What did I do wrong? I replaced my seals and installed new Progressive springs.......now, I have no give in forks! I used stock spacer, but, I didn't think it needed to be cut down, about 5/8" more above tube at install. added the 4 and 3/4" from top fork oil level, installed the caps, now, forks are hard.....does the 5/8ths of inch make that much difference?
 
Cut the tube just like the directions call for. Otherwise.....you get the problem that you have now......too much preload.

After that set the sag on the bike. Ive got progressive springs with a 1 inch drop in my 07. The front end always felt a little bit stiff, after i measured the sag, now I know why. I had a front end sag of about 15 mm, and it shouldve been atleast at 30 mm. After I took another 15 mm off of the PVC spacer........SO much better. After that the front sag was at 30 mm, and then changed back to the stock caps, so I'm about 35 mm right now.

Also look at this video, and see if there was anything left out.

5/8" isn't a whole lot of preload.

When you measured for the oil, was the spring removed from the tube and fork fully compressed?

If not, you have way too much oil and could be the problem.
 
I installed the stock length Progressive Springs and cut the PVC spacers provided by Progressive to 9.37" (9 - 3/8") and filled them to 4.8" down as shown in Sean's video and I am very happy that setup.

So I'd definitely cut the spacers down to the recommended length and then check the sag like Trauma did.

I got in touch with Progressive, and as always, I was in a hurry and looked at video instead of listening to what was being said..........I filled tubes with oil with springs out while extended instead of collapsed. Got it re-done, but, I still didn't cut stock tube cause I had 1 3/8" of tube above fork as opposed to only 1". Progressive said that would work well. If it's a bit too stiff for my comfort, I'll cut the nylon tubes down to 9 5/16" and remove stock tubes and install the nylon. Thanks, Steve Kent
