3:73 or 4:10's on 2011 5.0

Hello everyone just got my new 5.0 and it's everything that everyone said it is? However I would like a little more jump. I currently have the stock gear 3:27 or whatever it is. I should have got the 3:73 option. As of right now I think the only mods I am going to do ( at least start with ) is a gear and exhaust ... I know lots of people say the 3:73 is great for the supercharger but since at this time I don't have any plans for that I figure a 4:10 gear would give me that seat of the pants difference... Any help would be great!!!! Thanks....

For as much as a gear change is gonna cost you I would go with a CAI and tuner.Ive had 4.10s in my cobra and they 07 and loved them.Going from that to 3.73s in the 5.0 is a big difference and I would love to do them again but just haven't made my mind up about staying NA.On these new 5.0 you can basically have a FI car or NA car at 500whp for pretty much the same price.

for a daily driver 3.73 would work best. Its not a huge jump but it is a nice gain. Remember it will require a retune to set the speedo right and unless ford will do it... it will void the warranty.

Thanks guys for the info I guess it's gonna be a last minute decision.... But as of right now I'm leaning more towards the 4:10.....

I have a 2010 mustang gt with saleen supercharger and I will be upgrading my 3.31 to 3.73 very soon and if you don't plan to supercharge it then 4.10's would be best but if there is a chance you might supercharge then i would go with the 3.73's for now and just wait it out and if you have a sct x3 you can change your gears out so you dont need to re tune your car, just a word of advice?

Can anyone advise a ball-park figure for labor to do this? I have checked some sources and I can buy the gears/install kit for anywhere from $150 to $220 bucks. What is involved for the labor cost? Thanks!

Ok I bought my gears from brenspeed.com and I got the 3.73 gears with master install kit for $235 and it was everything you need to do the job and if you plan on having someone install it, my shop is charging me about $300 for labor and that is just my shop I trust and go with the actual Ford racing gears and not the motive gears, just heard they make alot of noise no matter what you do, so spend the extra 20 dollars and get the Ford racing gears, just some advice my shop told me?

I would say 3.73s unless you're throwing on a s/c in the near future. good luck!

Oohh I think 4.10 would be way too steep... Here's the deal, the tranny in the manual is already pretty steep, with 3.73s you barely make it to 60 in 2nd and you actually exit the 1/4 mile in 5th... The HP curve is broad enough that the 3.73s actually keep you in it, any steeper and I think you're just wasting power

Not to mention the low mid range torque increase from just a tuner/cai is like 60 at the wheels, you'd never even use that with 4.10s

This is for the manual though, typically with the auto you would do 4.10

Very true but if you are not gonna use it for a track car then thats no big deal.As for high RPMs on the highway.......thats what 6th gear is for.

My Camaro SS L99 has 3.27 gears, Ford would be 3.55, 3.73, 4.10.

Yeah you have a different tranny though, you have to have 3.31 or taller to come out in 4th in a 2011 manual... Or a really high rev limit at about 7800

there is such a thing as to much, you can have to much HP, you can have to much gear. I think for a daily driver 3.73 is a great choice, 4.10 while not that much worse is getting to high with the final drive of the 6 speed still not great.

I agree! And like I said if you plan to supercharge it later that's just more money later because you won't utilize your supercharger if you shift all the time?

Ya...a t45. 7800 rpm is dreamland for me. Unless I go with a 4v head.

Lord its a six speed, definitely 3.73. I have a 3.73 gear and the first three shift go by pretty damn quick.....it would almost be more work then worth it to go 4.10, I really don't think you would see a huge gain....but thats just my 2 cents.
