The Garrett GT3794VA Stage 1 AVNT Turbo Kit fits the 2007-2009 Chevy Silverado 2500 with the Duramax 6.6L diesel and delivers a factory-style variable-vane turbo upgrade for stronger boost response.

Install Difficulty: Professional Install Only
Turbocharger replacement requires exhaust and intake disassembly, coolant and oil line service, and typically takes 6-8 hours on a vehicle lift. Professional ECU tuning is required after installation to safely calibrate boost and fueling.

Product Overview

This Stage 1 kit uses Garrett's GT3794VA variable-vane turbocharger, engineered as a direct-fit replacement for the LBZ and LMM Duramax platform.

The AVNT (Advanced Variable Nozzle Turbine) housing improves spool time and exhaust brake performance versus the stock unit.

Ideal for owners chasing more airflow for towing, sled pulls, or a supporting mod for tuning on the 6.6L Duramax.
