    I'm lookin on ebay at 3.73 gears for my car and I found a guy that is selling his that have 55k on them already. They look like they r in good condition (no ackward wearing) but i'm not sure how long gears are "suppose" to last. Is the $60 bucks i'm gonna bid on them worth it or not?

    I have 4.10 in my 00 GT and at 80 MPH I'm right at 3K rpm. Not too bad IMO. On another note, I for one sure as hell wouldn't buy used gears. Yeah they might hold up but the chances of you getting those and having someone install them and getting them right on the money is almost impossible. More than likely they will work, but it won't be the right pattern and either whine like a MOFO or wear out in no time flat. I bought my gears and install kit(which if you wanted to shave money you could go without an install kit) from Drivetraindirect.com. They have pretty good prices. Go with either Richmond or Ford Racing. These are all my own opinions. I've put my gears through living hell and back and they are still fine. Trick is to get them set up right. If they're set up right you're golden. Don't fear the gear!!!!!!

    Edit: the difference between cruising RPM's of 3.73 and 4.10 is around 200-300 rpm. Not enough to even question 4.10's. But then again that's me. I'm 22 single and like my shit loud, quick, torquey and don't give a fuck about gas mileage.

    People say that there isn't a big difference from stock gears to 3.73. I'd get 4.10's

    if your not gonna be doin much highway use then 4.10 even though i wouldnt agree

    personally id stay at 3.73.. if 3.73 are just not quite high enough go with a 3.90

    4.10 is just like a straight strip gear

    4.10 is not a strip gear only. I run it everyday. I get on the highway to get to work everyday. I'm telling you there is not much of a difference in cruising rpm in OD. Not enough to worry about it or loose any more gas mileage.

    4.10's manual or auto here. I orginally came from a set of 3.73's.

    4.10's are much better for the little peanut motors. =)
     
  9. you didn't say weither you have a stick or auto.. for auto most guys go 4.10s and for stick most guys go 3.73.. as for the used gears.. go for it 60 bucks aight $hI^

    i would go with 3.73. a friend of mine has a 87 gt and i pt 4.10 in it. he takes way too long to shift and that slows him down a lot. 3.73 will make the gears at far as redlinin the motor last longer. just my .02

    Gears are something that should be bought new.

    I have been running 4.30's in mine for over a year now. 2500 rpms @ 70mph with 27.5" tall rear tires. If you're gonna run a power adder(n2o, blower) then 3.73's are a decent gear. If you're gonna stay N/A then I would go bigger. I started with 3.73's then bought 4.10's then bought 4.30's.

    I was thinking of going to 4.56's but some made me an offer on my engine so it's gone. And now I'm building a 427 stroker that should put me into the low 10's high 9's N/A:coold:

    Shit those are tall tires. What would the RPMs be at on a stock drive train (T5) with 3.73s? 16" ponies with 50 series tires. Rough guess. I was lookin at 3.55s, cause I do a lot of highway miles, but if its not a huge difference in economy I'd go with 3.73s. I need some more boot down low. Just gotta finish off my exhuast sometime this week.

    I went with 3.73s and was quite pleased with them. I'm glad that I didn't go with the 4.10's for gas miledge reasons.

    Then again, my stock gears were 2.73s so it was a big jump :bigthumb:

    a 4.6 would be better off with 4.10s than 3.73s, imo.

    Get them new, btw. Ford Racing or Richmond make great rear end gears.

    Of course, you can't go wrong with the all-might 3.55s.
