I did a search but it said key words not found, so here's my issue.

My speedometers is roughly 10 mph off when I do 40 I'm really doing 30. Is there a speedometer gear I can get to try and help this be a little more accurate?

Yep you can get one on line with TCI and they will help you find what works best for what you have. You will need to know gear, wheel, tire and trans. I think you just plug it in and it should tell you, if know call them and they can help.
