DDP Duramax Injectors (DDPNLML-SM) for 2011-2016 Duramax LML

LML 60% Over Injectors for 2011–2016 6.6L Duramax (800+ RWHP)

LML 60% Over Injectors for the 2011–2016 6.6L Duramax deliver the fuel volume serious 800+ RWHP builds demand. If you are running upgraded turbochargers, dual fuelers, or a fully built engine, you need injectors that keep up. These brand new injectors eliminate the hassle of a core charge while giving your setup the fueling capacity required for competitive racing and dyno performance.

Because every high-horsepower build is different, we build each injector set to match your exact modifications and intended use. As a result, you get precise fueling tailored to your truck—not a generic off-the-shelf solution.

Why LML 60% Over Injectors Make Sense for Big Power Builds

Once your LML Duramax crosses into the 800+ RWHP range, factory injectors simply cannot supply enough fuel. Therefore, upgrading to LML 60% Over Injectors becomes essential. These injectors increase fuel flow significantly while maintaining balance and consistency across all eight cylinders.

• Fits 2011–2016 LML Duramax 6.6L

• Supports 800+ horsepower applications

• 60% Over flow rate (larger sizes available)

• SAC style nozzle design

• Brand new units

• No core charge required

• Balanced matched set (race waiver required)

Additionally, we balance each injector set before shipment. This process ensures smooth power delivery and stable fueling under heavy load.

SAC Style Nozzle Design Improves Atomization

These LML 60% Over Injectors feature a SAC style nozzle, which improves fuel atomization at high pressure. Better atomization leads to more efficient combustion. Consequently, your engine runs cleaner and more consistently at elevated boost levels.

However, larger injectors require proper supporting modifications. For best results, pair them with:

• LML Duramax Turbochargers

• LML Duramax Fuel System Upgrades

• LML Duramax Lift Pumps

• LML Duramax CP4 Conversion Kits

When you combine airflow and fuel pressure support with proper tuning, you maximize both reliability and performance.

Built for Competitive Use

If you compete at the track or chase dyno numbers, you already know that downtime costs rounds. Even the highest quality components can experience wear under extreme racing conditions. For that reason, many competitive customers order an additional spare injector to keep on hand.

Should you need service, we process testing and repairs on a first-come, first-served basis. During peak racing season, turnaround times may extend to 2–4 weeks. Therefore, planning ahead can save you from missing valuable seat time.

Contact our sales team if you would like pricing on a spare LML 60% Over Injector.

Lead Time Information

Because we custom build these LML 60% Over Injectors to your specifications, we do not guarantee exact ship dates. Typically, however, we ship within 3–4 weeks after you place your order and complete the injector worksheet.

This build process ensures we match your injectors precisely to your horsepower goals and supporting modifications.
