    So I found a set of 4.56 14b gears on Ebay. Just the pinion gear and ring gear. No carrier. I emailed the seller and asked if they were "thick" gears or standard. He didn't know, so he gave the numbers stamped on the ring gear-

    2gm20026100 9 41 7 93

    Trying to figure out if these are the thick gears I can use on my 4.10 carrier?
    I would assume since there is the "gm" in the number that they are factory GM 4.56 gears and not thick.
    I know that 9 41 is pinion/ring gear tooth count= 4.56. 7 93 is July '93.
    The other #'s I have no idea.
    I'm pretty sure I answered my own question though...If I get these gears I'll need a new carrier.... /forums/images/graemlins/thinking.gif

    looks like you also have the right answer.if they were thick gears i dont think it would have the gm on it.i dont think thick gears were offered from the factory since they could build the axle with the correct parts.you could just call the dealership and ask the parts guy what that number comes up as also.
