ReArching Springs
My dads 78 F-250 4x4 sits way down in front (lower than my 2wd!). the springs are arched the wrong way. He wants to rearch them. He was thinking of taking them off and putting a come along between both ends and Arching them and let them sit for a few days. Think it will work? or will we just have to take them somewhere?

ReArching Springs
Rearching springs is a poor alternative, even when done by a shop. They soon lose their rearch due to the nature of the metal used in the leaves. Your method wouldn't work anyways. The best solution is to replace them.

When properly done rearching works well. I have had springs for two vehicles rearched and rebuilt and they have given excellent service. If the springs have broken leafs then the springs are probably shot. The shop I go to will rebuild them if only one leaf is broken out of the pair, but replacement is indicated if more leafs are broken.

None of them are broke, There is only 2 springs in the whole Spring pack, I thought there should be more. But the truck is a low boy. But i mean theres like 2" between the axle and frame.. So i will have to take them to a shop, how much will that cost?? Thanks James.

The heating process requires several steps. The springs are heated and then cooled slowly to anneal the metal. They are then heated again and cooled quickly to harden the metal. They are heated again to a very specific temperature and cooled to temper them.
If none of the leaves are broken the metal can be re-arched without heating with a very powerful press and a skilled operator. The metal is deformed just past the yield point and allowed to snap back correcting the curve on the springs. I have watched a very skilled operator do this and I was impressed by the accuracy of his work. My springs were re-arched without heating. The heat treatment process is more expensive. Springs are sometimes checked for cracks with magnaflux or dye penetrant equipment. A skilled operator can also spot a crack fairly easily.

I had my front springs re-arched about a month ago. They weren't heated up to be arched, the were put in a 50 ton press to be bent. they just kept moving the press to different spots and in about 3 minutes the springs were done. I couldn't be happier with teh results for the price.(all new back springs, re-arched fronts, all new hardware-$550) I was also told that if your worried about them "coming back down" they can put an add-a-leaf in to fix it.
