what exactly with I gain for putting in new differential gears?

I know I wont be able to do it myself so how much will it cost to install the pinion andring gears?

 

Taller gears will get you off the line faster and make you lose on the top end. What do you drive Bob?

 

98gt stock

 

OK, I'm going to move this to the 4.6 section for you. [sm=smiley20.gif]

 

thanks

 

They say up to .2 or a second off your 1/4 mile.

You have a 98 gt, so its probably going to cost around 300 just to install the gears. But you probably need your bearings changed and thats another 200.

Im getting gears soon and thats what a few places near me told me for prices.

 

ok thanks that good to know that theres an extra 200 probably
