PRP’s Knee Pads for the Polaris RZR With Door Speakers are a must-have to get the most comfort out of your ride. A lot of newer model RZR's are coming speakers built into the upper doors (that can't fit our standard RZR door bag). So we created these knee pads to still give you the comfort that you need on long rides. The pads are just thick enough to stop your knees from hitting the doors. Both attach securely to the door by using J-clips, and a hook & loop strip. Comes with a Driver and Passenger side knee pad that provides that protection for both riders. FITMENT: 2014-2023 Polaris RZR S900, XP 1000, Turbo, Turbo S with Speakers in the Doors
