Machined from 6061-T6 aluminum, the cap resists cracking during installation and removal, and the included stainless steel drain plug stands up to rust better than standard aluminum screws. It replaces OE part number 134001 for many 2017–2020 Duramax-powered trucks and certain Cruze engines.\u003c\/p\u003e\n\n\u003ch3\u003eWill this housing cap fit my Duramax 6.6L L5P truck?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the iFJF 134001 cap is engineered to match the factory dimensions and mounting points for GM Duramax 6.6L L5P applications listed by the manufacturer.
