There's a sticker on the diff cover that tells you. If you don't feel like looking at that, generally speaking, performance pack cars get the 3.73 gears, regular cars get 3.55. Unless you have an automatic, in which case performance pack gets the 3.55 and regular cars are 3.15.

Your door jamb sticker has the axle code on it to look it up.

BB. 3.73
DD. 3.55
GG. 3.31
YY. 3.15
