I’m running 35” tires with stock gears on my 1999 F150 (4x4)
Right now, the truck is slow when taking off, I want to “squish” those tires from holeshot.

I want to change gears, but really don’t know what size I need.
What do I need? 4:10? 4:56?

I also ride on highway, but I'm not interested to ride over 65-70 MPH. Just if I got some emergency.

Where can I order those gears? Is there a complete kit? (front and rear)

Thanks

 

Its been talked about a thousand times but alot of people love 4.56 with that size tire and if you want to go bigger u got the right gears. not to big of a diffrence between 3.73 and 4.10 i mean not worth the money imo
