So whats your opinion on these, will they be good for highway driving, does tires spin alot more, how close is 1st to 2nd, I notice you where chirping the in 3 gear, I like that.

 

Bill i couldn't help but laugh at the shaky cam Looks like he was definitly enjoying it though

Now you got me wanting to make a video like that..... the car will go all the way to 4th before the tires ever have a hope of hooking up

 

Well, since mine isn't a daily, I can't really say how they'll be commuting long distances. From what I've read here, mileage suffers by 2 mpg and highway rpm's go up by 300.

How close is 1st to 2nd? Closer than when the 3.55's were in. At full throttle, re-watch the vid.

And yes, I grabbed a chirp going into 3rd... never done that before.



Oh, we both had a blast!

 

For those who have concerns about installing 4.10 gears. I think it was tom281 who said it best. DON'T FEAR THE GEAR!!!
With a final drive ratio of 4.10 multiplied by the 3650's final O.D. ratio of .67 you end up with a 2.78 final drive ratio in O.D.
Many would consider this an ideal ratio for high speed crusing. Even a pushrod motor would have no problems crusing it high speeds with a final drive like this. So for those of you who are sitting on the fence about 4.10s just do it! The huge performance increase is well worth the marginal loss in highway fuel economy.
Also keep in mind these are not big motors, they need some gear to really work well.

 

I think you pretty much just pushed me off the fence. Ive been contemplating 4.10's now off and on for about 6 months now, now I think im just gonna bite the bullet and get them.

 

Me too.

 

Me three. What's the benefit of the diff cover besides it's great look?

 

I'm getting my 4.10's installed this Thursday!!

 

Do the 4.10s..... get off the fence, and get them installed.

 

The additional thickness of the FRPP girdle adds strength to the differential housing.

Also, there are 2 special load bolts (on the girdle) that support the main caps, which are under stress during launching and acceleration.

 

You guys are killing me, I went from being content for the time being to ready to rob a bank to finance all the mods I have on my list!

 

Bill,
thanks for the info. I'll add it to my list of gotta haves.....

 

Way to go Bill - at least you didn't put up a poll I told you the 4.10's would be worth every cent

 

Ahhhh - the Professore......

 

Hey are these guys responsible for those TV Dinners?

Just kidding! Looks great a real clean install. Bill what made you pick a 4:10 set up? Just curious in case I do mine. Did you refer to any kind of RPM guide by Ford Racing based of your 5 speed trans? Most of us want better ET's in the 0 - 80 range I imagine. It's not like were going out the the salt flats for max MPH (maybe yes? matbe no?).

What is your thought on a Aluminum or carbon fiber drive shaft? It this you your future?

You did!

The 4.10's have been on the back burner for quite some time. Finally scrounged up enough cash to get um' done! No regrets.



Bill, I wanted some big 'bang for under the $1k buck', Since I already have the CAI/Tune combo, gears is second on the list. It's common knowlege in the Forums that running 4.10's will add around 300 rpm's on the highway and will lose around 2 mpg. To me, this was more than an acceptable trade off. To some, 3.73's may be a better option, but it's just too close to the 3.55's I had.

0-80+ is where the 4.10's shine through!

On the 1-piece driveshafts, I considered them at one time. But, I'm seeing comments about them that don't quite give me that 'warm & fuzzy'. Maybe once I start reading above 95% sucess stories, I may once again consider them. But, it sounds like the manufacturers of these 1-piece D/S's haven't ironed out all the issues.

 

Haha I like your kids peace sign in the beggining.

 

Made another video yesterday with my son. Nothing special, just screwing around. I'll think of any excuse and reason to take the Mustang out for a spin!
