No some come with 2.73. Check the codes on your glovebox for your gear ratio.

GU3 is 273, GU5 is 3.23 and GU6 is 3.42 and all will be on your RPO sheet inside your glove box (for 93s).

And if you come across an S10 with GW8/GT5 (not sure which RPO is for S-Series) that's 4.10s and GT4 is 3.73s. Older ones (mid 80s) with H04 have 4.11s. If you feel REALLY crazy, 4.56s are HC4
