i have a 2000 F250 and im thinking about getting a lift im just not sure what size to go. if i go with the 8 in will i have to get alot of other things adjusted like gears and steering ect.... as opposed to going with a 6 in?

 

ur tires u move up to will determine it mostly...

but YES, expect to have to buy more stuff then just the lift kit when u go that high...

the good quality lift kits will have everything u need from a suspension standpoint but it wouldnt in any way address the braking and regearing needed for much larger tires...

 

It's a guy thing to think bigger is always better, but reality is that you'd likely be happier with the 6" lift. Or less...

 

i really dont want to get into regearing, steering issues and all that other stuff if i can avoid it. so with a 6 in lift i can get around all that, say with 35-37 inch tire??

 

a diesel will cope with 35"s tires better then a gasser without regearing...

but even at 35"s tires ur gunna notice a difference...

steering related parts will all be provided with a good quality kit...again the more u spend the better the kit ur gunna get (within reason of course)...

only u will be able to tell if the larger tires are livable after alls said n done...but dont be surrpized within a month or 2 of getting the lift and big tires ur looking at ways to get more power back ..8-)

 

Out of curiosity, why are you lifting it? Do you tow with your truck? Load much in to and then out of the bed?

 

What engine, trans, and axle gears do you currently have in the truck?

 

I have the V10 with 4.30 gears i beleive , auto trans with 4X4

 

Furian's got a good point. Do you use your truck to work or tow... or is it recreational? One of my new neighbors has a V10 with what looks like at least 35's from a distance, could be bigger. If I see them out I'll ask them if they think.

 

I mostly recreational use, but i do tow a from time to time. id apprecieate you asking your nieghbor, that would be cool.

 

to fit 35's a four inch is all you need on our trucks, i've seen alot of trucks with this setup and they look awesome, when i get the money to regear again ill be buying a four inch lift with 35's also. with your V10 power shouldnt be bad especially compared to my 5.4 but guys on here with your motor usually only go to 4.56 if they tow but if you dont tow heavy or alot your 4.30 will do fine with the power of the V10

 

Mine's an 06 V10 4:10 gears. I know it's the 3V engine and different suspension but I was getting 11mpg stock and now 9mpg, changing from stock 33's to 37's. With the SCT X3 from 5star I can still put down I nice patch of rubber. With 4:30's I think you should be good up to around 37-38's. Now you will loose power but I figure if I can still spin my tires (not powerbraking) then I still have enough. I would consider 4:88's in mine when the money is available. But it runs great so I'm not sure.

 

Have a 4" on my 08' with 35's and 4:10's. Love the setup. do alot of towing and off-roading and it does quite well. Get 9.5 mpg while towing and right at 12 regular driving.

 

Papadelogan get's credit for asking that question...

 

Assuming that you have 4.30 gears and driving at 65 MPH, here is what is going to happen to the RPM's with various tire sizes using a .71 transmission high gear ratio:

31" Tires - 2,152 RPM's
33' Tires - 2,022 RPM's
35" Tires - 1,906 RPM's
37" Tires - 1,803 RPM's

That's a 3K drop in RPM's going from 31" tires to 37" tires. To keep your current RPM's, you will need to install 5.13 gears. You can use the RPM Calculator to confirm these numbers.
