Somewhere between 2.73 and 5.13 I would say. You can also tell by looking at the tag on the diff cover. Or my favorite method of sticking your head under the tire and count how many times the tire spins per driveshaft revolution while your buddy does a burnout on your face.

Edit: and for the love of god dont forget the bleach

you joind in 2005 and still dont know how to tell what gear ratio you have or how to search the internet? hang on ill let my girlfriend tell you how to get the ratio....

Ok, you have 3 choices..

1. Read the ID tag on the Diff. cover.
2. Spin a tire and count the rotations of the driveshaft.
3. Pull the Diff. cover off and count the teeth on the ring gear and pinion then divide them.
