    Nope. I installed the shackles and removed the lift block and my front is now 1/2" higher.

    Remember that when you raise one end of the leaf spring, the truck is lowered by half the amount the end of the spring was raised. I thought I had 2" shackles on my truck, but I measured them and they were 7" center-to-center. Stock shackles are around 4". So I raised the rear of the spring 3", effectively lowering the truck about 1.5". Just wanted to let you know that a lot of "2 inch" shackles only yield 1.5" of drop.
