rear gears

how much of a noticeable difference will i recieve from putting 3.73 gears in? also how much would my gas mileage go down? I have the same questions for the 4.10 gears. my car is a 96 3.8, auto , thanks in advance

The main difference will be in the RPMs, I also heard that gas mileage isnt that big difference too. 4.10 gears arent also really recommended if you do alot of highway driving.

do you know what gears you have now....i think there 2.73 and if so yes you will see a big difference....i went from 2.73's to 3.42's and i felt a good difference and my gas milage got better.....it all depends on what you drive more...city or highway...i do about both equal so for somereason i get better gas milage with my 3.42's. and since you have an auto probably wouldnt go with the 4.11's

i went with 3.73 didn't notice and gas milage difference but the thing takes off like a bat out of hell compared to when i had the one spinner going

He has an RS so it's either 3.23 or 3.42, can't remember which, but he has LSD

yeah i was thinking it was the 3.42 but i could be wrong, i spend about equal time in the city and highway

3.73's wont be TOO much of a difference, 4.10s are always nice but you'llbe a few hundred RPM more on the highway and your gas milage may go down a tad, but a lot of people notice better citymilage with 4.10s

i would go with 3.73 if you are spending equal time on the highway as the cities... 4.10 is a little deep for an automatic in my opinion...

why's it better on a manual?

for example, the 5 speed v6's have a worse O/D ear than the autos (.72:1 to .70:1 or soemthing liek that) but some people still say "oh max 3.73 for auto... 4.10 for manual..."

well generally it is correct, i didnt' know v6's top gear on there auto was more shallow than top gear on the manuals... most of the time its the other way and 4.10's are usually too deep for an auto, because they're top gear is generally deeper than manuals...

just because it doesn't apply for v6's doesn't mean that it is usually a good rule of thumb

you're all just too pussy for em :evillol: but I cant talk till I get em... which wont be for a while due to $$...

i just wouldn't want to top out at like 90mph... no matter how fast i get there i like having a high top end...

keeps you from getting more tickets :shrug: lol

lol i think you meant to use this one :dunno:

screw tickets i have 7 tickets and 2 wrecks, and still drive the same way haha

haha I have... 3... no 5... no 6 tickets (2 got thrown out, 2 got reduced, 1 was 0 points tintd windows ticket) and about... 3-4 verbal warnings (speeding, loud exhaust/slight speeding, loud exhaust/no front plate) and one accident... I drive a little more carefully now...

and and the one ticket from my accident that was also reduced

Whats the highest you can go on a 4.11? If its 90 MPH, screw that!

when i had the 305tbi with a 700r4, when i switched from 2.73 rear gear to 3.42 i topped out at 90mph... idk how quick you'll top out with 4.10's, but i know way too early

it depends on how much HP you have a lot... right now with 3.42s when we turned my car we guestimated it wouldnt top out till liek 140ish


And on 4th gens it's 4.10s... whats with everyone and 4.11s geez lol

no actually i ran out of gear at 90... my earlier engine got me up to 140 with 2.73's so there wasn't any horsepower problems

I'm talkign about my car

when i had the 305tbi with a 700r4, when i switched from 2.73 rear gear to 3.42 i topped out at 90mph... idk how quick you'll top out with 4.10's, but i know way too early
thats wierd because i have the same set up with 3.42 gears and i can go over my 115 marker on my speedo....

lol of course it goes that high... have you had you're speedo corrected yet? my speedo would read 120... but in reality i was goin 90

ya....ive got my speedo fixed...

ummm i dont feel like starting a new thread cause its about the same thing but what web stie sells cheap rear end gears? should i put some 3.23(is that one of the sizes they come in) gears in my 88 2.8 just to get it a little faster and maybe people will be like hmmm car is fast enough for my son......and buy it. also how hard is it to actually swap out the gear? like minutes?

not minutes more like hours expecially if its your first time...and summit is always pretty cheap...get the gears and the install kit and youll be set...Id go with 3.42's or 3.73's

im thionking 3.42, think 3.73 would be a little over kill
