Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.

I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.

Dear customer,, you can install other ratios, so there is no problem as long as the teeth are the same and have the same fit at the break, the problem is that you are going to have a difference in performance the smaller the ratio the less power but it will have a greater acceleration accompanied by a slightly higher maximum speed. This is the relation that causes the change.

But if you bought a relationship with the same design and feature you will have no problem installing it.
