Engineered specifically for the roller-bearing pDrive primary clutch on Ski-Doo 850 E-TEC mountain sleds, these weights feature an aggressive mountain cam profile that loads the engine hard on initial throttle crack while promoting instantaneous backshifting the second you let off in technical tree lines.\u003c\/p\u003e\n\n  \u003cp\u003eGoldstar weights eliminate the frustration of tiny set screws, stripped hex sockets, and messy thread-locking compounds. Our magnetic adjustment system utilizes high-strength neodymium magnetic slugs that snap securely into deep recessed pockets on each weight arm. Adjusting target shift RPM for changing elevations or snow conditions takes only minutes—simply pop magnets in or out right through the pDrive clutch openings without removing the clutch or weight pins.\u003c\/p\u003e\n\n  \u003cp\u003eTo withstand extreme mountain riding conditions, every Goldstar weight undergoes our proprietary \u003cb\u003e5-step metal treating process\u003c\/b\u003e. This specialized multi-stage heat treat and surface conversion creates a hard, low-friction exterior that prevents galling against pDrive rollers, resists moisture and salt corrosion, and eliminates the rapid surface wear common to bare-steel aftermarket weights.\u003c\/p\u003e\n\n  \u003chr\u003e\n\n  \u003ch3\u003eKey Performance Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eMountain-Optimized Cam Profile:\u003c\/b\u003e Delivers explosive off-idle track spin to jump on top of the snow, combined with razor-sharp backshift response when navigating tight trees and sidehills.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eTool-Free Magnetic Adjustment:\u003c\/b\u003e High-power magnetic slugs snap directly into recessed pockets—no loose set screws, Allen wrenches, or thread lock required.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eWide 44g–58g Tuning Window:\u003c\/b\u003e Allows micro-tuning in small gram increments to match specific elevations (from sea level to 12,000+ ft), track lengths, and engine modifications.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eProprietary 5-Step Surface Treatment:\u003c\/b\u003e Multi-stage heat treatment and protective surface conversion shields against rust, moisture, and premature roller wear.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eMaintains Factory Clicker Utility:\u003c\/b\u003e Works seamlessly alongside the OEM pDrive clicker adjustment system for rapid trailside RPM fine-tuning.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eEssential Kit Component:\u003c\/b\u003e This is the exact primary weight set included in our \u003cb\u003eSki-Doo 850 E-TEC Long Track High Elevation Stage 2 Clutch Kit\u003c\/b\u003e.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr\u003e\n\n  \u003ch3\u003eProduct Specifications \u0026amp; Contents\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eIncluded in Set:\u003c\/b\u003e (3) Goldstar Adjustable pDrive Clutch Weights, complete neodymium magnet tuning pack, and comprehensive setup chart.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eBase Weight (Empty):\u003c\/b\u003e 44.0 grams per arm.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eMaximum Loaded Weight:\u003c\/b\u003e 58.0 grams per arm.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eVehicle Fitment:\u003c\/b\u003e 2017+ Ski-Doo REV Gen4 and Gen5 850 E-TEC Summit, Freeride, and deep-lug Backcountry models equipped with the factory pDrive primary clutch.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Bikeman Performance","offers":[{"title":"Default Title","offer_id":53605510906149,"sku":"05-GSW-4458","price":229.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0749\/6436\/9701\/files\/05-GSW-4458.webp?v=1787582983","url":"https:\/\/www.bikemanperformance.com\/products\/goldstar-adjustable-clutch-weights-44-58g-ski-doo-850-e-tec-pdrive-mountain-05-gsw-4458","provider":"Bikeman Performance","version":"1.0","type":"link"}
