You are correct, the GM images are wrong for showing a black caliper. I have the copper free on my SS 1LE. Same brake components as a copper free ZLE. My GM parts source also shows the 85113991/92 as the part # for my rear calipers.

I noticed this discrepency before looking at AC Delco's site.

To summarize the BCD Copper Free Brake Package calipers, here is a list of all variants of the BCD calipers. SS 1LE (A1Y) (red), ZL1 (grey), ZLE (A1Z) (red), and SS (black). Three different caliper colors depending on the model variant. Only the SS 1LE (A1Y) and ZLE (A1Z) share the same part #s due to both having the 1LE package red calipers. SPECIAL 2024 MODEL VARAINTS ALSO NOTED.

2024 SPECIAL MODELS:
For the 2024 special models, the Garage 56 ZL1 (RPO X56) share the same GRAY calipers as the ZL1 (non-1LE).

The 2024 Collector's Edition ZL1 (RPO Z4B) is a unique RED caliper package BUT with the ZL1 LOGO.

2024 Collector's Edition ZL1 (ZL1 LOGO):

As mentioned previously, ALL BCD COMPONENTS are the same part #s EXCEPT CALIPERS due to color change for variants. ZL1 COLLECTOR EDITION IS RED CALIPER BUT WITH ZL1 LOGO.

Also, while the typical NON-BCD ZL1/ZLE (copper content) brake package that has the Ferodo HP1000 pad carry the RPO code J6H, the J6H RPO is also used on all BCD equipped cars.

85113992 is BLACK with a Camaro label on it all the others came in RED with the 1LE logo called Schram Auto and they had the one I was missing.
