I have a Holz rear skid for the rev chassis w/ ice age rails that fit 8" wheels. The rails are powder coated black. This skid rocks, with dual rate springs and fox zero pros its offer a great ride and can handle whatever you throw at it. I bought an XP and it wont fit so I am bummed. It retails for $1600 but I will sell it for $900 with only 350 miles on it
