Front Springs
Ok i have a 88 250 im swapping a 60 into. im told that you get a few inches of lift from a D60. im wondering where that comes from. Did they use the same springs and shackle design from the 250's and 350's? Other than the spring rates are there any other diffrences?

ttb springs will fit, the only thing is that with the straight axle, theres more chance of the front diff bottoming out. at the least, you should throw in a add a leaf in the pack. that will bring you up a couple inches and give you the desired clearance

you want cheap and easy then go add a leaf. you just unbolt the u bolts and drop the axle about 8 inches. cut the stud on the leaf pack, throw the add a leaf in and get easily 3 inches. it calls for 2, but since your ttb is negative arch and the add a leaf is a couple inches positive arch you'll get what your after. you just slip the new leaf in, clamp it with a c clamp, slip the new centering pin bolt in and tighten the nut then jack the axle back up, throw the u bolts back on and your ready to rock and roll. shouldnt take more then an hour start to finish.

i looked at the add a leafs and thats an option. right now im looking for the heavier springs, i plan on hanging a plow on this truck sometime in the near future so i might as well do it now while its apart. however these must be the best trucks ever built in the history of the world because ive called every bone yard on the west side of ohio and there isnt a single one.

look at any newer psd and they are only 2 springs too. Add a lead adds height and adds weight capacity. Iv got a set of F350 springs here actually and iirc they are positive arch 2 spring, i'll check again when I get home though

f250 springs are actually not arched springs at all.they are flat.they negatively arch with the weight.
adding more springs,especially to the front,will drastically hurt your ride quality.
you may want to consider firestone rite rite air bags instead for your plow (but its more expensive.)
when you set your D60 up front,your going to want to set the rear end up,so the truck sets correctly again.
the easiest way is to use the f350's rear spring block in place of yours.

well im really not to worried about the ride, my 87 chevy 1 ton rides like a log wagon and it cant get much worse. i guess ill do the swap and see what happens. i might throw an add a leaf up front just for good measure, then leval out the rear.
