    PML is designing this differential cover for the front of Cadillac, Chevy and GMC 4WD 1/2 trucks and SUVs. For example, 2020 and newer Silverado and Sierra 1500 trucks would be able to use this cover as well as some Suburban, Tahoe, Yukon and Cadillac Escalade SUVs.

    2019 and older vehicles probably have the GM 8.5 IFS front differential, and there is not a cover for that.

    We are collecting information and welcome suggestions and pictures. Email info and pictures of the stock cover to: [email protected]

    Stock Cover

    There maybe two different front differentials available with different covers. The possible GM AC Delco part numbers are 84544562 and 84428296. The covers look identical. The only noticeable difference is that 84428296 has a magnet on the inside.

    These images show GM AC Delco part number 84428296. The PML preliminary design is based on stock cover part number 84428296. Last picture shows the stock cover on a 2020 Silverado 1500 4WD 5.3.
