3.0L Duramax LM2 EGR Delete Kit | 2020–2024 Chevy GMC

Dyno Diesels EGR Delete Kit

GM 3.0L Duramax LM2 | 2020–2024 Sierra & Silverado (Limited Models)
Cleaner Airflow. Reduced Heat. Engineered Reliability.

The Dyno Diesels EGR Delete Kit for the 3.0L Duramax LM2 is engineered to remove the factory EGR cooler, EGR valve, exhaust valve, and EGR cooler pipe, eliminating a major source of heat, restriction, and carbon buildup in the intake system.

This kit has been recently updated with improved sealing components, including new gaskets, O-rings, and an upgraded aluminum intake plug, ensuring long-term durability and leak-free operation in high-heat diesel environments.

Why Delete the EGR on the 3.0L LM2?

On the LM2 Duramax, the EGR system recirculates hot exhaust gases back into the intake stream. Over time, this can:

• Increase intake air temperatures
• Introduce soot and carbon into the intake tract
• Reduce combustion efficiency
• Contribute to drivability and long-term reliability issues

Removing the EGR system allows the engine to operate on cooler, cleaner intake air, supporting more consistent airflow, improved combustion stability, and reduced thermal stress—especially important for off-road and performance-oriented builds.

What This Kit Removes

• EGR cooler
• EGR valve
• Exhaust valve
• EGR cooler pipe

By fully eliminating these components, the intake and exhaust paths are simplified and freed from unnecessary restriction.

Kit Includes

• High-quality 4-ply silicone coolant hose (1x)
• Coolant caps (2x)
• Ground cable (1x)
• CNC blocker plates for EGR valve and EGR cooler (2x)
• Aluminum intake plug (1x) (updated design)
• EGR gaskets (2x)
• Updated O-rings for proper sealing

All components are selected to withstand heat, pressure, and vibration typical of modern diesel engine operation.

Performance & Reliability Benefits

• Cleaner intake and charge-air system
• Reduced intake air temperatures
• Improved airflow consistency
• Reduced carbon buildup
• Enhanced long-term engine reliability

Results depend on tuning, driving conditions, and supporting modifications.

Vehicle Fitment

• 2020–2024 Chevy Silverado 3.0L Duramax LM2 (Limited)
• 2020–2024 GMC Sierra 3.0L Duramax LM2 (Limited)

This kit is designed specifically for LM2 engines and is not intended for other Duramax variants.

Installation Notes

• Professional installation is strongly recommended
• Removal of factory EGR components requires partial engine-bay disassembly
• Aftermarket tuning is required after EGR removal

Compliance Notice
