Whats the difference between like 3.73 or a 4.10 can anyone help me? I want the best gears

 

I went with 4.10s and have never looked back. My car is running about 2200 rpm at 70 and 2400 or so at 80. I'm getting about 21 mpg average. I have TONS of low end power, and the car will still go way faster than I want to drive it.

 

like what do the numbers mean?

 

Found this for you -
The term gear ratio simply means the ratio of # of teeth between two meshing gears. In a system where two gears mesh together, one of the gears will have power applied to it (the drive gear) and the other gear (the driven gear) will be turned by the drive gear.

The ratio is simply the number of teeth on the driven gear divided by the number of teeth on the drive gear. In the case of rear axles, the pinion gear (the drive gear) has X number of teeth and the ring gear (the driven gear) has Y number of teeth. If we divide Y by X (Y/X) then we get the gear ratio.

For example, a ring gear that had 43 teeth and a pinion that had 11 teeth would be a gear ratio of 3.916 (~3.92). A ring gear that has 39 teeth and a pinion that has 11 teeth would have a gear ratio of 3.545 (~3.55).

 

Well so what would be the best one I'm thinking about going with 3.73 gears

 

What do you have now?

 

Stock v6 auto has 3.27s. Get the 4.10s. Actually scrap getting gears and get a used 8.8 Axle with 4.10s already in it, then you'll have an LSD instead of a one wheeled wonder.

Buy this, bolts right in and cost the same as a gear swap anyway.

they don't have it for the 03 V6 :/

 

It should fit. But you've come to the right place, Alan and Clint will help you get the right setup.

 

I'm just gonna go with 4.10s
