Welcome to the site !!
I really don't recall ever seeing one , but also wondering why you would want one ?? , you realise that the swingarm moving up/down is going to wear right thru it on the back side of it right ?? , that is why they are made of plastic , they are considered a "wear part" like the chain slider
, they are just there to keep mud and rocks from directly hitting the shock shaft and denting it causing a seal leak issue , not to mention the fact that at times the chain can slap the side of it , with Carbon it will shred it .... if this is for bling on a bike that won't be ridden , then I am sure some anyone that makes carbon fiber parts could whip one up using the regular one as a template ...... But I will guarantee if you put one on a bike you actually ride , it will be toast within days or a few weeks at most ........
