The stock gears should be 2.79's but some special ones came with lower but you most likely have the 2.79's

You can figure it out three different ways

1) Axle code on the drivers door tag (assuming they were not swapped out after)
M=2.73
Z=3.08
E=3.27
K=3.55
W=3.73

2) Lift the rear off the ground, spin the tire exactly one time around and count how many times the drive shaft goes around.

3) Guess
