These side case guards are machined from billet aluminum and anodized black.  Very nice, high quality pieces. We are selling these at a reduced price due to an issue we found.  If you are running one of our engine skid plates, the left case guard will make contact with inner left side of the skid plate.  This may require slotting the front skid mounting holes slightly to shift the skid plate to the left to allow clearance for the left side case guard.  Pic of the slotting included.
