2019-2026 Chevy / GMC LM2 3.0L | Premium CNC EGR Delete Kit

2019–2026 GM 3.0L Duramax LM2 EGR Cooler Removal Kit

Clean up your off-road LM2 engine bay with a complete, purpose-built solution for removing the factory EGR cooler and related components.

This kit is designed specifically for the 3.0L Duramax LM2 platform and includes the essential block-off components, coolant hardware, gaskets, and fittings required for a clean installation.

Removing the factory EGR cooler and valve eliminates several restrictive and failure-prone components from the exhaust gas recirculation system. It also helps reduce the amount of exhaust soot entering the intake system in properly configured competition and off-road applications.

Kit Includes (As pictured)

• High-quality four-ply silicone coolant hose

• Two coolant caps

• Replacement ground cable

• Two EGR valve and cooler block-off plates

• Machined aluminum intake plug

• Two EGR gaskets

• Required installation hardware

Additional Parts Required

This EGR kit is not a complete emissions-system removal package.

A compatible 3.0L LM2 race pipe and custom off-road ECM tuning are required for proper operation.

The following items are not included unless specifically selected or purchased separately:

• LM2 race pipe or turbo-back exhaust system

• ECM tuning and tuning device
  

• CAN bus plugs and additional electrical components

• Professional installation labor

Installation

Professional installation is strongly recommended.

Removal of the factory LM2 EGR system requires access to tightly packaged engine-bay components, draining and rerouting coolant connections, and modifying the truck’s off-road exhaust configuration.

Do not attempt to start or operate the vehicle after installing the hardware until the correct supporting exhaust components and compatible custom tuning have been installed.

Important Fitment Information

This kit is intended for 2020–2022 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 3.0L LM2 Duramax engine.

Fitment is determined by engine code and emissions configuration, not registration year alone.

This kit does not fit the newer 3.0L Duramax LZ0 engine. Confirm that your vehicle is equipped with the LM2 engine before ordering.
