{"product_id":"kwi-clutching-ultrashift-fusion-secondary-polaris-pro-r","title":"KWI Clutching UltraShift Fusion Secondary | Polaris Pro R","description":"\u003cp\u003eThe KWI Fusion Secondary is a patent-pending, full billet floating secondary clutch engineered from the ground up to bring Polaris RZR Pro R clutching to KWI standards — delivering true floating-secondary performance to the Pro R platform for the first time ever. Built around KWI's proven Floating Clutch Technology, it allows the secondary to self-align with the primary under load, eliminating the side-load, belt deflection, and friction that make the factory fixed secondary inefficient under real riding conditions.\u003c\/p\u003e\n\u003cp\u003eWhat's Included?\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eKWI Fusion Secondary\u003c\/li\u003e\n\u003cli\u003eKWI Kwik Lock Belt tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe floating hub design allows controlled lateral movement on the gearbox shaft, maintaining perfect belt alignment through the entire shift cycle. The result is cleaner belt-to-sheave contact, smoother RPM transitions, lower operating temperatures, reduced belt wear, and more wheel horsepower than any other clutch on the Pro R market — whether you're wide open in the dunes or crawling through the rocks.\u003c\/p\u003e\n\u003cp\u003ePaired with a Can-Am–style DR3 Groovix Helix, the Fusion Pro R Secondary delivers the same proven belt grip, aggressive backshifting, and active cooling performance found in KWI's championship-winning X3 setups. The DR3 Groovix is the most capable helix KWI builds — and now it's available for the Pro R platform.\u003c\/p\u003e\n\u003cp\u003eFor the first time on the Pro R, riders can fine-tune final drive ratio through belt selection — no gearbox changes required. Run a longer belt for higher top-end speed in the dunes and desert, or swap to a shorter belt for up to 15% gear reduction for rock crawling and technical terrain. Change your gearing in seconds, right at the clutch.\u003c\/p\u003e","brand":"KWI Clutching","offers":[{"title":"Default Title","offer_id":50613115060447,"sku":"KWI ProRFusionSecondary","price":2529.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1058\/1104\/files\/Screenshot2026-07-29152314.png?v=1785353413","url":"https:\/\/www.whalenspeed.com\/products\/kwi-clutching-ultrashift-fusion-secondary-polaris-pro-r","provider":"Whalen's Speed R\u0026D | Whalen Tuned","version":"1.0","type":"link"}
