Looking for someone who might be able to help me identify these forks I'm looking to buy. The seller is listing them as 2008, but I think they are from 07 as the top cap has the center "hex" nut (first picture). I was under the impression this changed in 2008 to the caps pictures in the second image.

If I'm correct, are there any performance differences between the two? Are the 08's "better" or improved in any way?
I can get the set 07 versions for $350 shipped, as I'm doing a SFF swap on my 17 KX450f.

Thanks for the help in advance!

The top ones I think are from the 2006 (I think) and are the same as the funky fork right before the Yamaha SSS forks. Get the ones without the hex in the middle.

I used a set from a 2010 KXF450 on my 2016 KXF450 and they were very good.

Is there a way to distinguish between 2006 and 2007? It seems they both have the hex in the middle of the top cap.

Double check yourself, but '06 was the 1st gen AOS, I believe '07 was 2nd gen like '06 YZ but with raised fork cap, '08 was same as '07 with raised fork cap but got DLC lowers and '09 was same as '08 but with recessed fork cap like the YZ.

06 had chrome bottoms. 07 first year for black bottoms. I think the 08s where similar to 07s but had Kashima Coated dampening rods or something like that. I remember them being very similar. 09 and up are the better forks. I would get those.

Thanks for all the help guys - Appreciate it!

I never know how accurate the parts fiche diagrams are. It shows in 08 they moved to the caps similar to the 09-12 bikes, hence my original concern. A bit hard to tell in the images shown but you can see the hex cap is gone in 08. Maybe certain 08's had them changed during the production?
