Hi alll.
i don't know if this is the right place to post this or not but...
I have a (see below) and it has broken rear springs on both sides. now i am thinking it is because of the 460's tourque. but am not sure. i bought tjhe truck that way. https://www.ford-trucks.com/user_gal...?userid=122117
my doner truck has a realy good spring pack. truck sits little higher on back and no broken springs. who ever had doner before realy babyd it.
now i do not want the same thing to happen again so i am asking for advice on what to do.
If you are using tall rear blocks to get your lift, that 460 will flex the rear springs *very* easily. If you can use the donor vehicle springs and keep the block height 4 inches or less, the springs should be OK.
I'd put the springs in and if see how the truck will sit with a set of 4 inch (or shorter) blocks. If you need more lift, you could install an add-a-leaf to each rear spring. That would give you another couple of inches.
I believe that your rear springs are 3 inches wide and just about any rear springs from an F-150 or F-250 through '96 would fit. Aftermarket springs are an option, but are fairly expensive.
With 4 inch blocks you should not need to install ladder bars. Even though your 460 produces lots of torque, your vehicle is not very heavy and the springs should not twist enough to break them.
I'd put in the replacement springs first and see how they work.
