i have a 98 ta A4 that is a weekend street warrior and have decided to go with 373 gears. What my question is is there a brand that is better/ stronger(yes i want your opinion) also i have looked on websites and seen 373 gears for 7.5" and 8.5" 10 bolts what does this mean? so what ones would i need?

If your riding on the stock 10 bolt, you want the 7.5" option.
Richmond and motive are both good brands. People will have their own opinion on which is better.

ok thank you also what all is needed for the kit to install the gears

You should spend the extra bucks and send the ring and pinion out to get them Cryogenic treated. This process will strengthen the metal and the gears will last longer.

is that a joke or for real? The only time i hear about cryogenics is in movies how would that help by freezing them?
if i buy gears will all parts be included to put them in or will i have to buy other parts?

Depends on where you get the gears from whether they come with everything. You will need shims, a new crush sleeve, possibly bearings if they are worn, gaskets - rear end and pinion if you can't reuse the old ones, and gear fluid. If you've never done them before I highly suggest either taking it to someone to do or have an experienced friend help you out. I had a friend show me how and I can swap out a set in about 2 hrs by myself taking it slow (drinking I mean). As for better gears - it's really a toss up - I have Richmond 4.10s in mine and I like them but they do make a bit of noise - whine. I've heard that Richmonds tend to do that. Your call really.It's not how fast you can go. It's how fast you can get there.

Dude, not be-n a smart ass but if you don't have much knoledge of gear & rearend sizes
you would be better off letting a good shop do the install @ they will have all the correct parts needed!!........Again not trying to be a smart ass, just trying to save you a little frustration & money (cheaper to pay somone to do it rite one time)

i dont know much about the rears if i did take it to a shop to get it done which i will i wonder how many hours they could charge me to do the job?

It is best to get the gears from the shop installing them, if the set YOU purchased does not pan out (i.e. howling, excessive noise), it is on you, if you purchase the gears from THEM, then it is the shops problem to find the set that is cut exactly correct.
