anyways here is the deal. a friend of mine had a brand new set of motive gears from his TA that he never used. although the gears are brand new and he says they are 4:11's is there ne way i can tell they are what he says they are?

I am not sure if you are asking how to check the ratio but if you are.... just count the ring gear teeth and divide by the pinion teeth. I think it will be 41 and 10 teeth. My 3.73:1 gear is 41/11 teeth.

This is correct! That is the easiest way to be sure if the gears are what he says they are! Same thing i did just to be sure i did get the correct gears!

One time the dealer tried to void my warranty by accusing me of swapping my gears when they worked on the rear end a few years ago. The mechanic and his supervisor just read off some numbers stamped on the ring gear, which did not indicate any gear ratio in any way. Finally someone knew what he was doing and shut his supervisor up by counting the gear teeth. I never forget how to find out a gear ratio since then.

Oddly enough, my stock pinion had 12:41 stamped right on it. It was visible once the cover was off.

From my expirence most gears sets have some sort of a stamp on the ring gear that says the ratio. If they don't count the ring gear teeth and divide by the pinion teeth; that will give you the ratio.
