Offset spring kits???

I guess I just don't see how they get 3/4" with their 'kit.' There's only a 1/2" between the stock front hanger location and the frame rail. Do the shackles have 3/4" offset? Even if they did, it wouldn't translate to 3/4" at the spring perch.

I just finished one side on my 1/2" move yesterday. I notched the frame for the front hanger bolt and just redrilled the holes to make the hanger flush with frame. Then drilled new holes in the rear hanger to utilize the stock holes.

Sure beats the $220 the Mopar kits sell for. I can't believe no one else does this.
