I would go with UHMW (plastic) either from Trail Armor or Factory UTV. Depending on what type of riding you do can dictate the thickness. I have the 1/2 skids a d 3/8 A-arms and couldn't be happier. Ive bashed quite a bit, and slid over quite a bit and they hold up well. They're not cheap, but neither was your machine. My factory one was ripped up in pretty short order, although it did do its job.
