well i just recently bought a seperate 10 bolt with 3.23s in it and the reason i bought it was to put 3.42s or 3.73s in it and if i blow it up i have a backup just incase, my question is are 3.42s just as good as 3.73s or should I just go with the 3.73s?? and what kind of install kit should i get, do i need the ratech regular kit or the deluxe kit???

right now i have crappy 2.73s and am anxious to see the difference these bigger gears will make.

If your gonna do the swap anyway, just go with the 3.73's. As for gains, you'll prolly drop .3-.4 in the quarter and pick up 3-4 mph.

Anything is better than a 2.73, but yeah, go with the 3.73s.

3.73 is the magic # for A4 LS1's

well i will soon find out then lol, cant wait to get 3.73s in and see how she runs. and also what install kit should i get?? is the regular kit good for a gear swap and does it come with everything needed for it other than the fluids of course.

I change my 3.42 for a 3.73 but mine is M6...I don't like it!! I feel like I'm only spinning and it feels like I've lost high speed power...

I found the Ratech kit in basic and complete versions. You will want the complete kit, since it replaces the bearings as well. I found one on ebay, but I am sure our sponsors carry them too.

yeah i was thinking might aswell change everything to new to make sure it lasts for awhile and i dont have to tear into it regreting not getting the complete kit.
