Yes, plastic! This is a product from our friends at Acerbis. Ultra tough injection molded reinforced composite. Flexible Heavy-Duty Polypropylene will not effect chassis ability to flex, will not effect handling

It's twice as thick as a metal skid plate but is only half the weight. Plastic glides over rocks and roots better than aluminum. It also reflects less engine noise. Full coverage, mounts to existing threaded holes at the rear of the frame.
