I am having my rig re-aligned after the 2 inch OME goes on.....Is this the correct thing to do? Or can I get by without it?

 

I think you should do definitely get the alignment done.

 

Definately align it but I would give it a couple days of easy driving to make sure everything is settled. It would suck if you had to have it realligned due to the suspension settling. All of that can be avoided by getting an alignment with a warranty on it.
