommended for frequent or heavy towing when the stock turbo is retained.
This nozzle-only upgrade gives serious LBZ owners a proven path to more power and better fueling characteristics while keeping the original injector bodies. Pair them with quality tuning and supporting mods to get the most from your Duramax.
