Lowering Shackle - Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought some 2" lowering shackles and expected the shackles to be 4" longer, they are 2.25" longer. How am I going to get a 2" drop if the shackle is only 2" longer. That would equal a 1" drop. Am I missing something?

The mounting holes on the shackles on the rig are 4" apart. Does anyone know if that is the measurement of an original shackle.

That sounds right. If you change nothing else, every 1 inch you add to the shackle the diff and frame come 1 inch closer together.
