I am selling an aftermarket solid billet aluminum primary clutch that fits all 2014-2019 Polaris RZRXP1000 XP4vehicles, both 2 and 4 door models. This clutch was cut out of a single piece of aluminum and holds up very well to the elements these clutches are exposed to!This clutch comes complete and ready for install! Included is all the weights, rollers, clutch spring, 2-way center bearing, etc, no assembly required.These units function very well! They have been through extensive testing in both desert and dune riding conditions and have performed smoother then the factory clutches that originally came on these cars. These clutches are built with the latest technology integrated into them and provide a nice crisp take off without any belt slip. The 2-way bearing is designed toprolong thebelt life of your vehicle. Each unit has been individually tested before shipment to ensure they are ready to install on your vehicle once they arrive. This isa must have for any RZR enthusiast as the clutch and belts are the usual failing culprit that will leave you stranded on a trip. These units are IN STOCK! They are READY TO SHIP!!
