Volume: 0.6 quarts over stock, approximately

PML designed this rear differential cover for 2014 to 2018 Chevy Silverado and GMC Sierra 1500 trucks and SUVs. Some 2019 models may also be able to use this cover.

Benefits:
Heavy duty construction
Extra capacity
Fins for cooling
Drain hole and magnetic drain plug included
New mounting bolts included
Works without spacer with Duragrip and similar aftermarket carriers when changing to 4.10 or deeper gears
Applications:

Cover works without spacer with Duragrip and similar aftermarket carriers, which are required when changing to 4.10 or deeper gears, see Installations below.
Bracket for parking brake cable probably needs to be slightly moved or bent.
Trucks with the V8 engine probably have the 9.5 ring gear and the optional tow package includes the 9.76 ring gear differential. These two differentials seem to have the same cover.
2014 to 2018 Suburbans and Tahoes may have a sway bar behind the stock cover. See the 2015 Tahoe 5.3 Installation below.
2014 to 2018 Cadillac Escalade may be able to use this cover.
Some trucks have the 10 bolt cover (see our GM 10 Bolt Cover).
We have had installations on 2014 to 2018 trucks.

2019 and newer models: May use a similar 12 bolt rear cover that is slightly larger and not compatible with this cover. The GM part number for the gasket for this differential is 22943110. If you have a 2019 and newer with a different OEM gasket part number, see PML Part Number 11172.
