It sounds like your speedomet isn't reading fast enough. To make it read faster you need less teeth on the driven gear. 16 tooth is the smallest they make. It is a standard part. Just pick one up at the local ford dealer. Last I checked, about $3 less then the speedo shop.<br><br>I was running a 16 tooth with 33s, but I had 4.10 gears. (stock was an 18 tooth with the 4.10s) I don't think it will work with 3.50s. You may need a custom speedometer transmission from a speedo shop.<br><br>To stir the pot a little more, I think that there were 2 different DRIVEN gears. A 7 tooth or an 8 tooth. This is not confirmed, but I though I say it someplace once. I have no idea what would be original on what. Any one with a LOT of transfer case experence want to try this one?
