I was measuring from the ground to the bottom of the fender. It was noticably different even without a measurement. It's not body panel issues either because the passenger side also had negative camber. When I put the washers in the negative camber went away.

I've read on other forums that this is a very common problem when lowering. The best solution I could find after researching was to order new custom made springs. I didn't want that added expense so the washiers seem to work very well. Nothing more than a spacer to raise that side up alittle. With the washers it sits dead even and rides well too.

 

The fender is a body panel. If you measure any of our trucks they are almost never the same on each side.

If your springs are a matched pair, remove the washers and have it aligned. When you lower or lift a vehicle you it needs to be aligned at shop.

I don't mean to come off negative, but that is not the way to do it.

 

If my fender was off 5/8 of an inch my door or hood wouldn't come close to lining up. So you think it's more likely everyone that has experienced this has a fender that is misaligned vs maybe it's in the design of the ibeam? I find that very hard to believe that many people's fenders are misaligned.

I've read where others have put springs in from a regular f150 and still had this problem. The only solution I've found from reading is to order custom springs which would equate to the passengers side being just a bit larger than the drivers. Shimming my current spring achieves this at a fraction of the cost of new springs. As far as I can tell it has not negatively effected the ride quality.

Because my truck did not sag on the passenger side before I lowered it that leads me to feel my springs are fine. The only thing that changed is the ibeams so that makes me to believe the flaw is in the design of the ibeams. I am merely making up that 5/8's inch by shimming that side.
