I live in Amarillo, Tx and there is a blacksmith here who only works on leaf springs. He re arced and heat treated all my springs and added a full lenth second leaf and used bolt style clips. With slightly longer shackles, I ended up with about 2 inch over stock lift and the shackles barely angled in the correct direction from verticle. I run 32X11.50 MTR and at full artic no rubbing, even at full turn. The whole deal about 750 out the door, and it rides great. I think it will hold its arch because he forged/heat treated each leaf. This is a lost art, he is one of few in the country who still hand makes leafs. Wheeled it with good results in New Mexico last week. Drive your truck down here from Oregon and I'll make you an appointment at Texas Spring.
