To start with, during my research on this topic I came across this post on another board:

I ordered the 2" daystar spacers, however, wife is pissed that I might be 'ruining'the warranty. Any feedback would be appreciated.

Here is the Reply:

NO!!!! I work for ford here in Tucson, and the 2 in spacers will NOT void the warranty, Ford allows up to 3" of lift w/o messin up drive line angles up in the front drive section so assure her that you'll be fine.

This appears to answer the question as to warranty and what the front end parts will allow before being stressed.

I have also ordered 2 of these kits but there remains a question in my mind when comparing the sizes between these two spacers. The 2" kit is 1-5/8" tall and the 2.5" kit is 1-3/4" which obviously gives us a 1/8" difference. How can 1/8" make so much of a difference in ride height over the 2" kit? I am struggling with the physics over this one. I can understand causing a small shift in weight in a rear-ward direction and all depending on motor size and cab weight and size this may vary slightly but 1/8" to me does not appear like it will produce much of a difference.

I have read many posts where measurments before and after have been recorded on 2' and 2.5" kits both Daystar and Autospring and they all seem extremely close to each other but I keep reading posts on 2.5" kits being to high? With only an 1/8" difference I can't see where the 2 spacers could be all that different?

inserting a spacer is like raising the fulcrum of a lever.

Imagine a see-saw with the left hand kid sitting on the ground. If you raise the bar that the see-saw pivots on by an inch, the right hand kid who is up in the air will go higher by a good bit more than an inch.

this is how a tiny difference in spacer can give a large amount of lift difference

 

What is the point of a leveling kit, other than aesthetics?

 

It appears that 1 dealer tech offered his opinion on the subject. If there is a problem with the suspension or ride or shaking the dealer can blame that on the level kit, refuse any warranty repair and void your warranty.


Fitment of bigger tires, more ground clearance, so you don't slide out of the seats, to see over traffic easier...

 

I've been thinking about leveling my truck for along time now and it is finally done. I must say the ride has improved dramaticly. If I knew how much the ride would improve I would have ordered this kit when I bought the truck. Any of you guys with aftermarket wheels and rims will benefit greatly from the level kit. Ok, let me say that I had mine done by a professional truck shop who included the alignment. I'm quite certain that if I attempted this job myself my truck would be much worse off. The stearing wheel shake and minor vibration are gone! The truck brakes better due to the level stance and the over all ride is smoother and tighter than it has ever been. I don't know what to say other than I'm very happy with the outcome and the level /taller stance is definately worth the minor cost to have this mod done. If you are staying with stock wheels/tires I would not do the level kit.
Thanks to all you guys who gave advise in one of my threads, dservit,inbred, jimmy k, and others. pics to come soon.

How much did it cost, including labor?

 

Grumpsy, I paid $375.00. I know many have paid less, but this guy has a good rep and he's not a Truck Options type of store where you never know who is working /training on your vehicle.
After reading a few negative posts (inbred, notice I did not exagerate.) I was concerned about using the daystar product. However, I'm very happy with the result. Thanks to the guys.

Scott 7065, did you go with Daystar or Autospring?

 

after much consideration, I decided to go with the Daystar. uerathane over steel or aluminum spacers, while it may not last as long, just seemed to be the better option to me. I thought it had to smooth out the ride over the others, but I can't speak from experience. They are more labor intense which explanes why I paid more than some but it was worth it.

I would have to disagree with this. You are entitled to your opinion, so I am not flaming you. But....I feel that with the looks of this truck from the factory, that raked stance, the leveling kit makes any one of these trucks look better. I would suggest it for anyone. I still have the stock tires and rims on my FX4, and it looks just plain awesome the way it sits. Check my gallery for before and after pics. I get so many compliments from my friends around here on how nice it looks with just the leveling kit. I highly recommend the Autospring kit to anyone, as there is no spring compressing involved, and if you take care of your truck it will last the life of it. I have no experience with the Daystar spacers, so I can't really comment on those. Anyway, Leveling kits should be stock!

I also agree with inbreds fulcrum statement, hit the nail on the head with that one!

 

Great truck Robot!!!! Sent email. would love some details.

 

You have 18" wheels and bigger tires than some of the stock fords. The FX 4's look awesome regardless. I just think some of the fords with the smaller stock wheels and tires look as if they have been lifted but don't have their new tires on yet. I guess this is due to all the space in the fenders on the new Fords.

You have a nice truck
Scott

 

Sweet truck, Roboots21!
