Overview
The LBZ delete kit is designed specifically for late 2006–early 2007 Chevrolet Silverado and GMC Sierra 2500/3500 trucks equipped with the 6.6L LBZ Duramax diesel engine. The kit removes the factory EGR cooler and related components, replacing them with a stainless steel passenger-side up-pipe and high-flow intake tube. By eliminating the restrictive EGR system, this setup helps reduce soot buildup in the intake and supports cleaner airflow through the engine.
