      Struggling to get more cargo space from your RZR? Pick up the Polaris Bed Box Extender Kit and you’ll get a big bump in cargo space without restrictions or bulky add-ons.

      The Box Extender Kit gives you a quick and easy five inch extension to the top of your bed storage area. With that extra area you get more cargo capacity, extra support for your cargo, and several additional tie-down points. Perfect for adding an extra layer of gear like coolers, bags, or loose cargo. The extender is made from rugged plastic that weathers well and matches the look and texture of the stock RZR plastics so you retain that great factory look.

      Once you pick up your Polaris Bed Box Extender, just complete the quick installation and you’ll be ready to fill your UTV with plenty of gear for your next adventure.

    • Install this kit on a RANGER RZR to extend the vertical walls of the cargo box for increased cargo capacity, extra protection for cargo and additional tie-down points
    • Rugged, durable plastic matches the plastic of the stock cargo box for protection and an integrated look
    • Adds over 5" (12.7 cm) to the vertical walls of the cargo box
    • Increases the cargo capacity and the variety of cargo that can be carried securely
    • Offers additional tie-down points for securing cargo, and has grommets to accept bungee cord hooks
    • Installs easily
