I a 08' f150 xlt crew cab. I'm looking too put a 2.5 leveling kit from auto spring. I was told that truck will sit nose high with it. So i would need too put a bigger block in the rear. But i'm debating if i should go wtih the add leaf spring. Does anybody have any suggestions.

 

add a leaf is the way to go, more payload and its better than addin a block saw a episodes of trucks about it one time

 

i put a 2.5" on my 06 xlt s-crew, the front is half an inch higher now but its not obvious unless you stare at it for a while or measure it

 

I have a 2.5" on my wifes XLT and it looks level without actually measuring. Then its only like .25" higher in the front.

 

Typical add-a-leafs add about 2-2.5" of lift and most of the time make the ride a little stiffer. Just FYI...

 

add-a-leaf's do not add to to payload at all.

 

how do they not more leafs equals more payload is what i was taught, if im wrong please explain

 

you can't increase the payload more than what the factory rated it for. just because you would put F350 springs on a ford ranger, you still have the payload of a ford ranger. it will squat less, but you don't gain payload with it.

 

Read in the link. They claim it adds payload.

Regardless of your springs, you cannot go over the max payload the truck has, go for it, not my frame. it would be pretty sweet to be overloaded and brake a shackle hanger off. oh yeah and make sure you running P rated tires too

"Remember, overloading a vehicle with too much payload is a dangerous situation, one that can harm you, your passengers and other drivers. If a police officer pulls you over and determines that your vehicle is overloaded, it's possible that you may get a ticket for unsafely loading a vehicle -- something no one ever enjoys."
