    GM ACDelco Genuine Duramax Parts

    ACDelco is General Motors' genuine parts brand, supplying the factory-engineered components that Chevrolet and GMC diesel trucks were built with. Unlike aftermarket guesswork, ACDelco parts are built to the exact OEM specification for the Duramax platform � oil filters, glow plugs, gaskets, water pumps, and more. CFM Diesel Performance carries ACDelco only for Duramax applications, so when you need a factory-correct fix instead of a compromise, you're covered.

    Why Duramax Owners Trust ACDelco

    ACDelco is GM's OEM parts division, the same source that supplies components on the assembly line for Chevrolet and GMC trucks — meaning every part is validated to the tolerances the Duramax engine was designed around, not reverse-engineered after the fact.

    For the L5P, LML, LMM, LBZ, LLY, and LB7 Duramax generations, ACDelco covers the everyday-critical parts: oil and fuel filters, glow plugs, water pumps, and gaskets that keep a factory-tight seal.

    CFM Diesel Performance stocks a growing selection of genuine ACDelco parts for Duramax trucks — browse filters, glow plugs, and more below. Can't find the exact ACDelco part number you need? Contact our team and we'll source it for your build.
