Aren't gears only worth .20 in the 1/4? The driveshaft is also worth .20.

ok sounds like theres too many drawbacks if I'm gonna keep the car forever.....

so how does the aluminum driveshaft help? less weight?

I have 4:10's and love them. Rpms are only 2800 at 80 mph. Someone explain to me how you lose hp and torque with them? It just changes the curve.

Less weight, but better yet, less rolational weight which is a parasite for power.

First of all, there is no such thing as a stupid question, but there are a lot of inquisitive idiots. Just kidding. I couldn't help that.

With gears you will lose some highway MPG, and HP to the wheels. You will gain torque to the wheels and have quicker acceleration. If you do a lot of city driving, it will enable you to get to higher gears quicker and slightly increase your MPG. On the highway you will be doing higher RPM for the same speed. If you're doing burnouts now, it will make it easier to spin the tires. You probably have a 3.31 or 3.55 rear. If it's a 3.55, you won't notice much out of 3.73. That being the case, you also won't notice much MPG difference by going to 4.10 from 3.55.

Personally, I still can't decide between 3.73 and 4.10 as I do mostly highway driving of 500 miles one way every 2 weeks.

I'm not following this at all.... how do gears effect horsepower??? Someone please explain... I think its nonsense. but what do i know?

then dont let them touch the rear end, period, no helical cut gears will whine if properly installed

with 4.10s you will loose 2 mpg at 75ish mph on long trips gears just multiply the torque to get u in the power band faster, like the old 10 speed bikes, 5th gear can be like 4.10s, 10th can be 3.31s

they affect Rear Wheel horse power only not at the crank....

I cant expalain why.. its a physics thing... someone more knowlegable than I could chime in...
