depends on the year and drive ratio. the 98-03 z71 silverados had 285 h.p. stock. that was a vortec intake 4L60E trans. and 3.73:1 gear ratio in the differential.
If you call a GM dealer and give them the VIN# they can tell you what gear ratio you have.
All you need to do is write the VIN# down and call a GM dealer and ask for parts. Tell them you would like to know the gear ratio in you truck, and that you have the VIN# Thay will tell you what it is.
