If you didn't get it alligned right after putting the leveling kit on then yes....do it today. I've got the same leveling kit and I've been told by many credible sources that longer shocks aren't necessary unless you plan on off-roading and are flexing your suspension to full articulation. It's up to you, I've also heard that the stock shocks are crap and replacing them is always a good idea. I haven't done mine yet because I plan on putting a 3" lift on so I'll have to replace the shocks then. Good luck, hope this helps.
