I have a '90 F-150 2wd. A friend of mine gave me the 4wd front springs off of his truck after he installed a 4" lift. Since my springs needed replacing anyway, he told me they would level out the front end of my truck. After I took the old springs out, I found that the 4wd springs were exactly the same as the ones already on my truck, but I went ahead and put the new ones in there anyway, since they were better than what I had. After all was said and done, it lifted the front end up about 1/2".

So my question is, if the spring are the same in both trucks, what makes the 4wd truck sit level in the front and the 2wd truck sit lower? Is it the fact that it has 2 shocks instead of only one? I wouldn't think so, since shocks do nothing for ride height. Then it would have to be the front axle, right? Anyway, I guess I need to buy a 2" leveling kit in my quest for a level-sitting truck.

Thanks for your help.

 

anyone?

 

I'm actually curious to hear about this one myself... what is it that the OEM parts of the 4WD has that the 2WD does not?

 

You can't compare the 90 to the 2000. The difference between a 4x4 and 4x2 on a 2000 is the whole front suspension. 4x4 uses torsion bars and 4x2 uses coil springs.
As to the 90, I would bet the difference is the spindle drop on the radius arms.

 

didn't even think about that. i'll have to investigate this further and take some measurements and i'll let everyone know.
