LML Duramax New 45% Over Injector Set – S&S Diesel LML-45SAC-SET

Unlock more power, cleaner combustion, and smoother performance from your 2011–2016 LML Duramax with the S&S Diesel Motorsport LML-45SAC-SET. This is a complete set of eight brand-new (not remanufactured) injectors engineered to flow 45% over stock.

S&S uses a proprietary nozzle honing process that creates exceptionally clean and consistent orifices for an optimal fuel spray pattern. The result is more complete combustion, stronger power delivery, and improved efficiency compared to worn or unbalanced stock injectors.

Key Features:

• 45% increased nozzle flow over stock
• Brand-new injector bodies and components
• Proprietary SAC nozzle honing for clean, consistent spray holes
• Nozzles flow-matched to within 1% variance per set (tested to OE standards with Viscor SAE-J967 fluid at 40°C / 100 bar)
• Complete injectors flow-matched to within 3% variance
• Injection rate shapes aligned across four pressure/energizing points for balanced cylinder-to-cylinder fueling
• Custom internal build specifications (including piezo modifications) matched to each nozzle’s flow rate

Fitment: 2011–2016 Chevrolet Silverado 2500HD / 3500HD and GMC Sierra 2500HD / 3500HD with 6.6L Duramax LML
