4.10 Gear ..how much will I lose?

I maxed my car out stock(aero limited) at 150 and with 4.10's, I hit 150 with 500 rpm to go before redline. So no, they will not hurt your top speed unless your car is an extremely fast open track car.

The only draw back of the 3.90's is that they
are made of a softer metal than Ford Racing Gear's and the tend to
wear out quicker but,the best gear's for your stang are the Ford Racing
Gears because they are made of a stronger metal and don't wear out as
fast. I would get 3.73's or less if you drive on the freeway/interstate
alot or are one day going to have a power adder.3.90's or more if you
drive more on the street or are going N/A. With 4.10's fifth gear is very
useable and you can pass someone without down shifting! FRPP 4.10's
are the best in my opnion!
If motive makes a race only gear maybe but street gears are not softer. I know for a fact richmond makes race gears and those are softer. Motive gears are just as good as FRPP.
 
Yeah, they have the potential to reduce your top speed. Let's see what it will take to do it.
1st) lowered car
2nd) no speed limitor(ford ecu has it limited to 153 mph)
3rd) no police
4th) no air restrictions (when you're going that fast aerodynamics play an important role)
5th)A big set of balls

Let's see.....
1) My car has Eibach Springs
2) Superchip will fix speed limitor
3) I know all the cops 'round here
4) nose to toes - AEM cold air intake, BBK X-Pipe, Magnaflow exhaust
5) yo tengo cajones GRANDE LOL

So I should be ok, eh? LOL

Gears

Richmond or Motive gears are made of a softer metal.They also
don't fit as good as FRPP.Thus your ring and pinion will wear out
quicker.I would only buy FRPP GEARS because they are made for
FORDS in general there for they fit better and will have a longer
life.I had motive 3.90's in my old 91 LX 5.0 for 50K miles and ended
up wearing out and had a slight whine sound to them.They were
installed correctly also.So,right before I sold my 5.0 I replaced them
FRPP 4.10's and they fit great plus also the slight whine was gone.
This was my experience so,to each his own. DON'T FEAR THE GEAR!
FRPP Gears on the way! :nice:

6000 rpm in 5th gear
3.27 = 209 mph
4.10 = 167 mph

Those are completely theoretical based on rpm and gearing, and do not mean $hit because they do not factor in hp and aerodynamic drag. The car would never even be able to reach those kinds of speed with out a whole lot of power. A lot more then 99% of the cars on here have. You would really need a long stretch of highway, some huge balls, and no brains to go that fast to see a loss in top end speed. So stop worrying about it.
 
I would go with 4:10s in a second because after this thread i am convinced thats what my 95 auto needs. But im still stuck on the speedometer being WAAAY off. Plus its going to suck when im trying to re-sell the car and the potential buyer looks down and sees 89 mph when their doing 75 :D Plus i dont want to speed another $100 on the correction of the speedo after i spend a good $250+ on the gears and installation....
 
I wouldn't get 4.10's with an Auto, because if you race at the track at all then with 4.10's your 3rd gear would end at alittle over 100 and you don't want to shift into OD at the track. I think 3.73's or 3.90's would be good for an Auto.

I have a 2002 Automatic GT with the stock 3.27's and i raced my friend that has an 03 Automatic with 3.73's and even more mods and i actually started to pull on him at about 80 mph. i think his car is just a turd though! lol but i also know another guy with an 01 auto with 3.73's and did nothing so i think 4.10's are the way to go with autos.

Ok, but when your times start to suck because you have to shift into OD, I hope you have enough money to go back to a 3.90 or 3.73. I'm sure 4.10's are fun on the street, but they just aren't a good gear for 1/4 mile racing.

I have 4:10s and this might sound crazy but I wish I had bought 4:30s just for fun, I dont go past 120 anyway and staying n/a at the moment. With the 4:10s I redline in third in the 8th mile. The problem with what everyone is saying is that that only trust ford making a gear that fits perfect and you want something that fits perfect when dealing with your rear differental, thats why a bought frpp. I considered 3:90 motives but I wanted more. Also the gas dosent get hurt too bad and who cares about top end, acceleration is whats important in my opinion

Unless you are trapping at over 110-112mph you shouldn't be shifting into overdrive.
