Status: PML has designed and is making protype covers for a rear differential cover for 2019 and 2020 Silverado and Sierra 1500 trucks.
Some 2019 trucks have this new differential and some have the same differential as the 2014 to 2018 trucks.
The 12 bolt rear differential cover on 2014 to 2018/2019 vehicles looks similar but is slightly smaller and the area around the fill hole is slightly different. Scroll down for pictures of the stock covers.
We have heard that the ring gear is about 9.5 and this new differential is made by GM, not American Axle (AAM).
We are collecting information and welcome suggestions and pictures. Email info and pictures of the stock cover to: yourcovers@pmli.com
