Product Information
Product Description
2019–2022 Chevy / GMC LM2 3.0L Duramax (E46 ECM Only) | Complete Delete Kit
IMPORTANT – READ BEFORE PURCHASE
Compatibility
This product is designed for 3.0L Duramax 1500 pickup trucks only.
It is not compatible with 3.0L Duramax SUVs. SUV models use the E66 ECM, which requires a different product option that is not currently available on the EZ Lynk platform.
This option is also for non-refresh / pre-refresh trucks only, typically covering 2020 through early 2022 model years.
2022.5+ refresh trucks are not supported with this product, as they use the E66 controller.
How To Tell If Your Truck Is a Refresh Model (2022.5+)
One of the easiest ways to identify a refresh truck is by looking at the center radio display:
- Large newer-style center screen = Refresh (2022.5+)
- Older-style center screen = Pre-refresh / non-refresh
For 2022 model year trucks, you can also verify by checking the 12th digit of the VIN:
- 4 or lower = Pre-refresh / non-refresh
- 5 or higher = Refresh (2022.5+)
