do it. they are fine. i ran 8" eye to eye shackles when i had dodge springs and they were fine.. and when i went to a totally custom pack i had 8" with drop shackles.. do it
Longer shackles arent a problem, if this is a DD/street driven, just be aware that it is going to increase sway in the rear. Not a huge deal, but take it easy in the corners until you get it felt out.
