Hi there! I’ve been looking through the forums all day and haven’t found the answer I am looking for. I have a 1997 s10 4.3 v6 with 4x4. I’m trying to figure out how to fix my speedometer. I went from a 235/75r15 to a 235/50r18. How do I go about getting my speedo back to normal? I’ve heard about changing gears in the tail shaft and transfer case, as well as doing it electronically. My dash is all mechanical so I’m assuming I have to mess with the gears right? I also heard that these trucks didn’t come with a speedo gear, instead they have a speed sensor? Let me know what my options are! Thank you!
