I have an 06 lariat with 26" rims. stock gears are 373 which puts me around the 300 area. 410's will put me back to where I need to be.

Can anyone tell me the best place to buy them?

 

also how do i find out if it's a 7.5 8 8.8 or a 9.5

 

Depends on what engine you have

3.73's to 4.10's is not worth the expense.

Is it 2wd or 4wd, and what engine? What is the tire (not wheel) size?

 

Everybody says that, but then they turn around and say 4.56 will ruin your highway gas mileage.

If money was no object, what would be the more efficient choice to turn a 35" tire with a 5.4?

Sorry for threadjacking.

 

yeah I spend most of my time driving so I don't want to lose the top end and fuel mileage. 410 is the ideal gear for me. i just need to figure out what rear end I have and where the best place to buy the gear.

5.4 3V v8 4 door lariat with stock 373 gear.

 

I have a SuperCrew FX4 5.4 with 3.73. I have a 9.75".

 

Ford doesn't have a 9.5" axle. Most 5.4's have a 9.75".

AGAIN - 2wd or 4wd?

 

2wd

 

With a 2wd, I'd get 4.30's.

 

I found out that my truck does have the 9.75 rear.
I'm putting it in the shop friday. 410 will bring my ratio a little over stock, so maybe the 430 will give me te take off I'm looking for, just don't want to lose to much top end and fuel mileage. I spend most of my time driving around the country

 

I found motive gear 4.30 ring and pinion on accu auto parts for $233.00.
is that a good brand gear and is that a good price??

 

just ordered motive gear 430 ring and pinion gear and master kit from accu auto parts. total price 534.00 with shipping.
thanks for the input
