410s it is.

 

my truck has 3.55's so if i went to 4.10's basically what am i gaining a quicker jump off the line and what else quicker pickup? after reading this im interested in the swap any help would be great

 

I am also very interested in fact when I get back from Afghanistan this time
I was going to go with 4.10 but heard they make a 4.30 for 2wd I have a 2007 Ford FX2 and was wondering if I heard wrong on this can anybody let me know

 

i had recently installed 4:56's in my 06 4x4 screw which had 3:55's i now run 37'' tires and have not seen any decrease in my mpgs on the hwy i see about 15-16mpg and about 14-15mpg city. like everyone has said on here its all in how you drive!!! also i leave my edge on stage 2 (stock tune) all time if this helps, dont forget to reprogram you gear and tire ratio. hope this helps

 

I believe 4.30's are only available for 8.8" rear axles.

 

So where is the best place to get a set and what all is needed do I need the bearing kit that they offer or just the new seal and gasket kit?

Found a set of 4.30's for 9.75's.

Ford Racing makes a set of 4.30's for the 8.8.

 

1-if you are talking about the 6 speed auto tundras, that is why, they have more gears in tranny. and 2-the tranny gearing probably isnt the same. just because you have a 3.55 and toyota has a 4.10 means nothing if the tranny gearing is different. ford's trannys could be higher in first gear than toyota or lower, that goes for all the gears. you gotta find out the drive ratio from each gear with the rear end being the way it is. that is the way to get the real gearing for each gear.

 

Im debating whether going 4.30 gears or 4.56 gears over stock 3.55:1. I think I may go Saleen rims one day for street so I'd like the 4.56 for the power being a 32.6" tire and the weight. But when I go to the track 4.56 gear with 28" tall drag radials may be to much!

 

well from experience(in a way) i had an 04 f150 heritage(97-03 style) reg cab longbed V6 2wd 5spd XL with 3.08 rear end and weighing 3897LBs. with that i got 18.9mpg average, then with a K&N replacement filter i got 19.9mpg average, and with a K&N 77 series cold air intake i got 22.5mpg average. 0-60 was 9.58 seconds(at the quickest i timed it, could have been better on times i didnt time it) and 2nd gear topped at about 65 mph at 5400rpms(which helps with 0-60 because it is only the shift from 1st to 2nd that it within that time) and 4th gear 100mph was 3600rpms. and 65mph in 5th gear was about 1800-1900rpms. i have a few videos on youtube of my heritage going 0-100 and also of my 08 f150 i have now. my 08 is a reg cab shortbed V6 5spd 2wd with a 3.55 rear end and weighing about 4364Lbs. with the 3.55 rear end i get about 19.9 with the same intake i had on the 04. and 0-60 was the same, but 2nd tops at about 55mph @5200rpms(limiter). so i have to shift twice before i hit 60 which adds to the time. so it would be quicker except i have to shift again. and for being almost 500Lbs heavier, it still hits 100mph about 5 seconds before my 04 did. also 100mph in 4th gear is 4000rpms and 5th gear @ 65 is about 2100or 2150rpms
also when you go from 3.08 to 3.55 your 1st gear launch will spin tired more easily.
my 08 is heavier and less aerodynamic than my 04 was so that is mostly why the MPGs went down. but if you were changing the gearing in your truck(not trading in like i did... long story)then you will be making it quicker unless you have to shift more like i do now.

 

Fords 4 Speed 4R75E
2.84 1.55 1.00 0.70

Toyotas 6 Speed
3.520 2.042 1.400 1.000 0.716

Tundras may be fast, but I've heard of endless tranny problems as well as many problems just in general with the trucks.

 

yup....its a toyota. just look at toyota's symbol...they circled the problem on their own

 

So did .... ford....?

 

Never mind...I see these are for rear application only....not 4x4

Hi,

Thanks for the link...is anyone using these in a 2004 - 2008 4X4?

Thoughts?

 

SHHHHHH...its a ford website.....gotta make fun of the others.... like dodge ram. how can you ram something when you are dodging it? lol
