To find the gear ratio of a *specific* 1995 Chevy 4x4 Z71, you'll need to:
* Check the vehicle's specifications: Look for a sticker, usually located in the glove compartment or on the driver's side doorjamb, that lists the vehicle's options and specifications. This *might* include the axle ratio.
* Check the owner's manual: If you have the original owner's manual, it may specify the gear ratio.
* Look at the differential tag: The differential itself (located in the rear axle) will usually have a tag or sticker that states the gear ratio. You'll need to jack up the truck and possibly remove the differential cover to see it.
* Measure the driveshaft and tire rotations: This is a more involved method requiring specific measurements and calculations.
Without the VIN or other identifying information for a specific truck, it's impossible to give you the exact gear ratio.
