I decided to go from 3.55 gear to 4.10 gears. This is my question where do I go to have it done?

 

Do you have a 4x4 or a 4x2?

You should be able to get it done at a local auto shop. I would just call around. There is a local gearing shop near me but I doubt thoes are everywhere. Some auto performance shop should be able to get it done for you.
