Description
Description
The Dieselr Signature L5P EGR Upgrade Kit is manufactured in the USA (with select globally sourced components) and built for clean installs, repeatable sealing, and long-term durability on GM’s 2017–2026 6.6L Duramax (L5P). Precision CNC-machined 6061-T6 aluminum and 304 stainless components deliver an OEM-grade fit without the clutter.
Block-off plates feature a black anodized billet finish with laser-engraved DIESELR logos, paired with machined-finish plates where required for a clean, leak-free install. Across the lineup, we use the same proven manufacturing approach: billet where tolerances matter, stainless where heat and corrosion demand it, and a reinforced high-temp silicone coolant reroute with quality fittings.
✅ What’s Included in the Dieselr Signature L5P EGR Upgrade Kit
- Block-off plates — black-anodized, laser-engraved, billet machined for a clean factory-style fit
- Coolant reroute — 3-ply mesh-reinforced high-temp silicone hoses with brass/6061-T6 Aluminum adapters and clamps
- Sealing — stainless gaskets and automotive-grade O-rings matched to the application (Includes Turbo Gasket for 23-26)
- Hardware pack — stainless/treated fasteners, plugs, clamps, and install extras for a secure finish
Important Notes:
- Manufactured in the USA (with select globally sourced components)
- Professional installation recommended
- For off-road/competition use only where permitted by law
- Designed specifically for 2017–2026 GM L5P Duramax 6.6L
