I am going from a PML to a 3" suspension lift. I have 2" rear shackles, but want to get the AAL kit. Do I need to get rid of the 2" shackles when I put the AAL kit and get 1" shackles? I am using the vehicle as an "Expedition" type vehicle so i require the AAL kit.

So, will or will not the 2"shackles work?

Thanks
