Status: PML designed and manufactured some prototype rear differential covers for 2019 and newer Silverado and Sierra 1500 trucks and GM 1/2 ton SUVs and vans. We are collecting information and welcome suggestions and pictures. Email us at: email@example.com
Some 2019 trucks and SUVs 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. See SPECIFICATIONS section.
We have heard that the ring gear is 9.5 or 9.75 and this new differential is made by GM, not American Axle (AAM).
