Default 373's on highway used car?

I want to put gears in my car but am afraid the revs will be too high. It is a daiily driver and runs the highway 25mins each way to work and back. Are 373's a good choice or should I go with 355's. Anyways thanks for any help.

get 4.10's!!!!!! There is a minimunal difference in rpm's (like 200rpm) DO NOT GET THE 3.55!!!! You will not be happy with them at all. I have a auto and do a good bit of highway driveing and when I get gears (next month) I am going to get the 4.10's!!!!

You give us no information on your car, year, transmission, tire size.....

DIVER8374 is correct, with a 3650 trans it's only about a 200RPM difference between 3.73s and 4.10s

Go with the 4.10

Check out THIS LINK to see what you will tach with different gears

My car is a 2002 GT, 18 inch 1996 Cobra rims,

My gears are stock
with 4:10's what would be the RPM difference at 60mph?

thanks for the site. Revs would be over 2100PRM at 70MPH. Would this effect the life of the car if driven at that RPM everyday?

You should be just fine @ 2100RPM
Go ahead and doun shift to 4th and drive at 2100RPMs for a while to get a feel of how it will be, if you have an exhaust on your car it usually puts it into the "drone" area.....but I like that sound

Yeah, assuming your car is a manual those RPMs are about correct.

You will find a BIG difference on the highway if you go with 3.73 or 4.10 - I have the 4.10s in my car and they **** me off on the highway but I don't see that the 200 RPM difference between them and the 3.73 would be much different.

The 3.55s are a waste of time and money - you won't notice much difference between them and the stock 3.27s

You can't really win this battle. It's always going to be a compromise.

you're talking a 200rpm difference between 3.73 and 4.10. i got 3.73 and wish i got 4.10 after i got used to them.

I like the 3.73's. Better for highway driving. And I think best for an all around street car.
