do you mean kicking it straight back 3/4 of an inch......yes i have done mine...supposedly it aligns it better for a better angle...the thread i dunno...
When you lift your bumper.... you will feel that the top couple inches of suspension travel is not dampened by the shock very well in stock form. This is easy to check, it just feels dead and free moving.
After doing the mod, you will notice that the shock is dampening that top few inches of travel. This is noticeable on any rough terrain where the suspension drops out (rough trails, crossing trenches, etc) I have been very happy with the change.
