Ss forks may 'bolt-on' but they are wrong for an S. You can't slide them up, because they will hit the handlebars. Even trying to match the rear shock (and raise the bike) is a bad idea because the swingarm and shock mounts on an Ss/STT are different as well.
tleighbell is right, they are longer. Bummer, but I would suggest sending them back and getting the right set unless selling them is a better $$ for you.
If you are buying them used, I would
highly recommend servicing them no matter the claimed mileage. It will save you $$, time, and trouble
