X code front leaf springs

I'm looking for info on the X-code front leaf springs. I have an 03 that I want to put them on for a little more lift, but have now way of knowing what I already have. I realize it's on the doorjam stickers, but my truck is a recovered theft, and all the stickers are gone.

I'm wondering if there is a part number stamped on the spring somewhere, and if anyone knows what code each part number correlates to?

thanks
Eric

I have a F-350 dualie that sat down in the front about 2 inches from the factory. A friend of mine told me to order a set of F-450/550 leafs and it would improve ride and pickup the front end. Best $200 I spent. It picked up the front about 2 1/2 inches and made it ride much better.

The w's and X's are for the 450,550. You just need to get the x's as the w's won't raise it. I have the part number somewhere...

I recommend going to your local FORD Parts dept...and giving them your VIN. Let them find exactly how your SD was built and with what spring rates. Not a fun way to do it, but hope that helps.

You could always just buy a leveling kit...if you do not like the factory rake our SD's have.
