This diff cover fits the rear end on Hummer H2, Trailblazer SS, SSR 6 speed, and other Chevy and GMC trucks, vans and SUVs with the 9½ inch 14 bolt rear differential. PML makes three covers for the GM 9½" rear differential and designed this cover for Hummer H2s and similar vehicles that have less space or clearance issues but still want the benefits of an aftermarket cover.
If you do not have an H2 and wish to order this cover, you will need to contact us and let us know what bolt size you have. Please see the Bolt Information section on this page: GM straight fin cover. For the Hummer H2, the stock bolts are metric 8–1.25x21 mm.
PML includes mounting bolts with all differential covers. PML provides bolts that are longer than the stock bolts since the flange on PML's cover is much thicker than stock. The bolts with the stock cover will not work.
GM has used four different bolts on these differentials so to complete your order, we need to know which bolts you have. These differentials have used both metric and standard cover bolts. The bolt length has not been consistent either. When ordering one of these covers, you will need to pull one of your stock bolts out (a top bolt is best) and measure the length and determine whether it is metric or standard.
We know this is a hassle, but we do not want to send the wrong bolts or charge everyone a lot of extra money to cover sending all possible bolts with each cover.
