In Reply to: What's "K 3.46" in the differential? posted by giltor on September 29, 2001 at 16:31:34:
On US cars, the tag would read as "S3.46" if it was a limited-slip differential. If it is not LSD, it just shows the number without a letter prefix.
What is the German word for limited-slip? Perhaps that's what the "K" denotes. Just a guess.
