PRP’s Composite Seat Mount for the Polaris RZR PRO XP, PRO R, and Turbo R lets you add your favorite hard shelled seat to your UTV. So you can get to riding in better comfort and containment in your RZR. These mounts work with any of PRP’s Composite Seats (and also many other composite seats). The side mounts attach to the sides of the seat, and have various mounting slots so that you can adjust the height and angle of the seat. The flat adapter brackets can be attached to one of the three base mounts that PRP offers for the RZR’s (either Quick Release, Fixed 2 Door, or Fixed 4 Door). All of those base mounts attach to the OEM Polaris Slider, so you can still slide the seat forwards and back to adjust for different drivers. Sold as a pair to fit both front seats. Fitment: Polaris RZR PRO XP, PRO XP4, PRO R, PRO R4, Turbo R, Turbo R4 (Front Seats only) Base Mounts Available: We give you the choice of which base mounts you want to pair up with the composite seat adapters. We recommend using the fixed brackets with the composite seats since it allows the least amount of movement and is the most secure. However for the PRO R (2 Door), the Quick Release Mounts are required because the seats need to be easily removeable to access the drive belt (located directly behind the seats and firewall).
