    In my on going qwest to finish my straight axle conversion, I had decided to swap in a 14FF in the rear. I have 7" of lift in the front through the brackets and a set of Deaver 4" lift springs. In the rear, I started with one of Watson's ORD shackle flip kits and a set of Pro-Comp 3" lift springs. Turns out that the springs are only for a pickup. I didn't figure out why the spring was so long and so soft until after I had swapped the spring hangers side for side, so that the distance from the front pivot to the rear was extended 2" further. But then we confirmed that the pickup springs are 65" long and the Sub's are 60". I am determined to use these springs so I cut the front brackets off the frame with the intention of moving them 3" forward to make room for the spring. Has anybody done this one already? How many leaves do you have to add to a 65"1/2 ton pickup to equal a standard 60" Sub spring? Second, if you have to move the front spring hanger, did you back it up with a plate on the inside of the frame rail? <font color="blue"> </font>

    What year sub are you working on? 60" leaf springs /forums/images/graemlins/dunno.gif

    Most of the suburbans have 52" or 56" rear leaf springs.
