do i need a bearing install kit if my car has only 2400 miles on it. i want to go from 3.55 to 4.10.

 

On some gear changes you have to but I don't know if it is needed in your case.

 

I would just get it. I took in my car last week and they told me I did not need it. It has been into the shop in and out because the gears were whining. Now they told me its the bearings on the pinion so I just ordered them and it'll be another week before my baby is ok. I'm never going back to that shop! I ordered mine from Summit Racing.
