    <font color=purple> Is there anywhere in the VIN # that's tells what gears I have ? Is there anywhere else I can find out ? What is the best way to figure out what they are ? I'm moving up to 35's from 33's this spring and I want to be prepared for any changes I may need.

    Its probably not the answer you want to hear, but i think you should just pull off the diff cover. Think of it as maintenance, you'll get to change the cruddy gear oil in there, clean it out some with brake clean, and find out your ratio for certain.
    Every diff I've had the cover off of had numbers stamped on the edge of the ring gear, on my 14 the numbers are 41:11. Thats ring gear teeth to pinion teeth and works out to 3.73's.

    It not a time consuming job, just one that gets overlooked often anyways. You might find a code from the glovebox but that isn't a guaratee that someone hasn't swapped in something or changed ratio's, or even glove box doors.

    Try rotating a rear tire exactly one revolution. As you do so, count the number of times the drive shaft rotates. If the drive shaft turns just over 4 revolutions, it would be a 4.11, about 3 3/4 would be a 3.73, about 3 1/2 would be 3.42, etc.

    Ok Riz... here is a pretty easy way to go... look in the glove box for a sticker that lists the code options for the truck... if there isn't one there then you'll have to crawl under the truck and get the code off the axle... should be on the pass. side circular portion of the axle. Then you can go to this page... It has all the code options for GM listed. Didn't look but probably has 3.42's if it is eighties... seventies would most likely be 3.73... also could have slug 3.08's like mine... soon to chage though!
