will like it said, what do they do

LilRoush

It's like the gearing on the back of your bike. When you go to a smaller gear on the rear wheel, you don't have to turn your peddles as fast to move the rear tire as much.
The same idea translated to your car. .... but the number is a representation of the rear axle's gear as a raito (3.27:1).Going from yourstock 3.27 gear to a 3.73 or 4.10 gear will turn over the rear wheels a lot quicker when you accelerate.

increasing you acceleration?

LilRoush

Yeah, the place you'll notice the improvement is when you hit the gas pedal.

Not to High jack your thread but I have an entire your 3.73 gear set/ package whatever you want to call it ( everything you need for the install) for sale. The T-loc, 3.73 gears, The motive bearing kit and if you have a 94-98 mustang I have the Speedo correction gear. Again sorry Im not tryin to highjack your thread or anything but I just bought all this stuff thinking I was going to put them in but something else has come my way and I am going in that direction PM me for more details

the mustang im hoping to get is going to bea 2000, or 2001. (First car after i get a job) So how much would all this stuff required to do the 3.73 gears cost to do? How hard is it to put in? (i will have some people who know more about cars then i do help me)

Well all the stuff you need will be about 550-600 dollars plus the install which is anywhere from 200-400 I believe make sure you shop around. You usually want a shop that you trust to do the work for you, but if your friends are pretty good with cars and know what they are doing i dont see why they wouldnt be able to do it
