C55 rear gear ratio, and compatibility with other differentials.
What does the c55 have for the rear gear ratio? I am looking to go for the e55 rear gear ratio, and also was interested in seeing what differential interchanges with the c55. Does the e55 have the same ring and pinion?

I guess I should ask what differentials exchange with the c55 differential. Looks to be like a w210 unit. I’m looking to go to a 2.65 rear gear and wondering what I can exchange it with,

Yeah, I got that part of your question, but I was answering: "What does the c55 have for the rear gear ratio?" and "Does the e55 have the same ring and pinion?"
If you're talking swapping pumpkins, the W210 E55 has a 2.82 ratio and the housings are not the same. The W211 E55 has the 2.65 rear gear but has a very different housing than the C55. I think you're looking at swapping R&P from a W211 E55 if possible. AFAIK, 2005+ W211 E55's and our C55's both have 215mm ring gears.
Are you aware you need your TCU programmed if you swap R&P?

Yes , I am going to do an M113k swap in the c55 and was probably going to do this at the same time. I wonder if a 2005 or 2006 E55 tcu would do the trick temporarily with the gear swap. I wouldn’t have to mess with the ECU and tcu twice.
thank you for the information BTW
