{"product_id":"rzrx300-primary","title":"RZRX300 Primary","description":"\u003cp\u003eThe KWI RZRX300 Primary Clutch System is a complete, ready-to-bolt-on primary clutch upgrade for the Polaris RZR XP — a brand-new OEM RZR primary clutch fully assembled in-house by KWI with the X300 Clutch Kit , RZRBlade 300 Billet Inner Sheave , and Billet Overdrive Cover pre-installed and ready to go. No send-in required, no assembly needed — pull your factory primary off, bolt this on, and ride. The X300 Clutch Kit delivers adjustable weight tuning, stronger backshifting, and more consistent power transfer for your exact setup and riding conditions. The RZRBlade 300 replaces the factory inner sheave — a known failure point — with aerospace-grade billet construction and Groovix Cooling Technology that actively manages belt temperatures under load. The Billet Overdrive Cover eliminates clutch flex, extends belt life, and unlocks 3–5 MPH of additional top-end speed by allowing the clutch to shift out further than the factory cover permits. Everything assembled, calibrated, and ready to deliver more power, better belt grip, smoother shifting, and cooler operating temperatures from the moment it goes on the machine.\u003c\/p\u003e","brand":"KWI Clutching","offers":[{"title":"Default Title","offer_id":67505965826338,"sku":"RZR-PRM-300","price":2400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0775\/2967\/8114\/files\/X300-Primaryfullsize.jpg?v=1791769093","url":"https:\/\/utahmotorworks.com\/products\/rzrx300-primary","provider":"Utah Motorworks","version":"1.0","type":"link"}
