After I get my sterio and exhaust squared away I might be putting in new gears. If so which ones would be good for alot of acceleration. Ive heard that people that put 4.10 gears in their car dont drive over 150 miles. Why? Oh and stupid question time, do manuals have rear gears? Ive asked alot of people and they are just like "huh?". Help me out guys!

ok, to answer your "stupid" question, yes manuals have rear axle gears. in fact ALL cars have some type of gearing whether it be in a transfer case or rear differential. gear swaps in front wheel drive are virtually unheard of but it can be done.

i don't really understand the miles question though. do you mean they don't take long trips?? or they only get 150 miles per tank??? if it's no long trips, it's because 4.10's will give you pretty poor mileage.

Well lets start with the main point of what gears are(I'm guessing that you got a different idea from the manual question). The rear gears are in the differential (pumpkin) they set up the ration for amount of drive shaft turns per on rotation of the axel(and tires). So to make the point, yes manuals have rear gears.

As for a good ratio, I'd go with 3.73s. As the gear ration goes up it allows for a better mechanical advantage for the engine which allows the tires to get moving easier. However the increase gears means the it takes higher rpm's to reach a speed than a lower gear ration. Thus with 4.11's you may be pushing up to 4000+ rpm trying to go 70 on the freeway.

On the web site the guy said that people he knows got 4.10 gears and they love it but none of them will travel over 150 miles in one ride. I dont really know what it means tho.

My guess is thats about as far as they can go before needing gas.
Putting 4:11 gears behind a 5 speed would be pretty fun.But behind an automatic trans,well....a friend put 4:11's in his 85 firebird,(305/700r)the overdrive wouldn't hardly engage until 70mph.Or somewhere in that area.He sold those gears and bought a 3:73 and all was well.

so 3.73 would be the best for me?

Thats what I would go with.
With the 5 speed you could probably get away with the 4:11.

I would recommend 4.10's and I think the whole 150 miles thing means is that you do eat more gas, you do rev higher as for 70MPH =4,000 RPM I do think it would be that high. Take you tire height and go to the calculator on the equations page it will let you exactly know your RPM for tire size at any speed... Everyone says's 3.73, why not keep your stock gears and just add a locker if all you are jumping to is 3.73?

4.10s?????? I think thats what I will stick with. So how much would it cost to put these in? Thanks!

Gears are like 195.00 a locker or posi unit will cost ya 295.00, labor will run ya 300-400 bucks... A rear end ends up costing some coin....

Wow, 4g's at 70? Not for me...I do too much highway driving. I like 26 MPG on the highway Also, I kinda like letting the engine loaf along at 2500RPM at 75.

Has anyone gone from 3.42s to 3.73s? I see what Brian is saying about it numerically not being much difference, but is there a somewhat better launch?

Before ya assume your car will run at 4G's go to the equation calculator on the other page and punch in your tire size and really find out what your car will do at what speed and where your RPM's will be.. If your loking for a better launch and times why not just keep your 3.42 and get a locker and some lower control arms and get a nice gain in traction thus more acceleration.. Cheaper, easier to do, and less wear and tear on the car's rear... Just my humble opinion..

The 4000rpm comment was just a guess, to kinda prove the point of higher rpms, don't take it too literally. The car will run higher rpms but I'm not sure exactly how high. Sorry if I threw anyone off.

Ah, I see Pods. No biggie anyways. When I changed the rear end fluid at 75k miles the rear end was perfect...I won't bother to change the gears til the existing ones blow...too much work for too little a gain!

What do you mean by a locker?
