To those in the know, Fox Racing Shox has Protune offerings that allows older suspension fork upgrades. I recently upgraded my 2010 Fox Racing Shox to 2011 with Kashima coating. It is a worthwhile upgrade that costs 1/3 less price vs new fork.
Protune can be done DIY or you can have your LBS upgrade your fork. Fox Racing Shox has detailed service instructions with pictures and video. You simply swap the new parts with the old parts. That's all there is to it! SEE BELOW.

Parts I used to Protune my Fox Racing Fork.

Remove all dampers and drain old oil

Replace dust wipers with new


Old vs New

Clean and inspect lower fork assembly

New dust wiper and foam rings installed. Ready for new stickers.

Old vs the new Kashima coating

Clean headset bearings while everything is taken apart

Inspect FIT and Air spring assemblies...looks good.

Put everything back together

Finished product. It is now Protuned 2010 F100 FIT with Kashima coating
Finally, clean up and open a nice bottle of Red wine. Enjoy!

That was a fun little project!
