From PS website, "Poison Spyder Rocker Knockers™ bolt to your Jeep's body in key areas, and interface with strenghtened areas of the underside of the tub such as body mounts, strenthening ribs, etc. Because they mount to the body itself, there is no resulting gap or misalignment when a body lift is installed."
Except they don't mount to the tub itself. The rubber buddy mount puck goes between the Rocker Knockers and the body.
