I believe you do. Or get an adjustable one, I had a local shop do it for about $40. I got tired of all the miles that were put on, lol cuz it thought I was going 80MPH, :lol:ryanwitski said:thanks! I have a 3.42 so hopefully it won't be that bad, it 5mph fast anyway. If it needs calabrated exactly how do I do that again? Do I have to switch a gear in the speedo or somthing. thanks for the help!

You need to change the drive and/or driven speedo gears within the transmission to match the new rear end ratio:
