Dynomite Diesel LML-75 75HP Injectors (30% Over) for 2011-2016 LML Duramax

Unlock noticeable power and torque from your 2011-2016 6.6L LML Duramax with the Dynomite Diesel LML-75 injector set. These 30% over injectors deliver approximately 75 additional rear-wheel horsepower, giving your truck stronger throttle response, improved pulling power, and better overall performance while remaining a practical upgrade for many street and light-duty applications.

Each set is precision-balanced and flow-matched so all eight injectors deliver fuel evenly for smooth operation and consistent cylinder-to-cylinder performance. Dynomite Diesel builds these with high-quality components (remanufactured versions feature new internal parts) and SAC-style nozzles designed for improved atomization, cleaner combustion, and efficient fuel delivery at the same rail pressure.

Key Features

• 30% over stock flow for roughly +75 RWHP
• Capable of supporting up to ~625 RWHP with proper supporting modifications
• Balanced and matched set of 8 injectors
• SAC-style nozzles for better atomization and reduced turbulence
• Custom tuning recommended for optimal drivability, performance, and fuel economy (not mandatory)
• Manufactured/remanufactured by Dynomite Diesel in Idaho, USA

Fitment

2011–2016 Chevrolet Silverado 2500HD / 3500HD and GMC Sierra 2500HD / 3500HD equipped with the 6.6L LML Duramax diesel engine.

Important Notes

Custom tuning is recommended for the best results. These injectors are not recommended for frequent heavy towing unless the truck is equipped with larger-than-stock turbo(s); the milder 20% over (LML-50) option is generally preferred for heavy towing on a stock turbo.

Upgrade your LML Duramax with a proven Dynomite Diesel injector set engineered for reliable performance and increased power.
