Yes and no. Anytime you change vehicle ride height or get new tires you should get your alignment checked/adjusted. If you are going to be close to the same height then you can probably get away with not getting an alignment.This is probably a dumb question but I just ordered Bilstein 4600 shocks for front and rear. Once I get them in do I need an alignment?
Rear swaybar links won't make a difference to alignment either. Just install them whenever, especially since you got such a recent alignment.I think what I might do is hold off on the shocks for a month and do the rear swaybar links too, and then align it again after that
