Include paper instructions with the delete kit. And then sending all the parts needed to install it would be great! I know it is a cheaper kit but let people know there is some stuff they will need to supply!
Overview
This LML EGR cooler delete kit is designed for 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L Duramax LML engine. It removes the factory EGR cooler and related components that commonly clog with soot or fail over time. By eliminating exhaust recirculation, this LML Duramax EGR delete kit helps improve exhaust flow, reduce intake contamination and simplify the engine system for off-road performance builds.
If you plan to remove multiple emissions systems at once, consider upgrading to the 6.6L Duramax LML Complete Delete Kit, which provides the complete solution for deleting EGR, DPF and other related components in a single package.

Performance Benefits
- Reduces Soot Buildup - Prevents exhaust gases from re-entering the intake, helping keep intake runners and sensors cleaner.
- Improves Exhaust Flow - Removing the EGR cooler reduces restriction in the exhaust path, supporting more consistent turbo operation.
- Eliminates Common Failure Points - Factory Duramax LML EGR coolers and valves often clog or leak; removing them helps improve long-term reliability.
- Supports Tuned Applications - Frequently used with tuned off-road setups where emissions systems are removed.
- Simplifies Maintenance - Fewer emissions components under the hood means fewer potential failure points on high-mileage trucks.
Installation Notes
Installation typically takes 6-8 hours using standard hand tools. The intake manifold does not need to be removed for most installs. ECM tuning is required before installation to prevent diagnostic codes and ensure proper engine operation. Professional installation is recommended if tuning is not already configured.
Frequently Asked Questions
Will this kit fit Cab & Chassis Duramax trucks?
No. This kit only fits 2011-2016 Silverado and Sierra 2500HD/3500HD pickup trucks. It does not fit Cab & Chassis models.
Do I need tuning before installing this LML EGR delete kit?
Yes. ECM tuning is required before removing emissions components. Without tuning, the truck will trigger diagnostic codes and may enter reduced power mode.
Does this kit remove the entire EGR system?
Yes. It deletes the EGR cooler and associated components that route exhaust gases back into the intake system.
What problems does an LML EGR delete fix?
The factory EGR cooler can clog with soot or develop leaks over time. Removing the system eliminates those failure points and stops exhaust soot from entering the intake.
Is everything needed for installation included?
Yes. The kit includes the required block-off components, gaskets and mounting hardware needed for installation.
