1988 Chevrolet C1500 Cheyenne 5.7L Speedo Inaccurate
Posted to GM Electrical on 7/10/2001 14 Replies

I have this truck that the customer changed rear gear ratio from 3:08 to 3:73 for towing. Of course now the speedo is off. What has to be done to get the electric speedo to read correctly with this gear in rear? Thanks in advance for the help!
