Industrial Injection XR1 Series GT3788 64mm Billet Turbocharger for 2004.5–2010 Chevy/GMC 2500HD/3500HD 6.6L Duramax LLY/LBZ/LMM

This XR1 Series GT3788 64mm Billet Turbocharger is a bolt-in upgrade for the 2004.5–2010 Chevy/GMC 2500HD/3500HD 6.6L Duramax LLY/LBZ/LMM. It uses the factory mounting points, so you get more airflow than the stock turbo without a custom manifold or piping job.

Stepping up the turbo lowers exhaust gas temperatures under load and gives larger injectors or tuning the air they need, which is where a stock turbo usually runs out of breath.

Why we like it

• Billet compressor wheel for more airflow and strength
• Built on a new Garrett/BorgWarner core, not a rebuilt unit
• Helps lower EGTs on tuned trucks
• Factory-style fit with stock mounting points
• Emissions: not CARB exempt. For off-road or competition use only on pollution-controlled vehicles
