LML EGR Delete Kit Highlights
Both kits listed above are for 2011-2016 trucks and rated Hard for installation. Compare finish and price, then confirm fitment on the product page.
LML Duramax tuner: The matching calibration the ECM needs once the EGR hardware is gone.
What the LML EGR Delete Kit Fits and Includes
These kits fit 2011-2016 Silverado and Sierra 2500HD and 3500HD pickups with the 6.6L LML Duramax. The LMM (2007.5-2010) and L5P (2017-2023) use different hardware, so match your engine code before you order.
A complete LML EGR kit should give you:
- EGR valve block-off hardware
- Cooler delete parts and coolant bypass hardware
- Gaskets and mounting hardware Check each product page for the exact parts list. The kit does not include a tune. The ECM monitors EGR flow, and hardware without a matching calibration sets codes and can reduce power.
Installation is rated Hard and involves draining and refilling the cooling system, so choose professional installation if that work is new to you. Each kit includes a model-specific guide, and every product page has an Installation Guide tab.

Most orders are processed the same or next business day, excluding Sundays, and most packages arrive within 3 to 5 business days after leaving our U.S. warehouse. Free shipping applies within the continental United States. Authorized returns are accepted within 45 calendar days of receipt on unused, uninstalled parts in original condition.
Complete Your LML Setup
An EGR delete does not touch the DPF or DEF systems. For all-in-one packages, browse the LML delete kit collection, or the LML Duramax delete pipe options if you only need exhaust. The downpipe connection changed during 2015, so check your truck before ordering. If you are not sure the EGR cooler is the cause, have it pressure tested before you order.

FAQ
Do I need a tuner with an LML EGR delete kit?
Yes. The ECM monitors EGR position and flow, so the hardware and the tune go together. LML tuning flashes through the OBD-II port and does not require an ECM unlock.
Will this kit fit a Cab & Chassis truck?
No. These kits are listed for Silverado and Sierra 2500HD and 3500HD pickups, not Cab & Chassis commercial-style trucks.
Do I need a DPF delete with the EGR kit?
No. The EGR kit covers the EGR valve and cooler only. If you want EGR, DPF, and DEF hardware together, choose an all-in-one LML delete kit.
Can I install it myself?
The installation is rated Hard. Allow a full day, use a lift or rated jack stands, and let the truck cool completely before opening the cooling system.
Off-Road Use Disclaimer
EGR delete kits are intended for off-road, race, or non-public-road use where permitted. They are not intended for use on emissions-controlled vehicles on public roads unless legally permitted. You are responsible for confirming federal, state, and local law before purchase and installation.
