i went w. 3.73s a month or so ago, and now am putting in 4.10s... so that ought to tell ya something... and its still my DD

 

I went with Richmond Gears, as you can see, so I if do decide to to go with a bigger gear who would you guys reccommend?

 

i went from 3.73s to 4.30s and i wont look back, i drive mine all the time almost everyday, around town milage is about the same, you use a little more on the highway but its not as bad as most people make it out to be, just go a little slower haha. ford racing has a good product at a good price, thats what i went with

 

yelw02gt I wanted to drive the car home in about a month. It's going to be a 1300 mile round trip. Like I said earlier it's not a daily driver but the question that I have will it hurt the engine to go that far using 4:30's?

 

its not going to "hurt" then engine persay, but if your used to going 70 mph at 2000 rpm with 3.73s, your gonna be over 2500 rpm at 70-75 mph so you can say its more engine ware...just go a little slower is all

 

Yeah I was thinking 70 no more than 75. This will be the one and only high mileage drive. Can you tell me everything I will need to do a successful upgrade? Maybe even part numbers!!!

 

you need your ring and pinion obviously, you need a master instal/rebuild kit which you can order online or at like advance auto or napa or whatever and gear lube, the instal kit should* have everything you need for the instal
