Differential Covers, Hummer H1 Front and Rear, 12 Bolt, Black, Powder Coated

Volume: approximately 0.5 quarts over stock

Dimensions: approximately 11.7 tall x 11.8 wide x 3.8 deep

On Hummer H1 the front and rear differentials are the same. This PML cover will fit both axles and works with standard undercarriage protection. It is designed to slide between the brake calipers.

On an H1 with an aftermarket brake kit with larger calipers, one of the calipers had to be loosened to remove the stock covers and install this PML differential cover. After installation, the caliper was retighted. No modifications were needed. We do not know which brake kit so there may be variations.

Always check your vehicle to verify configuration and clearance before ordering.

Benefits

1996 Hummer H1 stock front differential cover

PML designed this differential cover with:

Extra capacity

Fins and sand cast aluminum construction to dissipate heat from the fluid

Clearance for brake calipers and undercarriage protection

Wide gasket flange for a secure seal to the housing

Thick walls to add strength to the differential housing

Bolt on replacement for stock covers

Drain hole with magnetic drain plug included

Bosses that can optionally be machined for a temperature sending unit

H1 differential covers are similar to a standard Dana Spicer AMC Model 20 cover (PML part number 5048). The cover bolt pattern, shape, and fill hole do not match. We've also heard that this is a Torsen differential.
