While I was working on getting my top end back together, I looked over and noticed the rear shock was a KYB shock. Checked the front and same thing. These are not remote reservoir shocks. I've only had this Rhino since August of last year and don't know the history. Prior owner said nothing had been done with the suspension. My question is, are these OEM shocks or are they upgraded shocks? I've read through a lot of the suspension thread but haven't found an answer. Thanks.
