DIESELR EGR Upgrade Kit (2017-2019 Duramax 6.6L L5P)

The EGR Upgrade Kit (2017–2019 Duramax L5P) from DIESELR is engineered for Duramax owners who demand long-term reliability, cleaner airflow, and consistent power under load. Built for 2017–2019 GMC Sierra and Chevrolet Silverado 2500/3500/4500/5500 HD trucks, this kit replaces the factory EGR system with high-quality components that eliminate common failure points.

By removing restrictive EGR parts, this kit helps reduce soot buildup, lower exhaust gas temperatures (EGTs), and prevent coolant leaks from the stock EGR cooler. The result is a cleaner, more efficient intake path and better throttle response—especially under heavy towing or work conditions.

Each EGR Upgrade Kit (2017–2019 Duramax L5P) includes precision-fit hardware, gaskets, and corrosion-resistant components for a leak-free, secure installation. Designed to handle the high-heat, high-vibration environment of a diesel engine, it’s built to perform in the toughest conditions.

Ideal for off-road and competition builds, this kit should be paired with custom emissions-off tuning for full functionality.
