just put the set on. piece o' cake.
these are definitely a little stiffer than the factory units on my 2002 SE 2WD. not objectionably stiff, and maybe they will break in or maybe I will get used to them, but something to keep in mind. if you are concerned about shocks being too stiff, the bilstiens might not be the ones for you.
BTW I got about 50K out of the factory units before they started to go bad. by 60K they were bad.
just put on some kumho tires too, they are nice.
