As many times as RCD said it in the directions I would think it would matter. They act like its a big deal the way its in bold and repeated over and over again.

My coils don't sag and my bump stops are no where near bottoming out, but I have only had it on there for a couple months now.

 

i know thats what the directions said, i wanted to see if there was a difference there was none so i left it be. regaurd less even if you do install them upside down vs right side up its easy to swap them back and forth ....
