FYI the 18 GT PP 10 speed 3.55 Torsen diff is in an iron housing.The 2018 Mustang offers a 3.55 Torsen differential with the EcoBoost PP (unsure if transmission dependent) and also with the GT PP (only with 10-speed auto).

Even if the aluminum housing might be strong “enough” it doesn’t hurt to overkill the build quality/durability.FYI the 18 GT PP 10 speed 3.55 Torsen diff is in an iron housing.
