You can just swap out the speedo gear. I still need to do mine cuz it's off by about 3-4 mph, and it is messing up my odometer, etc. Here is a quick write-up.

how much do you think it is off

According to this http://www.explorerforum.com/forums/showthread.php?t=112696&highlight=ultra+wheels , if your speedo says 45, then you are really going about 52.

You have to replace the speedo gear with another one with the proper ratio.

Site SEARCHing is fun, try it out.

You could also try a search on the RangerStation. They have a good 'chart' that lists the speedo gear drives by color and teeth.

print the chart out and put tape it on your dash
