2017 - 2026 6.6L Duramax L5P

The L5P Duramax is a strong platform, but it uses different fuel system and engine parts than the older LB7, LLY, LBZ, LMM, and LML trucks. Owners shopping this page are often looking for fuel rails, cylinder heads, fuel filter upgrades, head studs, and injection pump related parts.

L5P engine and fuel system parts, cylinder heads, rails, filters, turbo parts, cooling parts, and drivetrain support for 2017-2026 Chevy and GMC trucks. If the truck is a 2020-2024 short bed and you are looking at fuel filter upgrades, double-check cab and bed fitment before ordering.
