What configuration level does this kit belong to?

This product belongs to the mid-level configuration category. It is more complete than a basic single-function delete part, but it does not include the added throttle-valve-related coverage found in higher-level configurations.

Is this kit designed specifically for the LBZ engine?

Who is this kit best suited for?

It is best suited for buyers who want a more complete cooler-side delete package than an entry-level option, but who do not need a higher-tier combined delete configuration.

Will the brackets fit the factory bolt holes?

Yes. The brackets are designed around the original cooler layout, providing structural stability for the remaining engine components after the delete.

How should I choose between this kit and other Duramax delete options?

Choose this version if you need a mid-level EGR valve and cooler delete kit for an LBZ application. If you only need a simpler single-function part, a lower-tier option may be enough. If you want broader multi-section coverage, a higher-level configuration may be more suitable.
