4.10 gears worth it?

I have a 2007 shelby GT and was considering putting 4.10 gears in it. It already has 3.55 gears in it so i was wondering if its worth the swap? If so, would any other parts have to be replaced as well?

If you are wanting a strong launch then yes, and if you don't care about top end being sacrificed... And you do not need any other parts when adding gears

Re: 4.10 gears worth it?

Awesome, thank you. I was also considering swapping out the stock cams for some new ones. what are the benefits of new cams and what ones would you recommend?

Its good to get a rebuild kit, and you also need friction modifier and a set of extra tires would be nice

Re: 4.10 gears worth it?

One other question. are long tube headers worth the price. is it worth me buying a set of long tube headers or are the gains not worth the price?

I have no idea what a rebuild kit is... Nor a friction modifier... On all my other stangs I put 4:10s in I did not do that... Did I do something wrong??

MAC LTs are cheap and i would expect a decent gain

So yes and no, Yes you messed up not using friction modifier unless you didnt have a tru trak and No guess you dont need to change all the bearings if its low mileage car but its a very good idea

"In your Mustang, a friction modifier additive is necessary to reduce chatter. Ford Racing friction modifier is designed to eliminate gear-housing chatter in your Mustang." thats from FORD

Re: 4.10 gears worth it?

i would not put 4.10's in that car
with the torque that thing has you do not need them
and long tubes make BIG power on blower cars so I'd go for it !!!

Re: 4.10 gears worth it?

I have 410s on my stang, and I did not need any of that stuff listed, mine runs fine, takes off like a Beast, but it does lower my mpg's a little, especially on HWY. LT (Long Tube) Headers, do give you a little extra HP, but it only does in higher RPM's, If your pushing something SC, Turbo's NITrous, then you may get to feel it, if not, then you won't notice. Shorties you won't feel anything, regardless of what you have. I was going to get LT's but was warned by two Performance shops, that it was not worth the money spent, and I would get better by just adding a SC. So I took them off the list.

You need Friction modifier don't be a cheap a$$ and try to save 7.99 says in the owners manual you need it , and as far as the bearing kit goes, every good shop will tell you need the install kit, even if your bringing your own parts, its already completely apart, takes 10 extra mins to throw the bearings on, be careful of who you take advice from most mustang guys are penny pinchers, do it right and do it once

Re: 4.10 gears worth it?

I had 4.10's in an 05 GT and really didn't like them. Sure it was quicker in the quarter and launched harder but it hurt the mileage and it made first so low, I ended up starting in second half the time and the gears were noisy, they were not Ford. When the opportunity arose, I changed back to the 3.55s.... I would suggest 3.73s...

And I don't know why people say it hurts your top end. At 145 mph you turn about 4,950rpm with 4.10 gears. How fast do you want to go? With an overdrive transmission, 4.10 gears will not hurt your top end.

I think the top end they are talking about is the overall top speed!..

Does this car see the track alot? Or is it more of a dd? If dd id go 373 gears if primarlly a track car id go 410 as for l/t headers they will improve ur launch because the produce more low end torque and high end hp (old saying from shelby him self "hp sells cars, torque wins races) cermac coated MAC headers are totally worth it for sound, torque and flow! Any shop that said other wise does not know what there talking about.

Cams r always nice for sound and depending on what cams u want they deliver power and torque diffrently threw out ur rpm range but ull prolly want to do ur heads and put some beehive springs or twin race springs in then (cams on ur yr mustang i dont really know much about but the old push rod cars like mine... All i can say f-303 i love u)

A professional Mustang Speed shop did my stuff, I was not a Cheap @$$, I paid a nice piece of change to get it done, and no I do not know all the little ends and outs of what they did, used or added to get the job done. But my cars runs excellant, and I trust them 100%. My gears runs like "Champs", they do not make noises, they are fine. But yes I do notice the change in Gas miledge. Prices you pay for stuff.

All I can recommend is do your research. I have the FRPP hot rod cams and love them. My over all goal is to go twin screw later so I wanted cams that were good N/A and F/I. The thumper cams sound super mean but aren't real good for F/I applications. To answer your power question.... I did FRPP 3v intake, cams, LT's with catted x, TB, and JLT CAI and picked up just over 60hp at the wheels. With certain cams that are labeled NSR( no springs required) you don't need to replace your valve springs.... For cams with larger lift it's always a good idea to go with heavier springs and you may also need phaser limiters or lock outs to prevent piston to valve clearance issues. Just make sure you check the manufacturers recommendations or a well known mustang shop or builder for advice.

Re: 4.10 gears worth it?

3.55 vs 4.10 is about a 15% increase in rpm or so if I did my math right~ so its a good boost overall, I went from 3.27 to 3.73 and it was a meh change (about 2.5 tenths faster) so you are looking at about the same rate~ overall not bad but if the gear swap turns into a hassle (gears whine have issues) its not worth it lol

Well if it was a respectable speed shop then I assume they installed new bearings, sorry if I'm making a big deal about this but I want people to get the right info, and I've heard some people don't get chatter when they use just royal purple or Mobil 1 with out the friction modifier but I've heard some cases where it has, I have installed my own gears before and and this time around I can't do to time restraints but all shops I called told me to get the install kit and the other half said stay away from motive gears, which idk why I thought motive was good

I know that ford racing is not offer these... Try to find a set of 3.90s. It split the difference between 373 and 410.

Lol... Its pretty simple to figure out. If ur a real aggressive driver and like higher rpms and doing super fast burnouts and dont mind doing other stuff like adding a trans cooler or getting a racing drive shaft etc... Go 410. If ur looking for all that other good stuff but not quit as mod hard core and u dont mind just cruzing but still want plenty of gideup go 373. Dont waste ur time trying to find something not readally available unless theres some sort of "unique" reason to y ur doing it. It makes the job take to long and i for one am more about driving my ride then working on it. How bout you?

6,500rpm, 5th gear, 4.10 gears, your top speed would be 187.34627997540479606476737036278mph.

This 410 vs 373 battle has raged on to long, for years. Want to have the very best street light to street light and the best 60 foot 410s hell why not 4.56s however you want something that's not that noticeable and feels stock get 373s nuff said, you have a supercharger ask your tuner but it's what you want

I think another question would be that if you had an older s197 with 3.55s do you really wanna take it to a shop and spend 500-700ish bucks to move up one gear to a 3.73? Not putting down a 3.73 gear by no means, It's just not enough gain IMO

Doesn't this kinda go against what you said before, about the whole debate on 3.73 vs 4.10?...

That doesn't contradict anything I said, you are going to want them to maintain drive ability in low speeds, maybe 373s will work to who knows, I'm just saying man everybody always ask 373vs410s, how about this brenspeed tune vs bama, Mobil 1 vs royal purple, there's never going to be a right answer
