GM 12 Bolt, Rear Differential Cover
2019 and Newer Silverado, Sierra, SUVs

Project Under Consideration, PML Part Number 11172

PML is looking into an after market cover for the 2019 and newer Chevrolet and GM trucks and SUVs.

The 12 bolt rear differential cover on 2014 to 2018 vehicles looks similar but is slightly smaller.

We have heard that the same ring gear is used, 9.5 or 9.76 inches.
