LLY Duramax Turbocharger 2004 - Remanufactured Direct-Fit Diesel Replacement

Overview

This is a direct-fit turbocharger for the LLY Duramax diesel (2004). It is professionally remanufactured to OEM specification for a professional-grade repair that restores proper function and reliability to your truck.

What It Does & How It Helps

The turbocharger uses exhaust energy to force more air into the engine, which is what gives a diesel its power and efficiency. When a turbo wears out you get lost power, excess smoke, whining or grinding noises, and often a check-engine light for underboost or overboost. A fresh, correctly-matched unit brings back full boost and clean, strong performance.
