Prince,

In addition to what Netman posted, the actual gearing your run will depend largely on several factors, such as how you drive your truck (bash vs race vs speed runs), what hop-ups you have, what tires you have etc.. I can guide you in the right direction based on your needs when you actually get a system. If you need further help selecting the system that is right for you, I can guide you there as well.
