    Default Z/28 Rear Differential Cover

    Anyone that has a Camaro rear differential and is doing some road racing or AutoX might be interested in the Z/28 rear cover.

    GM added a cooler to the Z/28 diff much like the ZL1 except they built it into the rear cover instead of the case. This make it pretty easy to add a cooler to your car.

    On the Z/28 GM uses the TR6060's fluid pump to pump the transmission fluid from the transmission up to the radiator then back to the differential then to the transmission. If you were to do this on a G8 you would most likely need to switch to all AN lines or just add a separate fluid pump and radiator like I've seen done before by another member.

    22923280 is the GM part number for the cover.

    Fantastic price. Assuming it won't fit a G8 diff, though...

    Default Z/28 Rear Differential Cover

    I thought the ZL1/Z28 diff required the zl1/z28 Camaro cradle? As the diffs are much larger. I may be and probably am wrong. If they fit the regular Camaro diff this is awesome upgrade I might have to consider. As I'm gonna go with a 3.27 gear eventually.

    The ZL1 diff is the larger Iron case. The Z/28 diff is the same is similar to the Camaro SS except with more support ribs on the case.
