Conversation Between tjc transport and mason97x

i don't think what you are proposing will work. the reason the 4 in front and 6 in the back worked for me is because that truck was also converted from IFS to solid axle which was an extra 2 inches in the front to make it sit level. what you propose to do will most likely make the truck sit higher in the front than the rear by around 2 inches.
i would suggest run your plan by the guys that hang out in the suspension forum, they will be able to get you on target with the proper parts.

Hello,
My name is Mason and I have a 2000 7.3 F350 ccsb srw and I am planning on installing pro comp 22410 4" front leafs and in the rear I wanted to remove the 3.75" block and install pro comp 22415 rear 5" leafs and was wondering if this would work. I saw on an old post where you had installed 4" front springs and 6" rear springs. Would there be any way to make the factory overload work?
