I did 4:10s with 55000 miles and didnt use a bearing kit
Not with 4.10sYou don't have the power to top them out. Theoretically it's like 180 or 190
yes i am a DD, ithink im going to go with 4.10Get a bearing kit. The ford racing kit is 99 dollars from summit and it includes all the bearings, seals and races for your rear end. Well worth it. Every person over 50k miles or so I recommend changing the bearings and seals.
Are you a DD? I did gears on my friends car that has an 04 gt manual and it made a big diff.
hey i noticed you running a auto, do you have a shift kit of anysort?I would do 4:10s too. 4:30's you will top out at 100mph with a normal street tire and rim. Inless you run 15in rims and a tall DR's or slick all the time I wouldnt' go over 4:10s bro
