For the Hummer H2, see PML diff cover P/N 10303-2.

For 2007 and newer vehicles, if your stock cover has a fill hole, do not order P/N 9504. Order PML diff cover P/N 10303-2. If your stock cover does not have a fill hole, this cover (P/N 9504) will work.

GM applications can also use P/N 10303-2 (click here).

Note: 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.

• Bolt length is measured from the underside of the head (where a washer would sit) to the tip.
• Metric bolts will have 20 threads per inch, standard ones will have 18. Also, a bolt head with lines or letters on it is typically standard. A bolt with numbers such as 5.8, 9.8, 10.9, or 12.9 is likely to be metric.

Please note the length of your stock bolts, and whether they are standard or metric in the vehicle information section when placing your order so we can provide the correct bolts.
