Saggy Butt !!

I noticed my rear end was lower than the front by about an inch. After looking through the forum I decided to install longer leaf shackles. All went well and I installed them using the lowest hole, which should have given me 2 inches of lift, 1 inch to get it back level and 1 inch lift. To my surprise when I had finished and measured the car front and back are now level at 33inches. I went for a drive part of which included a bumpy road and it still measured all level and not the 1 inch of lift I had hoped for. My question is do you all think my leaf springs are on the way out? If so I think I may go with the F150 rebuild rather that re bend or new springs. Any advice would be most welcome.

when you go with longer shackles you also have to understand that when the shackle flexes from the weight it will also swing back more than the stock shackle. Generally a shackle that is 2 inches longer will give you about 1 1/4 inch of lift. As for the leaf packs, getting a heavier duty leaf pack will help more than re-arching the springs. The reason is after some time the springs will straighten out like they have done now. Plus at a you pull it junkyard you can get the f150 packs for the price of rearching.
