Question Rear Differential

I'm thinking about putting 4.10 gears into my mach 1. Its a stick with 27k miles. Its also my daily driver. I do not street race but I do plan on taking it to my local drag strip. its a 1/8 mile. If I do get the gears should I change out my Rear Differential? If the answer is yes, I would like to know if i should stick to all Ford Racing parts like the 4.10 kits off of this site: brothersperformance.com. or would it be best to just buy the parts and not the other stuff???

Re: Rear Differential

4.10 gears are not enough for the 1/8th mile. Step up to some 4.30s.
