I'm not sure either which size diff we have, but I had 3.73 Richmond's on my 2010 Gen5 and had no problems. Perhaps we can get some feed back and determine if these gears are compatible. I'd also be curious about price... the 3.73's were not as inexpensive as I would have liked, but you get what you pay for.

Anyone know what size differential on the 6th gen SS? Thanks-
