Speedo gear size
Just installed the C4 and my current speedo gear is white, I am about 10 MPH over actual. Does anybody know what color gear for correct speedo readings? 373 gear

RE: Speedo gear size
there isn't one, ford only makes a 21t, and what you have is a jeep 23t
you got what you got, find someone who works on police cars and have them do a calibration box if you want it fixed. since it's a c4, you can tear it apart and put a 6t output shaft in it. then you 'd need about a 19t driven gear and be right on
