I'm looking into different methods of dropping my truck. One is air bags. But if I decide to go with a stationary drop what parts would I use for a 350? I want to drop it 4 inches in the front and 6 in the back. I know I would have to use 3" leaf springs and 3" blocks in the back. But, the problem is, I heard that the torque of a 350 will snap the u-bolts on the blocks? Is this true? Any solutions?
