PRP Polaris RZR PRO XP4 / PRO R4 / Turbo R4 Composite Seat Mount Kit w/ Fixed Base (Pair)
The PRP Composite Seat Mount Kit with Fixed Base (4 Door) is engineered for riders who want maximum strength, stability, and precision fitment when installing PRP composite (hard shell) seats into their Polaris RZR PRO XP4, PRO R4, or Turbo R4.
Designed specifically for 4-seat models, this system features heavy-duty side mounts that allow you to dial in your seat height and angle for the perfect driving position. The included fixed base mounts attach directly to the factory Polaris seat sliders, giving you adjustability without sacrificing rigidity.
Unlike quick release setups, the fixed base design minimizes movement—making it the ideal choice for aggressive riding, racing, and high-performance builds where a solid seating position is critical.
