what is the gear ratio

you will have the same ratio front and rear, there is a axle code on the rear axle, the code should be right by the diff, cover. Take this code and call a dealer and they will let you know what the axle ratio is. hope this helps, best of luck.

Somewhere on the driver's door or body area of your vehicle you will find a sticker that has the VIN across the top, GVR, tire size, and other information on it. At the bottom of that sticker it will show an "axle code". Take that information with the VIN number to any dealership and they can get the gear ratio and tell you what type of rear axle is in the vehicle. SOMETIMES, if you crawl underneath the truck, there will be a tag on the rear axle cover (held on by a bolt) and the gear ratio will be stamped into the metal tag.
