his front springs are custom made leaf packs. i questioned him already on it. lol thats my next step after shoving 63 inch chevy rear springs in.
what i was told
"The stock f350 front springs really suck flexing cause they are way too thick and are only 2 leafs. They are like3/4 inch thick each, if you go have a 5 or 6 leaf spring pack built, you might have more flex and a better ride.
They used 8 mm thick leaves on mine. I can go pretty fast in my truck without bottoming the suspension out. I even tore the front shockmount and shocks off with out noticing. I really need longer shocks or limit straps. "
