I seem to have misplaced my documentation where I ordered the rotors from; however, to get the proper OEM part #, just go to the AC Delco site listed below:

Although my new OEM rotors & OEM brake pads perform great, I would seriously consider ordering for my H2 next time the SP Performance rotors I put onto my 08 Jag XJ & my wife's 04 Jag XJ because my H2 OEM rotors already show corrosion whereas both of the Jag's SP Performance rotors look as clean & shiny as when they came out of the box. The Jaguar's braking performance has been great too.

If interested in the SP Performance rotors for an H2, here is the link for them:

Front: SP Performance T55-056-P | eBay

Front part #: T55-056-P

Rear: SP Performance D55 057 P Diamond Slot Brake Rotors Zinc Plating L R PR Rear | eBay

Rear part #: D55-057-P

By the way, I also installed recently along with the shocks what a lot of folks may over look referred to as Suspension Bumpers. GM charges $33.52 each for the 2 in the front which is about $20 more than online; but, you will not incur approximately $10 for shipping & you will know it's the exact part. GM's part # is: 15835667
