DIESELR EGR Upgrade Kit (2020-2026 Duramax 6.6L L5P)

The Dieselr EGR Upgrade Kit (2020–2026 Duramax 6.6L L5P) is engineered for reliability, clean routing, and long-term strength. Built from high-grade stainless and reinforced hardware, this system refines exhaust gas circulation for consistent performance in demanding off-road conditions.

Each kit includes CNC-machined block-off plates, gaskets, and high-temperature fasteners designed to handle the pressure and heat of the L5P platform. The upgraded design improves flow balance and eliminates weak points common in factory systems—ideal for tuned or competition setups that need lasting performance under load.

Installation is straightforward with precision-fit components and clear alignment points that ensure a factory-grade seal. The end result: cleaner operation, lower maintenance, and a durable setup that looks as good as it performs.
