I do not have them on my P500 (yet) but Ricochet seems to be a popular brand that people have talked about. There are other brands out there if you do a Google search too.
Welcome form Alabama.
I went with Ricochet A-Arm covers and their two piece rock sliders Honda Pioneer 500
but I ended up with a 3 piece 3/8" UHMW center skids from Universal Products that I found on ebay.
I think their are a few members who have fabricated their own covers, but I can't recall who they are.
