Mooso...........Whoa bubba...!
Here is a link to Alden's site, with a basic pic of their double adjustable. If you look, there are 'centering' rims on there. Also you will see the normal/correct position of the shock itself. (btw, a bunch of us got some from them last year).

I will admit though, the springs (even theirs direct) don't exactly center as much as I'd like to see, but they wont move. So basically you should have the top and bottom centering the springs just fine.
