I am dropping off my truck today to have the 3.55 gears swapped out to 4.10s, I've been saving up for a while. Using Ford racing gears and its gonna cost about $1500 installed for both front and rear, I guess this is a pretty fair price.

My tires are 33" so I am hoping to get my rpms back into a power range, especially on the interstate (I only turn 1700 rpm at 70mph, no torque). Anyways, do you think it's going to make a good difference, is it money well spent? I still think a supercharger will be my next investment, but that's a year away or so, you know $$$

 

I would have gone steeper on the gears but if you truly are getting a s/c you made the right choice.

 

That's odd, my truck came with factory 20's and a 32.1 tall tire stock. I went to 33's with my 3:55LSD and at 70 I am right around 1840rpms and have plenty of power. I am actually hitting the rollers next tuesday to see what she lays down. I am told it's a factory freak truck because I can also turn the 33's for about 35' or so before she shifts into second and boggs down. As for power, I felt little to no difference with the tire size.

 

You'll love the change

 

i cant decide if i am going to get 4.10's when i get my s/c. i do alot of highway driving and i think it would be really annoying especially with my exhaust setup to run at close to 3k rpms for 5+ hours

 

How are you liking those cooper tires?? thinking that might be my next set??

thanks

$1500 seems a lot to me for gears and labors unless your add locker or limit slip diff....I was qoute 4.56s for my truck $975 thats only for gears and labors.

YOMAN!

 

is that a 4x4 or 4x2? are you getting both done? $1500 is a fair price ive been quoted $1800 for front and rear

 

Yes, that's for front and rear. The cost of the gears and the install kits is $800, just for the parts.

This is a tough job, not one for a novice, and this guy does a lot of them, only bad thing is he's a big GM guy, does a lot of speed work on GTOs and Camaros. But I trust his work.

I guess my only concern is ending up at an RPM during insterstate where my exhaust drones a little. Its a Magnaflow catback and not real loud, but I know sometimes it resonates a little. I am looking forward to the difference in seat of pants feel.

 

hey pimp how you like them tires? hows the treadware with everyday driving?
i have to get a new set soon and i like the way those look, and they are a good price too.

 

LOL.. Thats probably for one because that barely covers the cost of the parts and no labors.

 

Excellent. Like them just as well as the TOYO's M/T I had prior on my last truck.

 

Im also doing the 3:55 swap into either 4:10's or 4:30's. Does anyone know what would be better. Im going to be running 33"x12.5"x20 ToyoMT's. I want my truck to be a little quicker with my new wheel and tire setup, but I dont want the gas mileage to kill my wallet. Also I figure the 4:10's come on the Super Duty's so I'm sure they would be good on my 4.6 F150. Any suggestions?

 

I have seen lower price gear $171 per axle and $65 install kit. then i know someone works at shop gave me an awesome price on labors ( he cut half price for me )

YOMAN!
