Anyone have a ZL1 rear diffuser for sale or knows the part number? Has a 2016 2SS and looking to replace the rear diffuser with the zl1's.

The part number you're looking for is 84306917, but I suggest that you consider this aftermarket diffuser from next gen speed that I chose, it looks much more aggressive. C7 Carbon also has worthy alternatives, although those are more expensive.

Not to revive a dinosaur thread here... but there seems to be little information on this. I'm looking to potentially replace my rear valance/diffuser, but does it come painted or unpainted? It doesn't seem to specify anywhere. I know most body panels come unpainted, but I was hoping this is a different case lol.

This is indeed the part number 84306917.

Honestly, I'm not sure whether or not this piece comes painted. Body parts that do typically either have a separate variant (and part number) for each color or at least specify the color in the description.

I still recommend the aftermarket part I mentioned above, since it looks a million times better, unless you specifically want the ZL1 style overhang behind the rear tires.

I believe it comes only unpainted, from what the dealer said. The majority of aftermarket diffusers I really don’t care for..especially the ones that look like they are part of a body kit. 🤮

Yours actually looks decent though. It’s different from stock, but not TOO different.

Yup, that's exactly what I'm talking about. It's a variation of the stock diffuser with the extra fins that might actually have at least a minimal aero effect, too. Not even a tinge of "ricerness".
