This differential cover fits the rear differential Hummer H2, GM 1500HD, C/K 1500 and 2500 with the semi-floating 14 bolt rear axle.

We have several of these GM diff covers on special in as-cast and polish finishes.

Specials #62 and #65-#67 have a bolt hole drilled in the wrong location for these applications. A new hole was manually drilled in approximately the correct location. Note: The hole location is approximate and you may have to file the hole for a correct fit. Although there is an extra hole on the flange, this will not cause any leaking.

Specials #65, #66, #67 (all the as-cast parts) have a boss on top for fill. The polished part (#62) has a combination fill/level check hole.

The current PML part is part number 10303-2.   Click here for that part. The as-cast parts on special are from an older version of this cover and these older versions have top fill holes. Newer versions of this cover do not have the top fill hole as the top boss caused interference with some Dodge applications using this cover on front differentials. (PML now offers a front diff cover specifically for that Dodge application.)

These parts fit and function correctly. They are sold as-is and cannot be returned.

Volume: 0.5 qt. over stock

Prices: $100 for as-cast, $150 for polish finish. Please call to order.

Specials #65-#67, As-Cast Finish

Specials 65-67 are all similar.  Each has a machined boss for oil fill, level check and drain and an un-machined boss that can be used for a temperature sensor.

Special #67 has some discoloration in the casting. Click here for a picture of it.

Special #62, Polish Finish

Special #62 has some light porosity.

This polish finish part does NOT have a top boss. It has a machined boss for oil fill/level check on the side, a drain hole at the bottom, and an un-machined boss that can be used for a temperature sensor.
