Harness the full horsepower and brute low-end torque of your 850 E-TEC engine with Bikeman Performance Goldstar Adjustable Clutch Weights. In low-elevation environments (0–6,000 ft), dense atmospheric air produces maximum cylinder pressure and broad torque. Factory pDrive weights often lack the mass displacement required to clamp the drive belt properly under full sea-level power, resulting in belt slip, excessive heat cycles, and sluggish corner exit acceleration.

Goldstar 48–62g weights feature an aggressive low-elevation cam profile that loads the engine hard right out of the hole, transferring violent power directly to the track while locking your 850 E-TEC dead-center in its 7,900–8,000 RPM powerband. Say goodbye to tiny Allen set screws, stripped sockets, and messy thread-locking compounds. Our magnetic adjustment system utilizes high-energy neodymium magnetic slugs that snap securely into deep recessed pockets on each arm. Adjusting base mass takes only minutes—simply pop magnets in or out directly through the pDrive clutch openings without pulling ramps, pins, or removing the clutch from the crankshaft.

To endure thousands of miles of severe trail chatter and aggressive backcountry riding, every Goldstar weight undergoes our proprietary 5-step metal treating process. This multi-stage heat treatment and surface conversion produces an ultra-hard, low-friction exterior that prevents roller galling, resists rust and road-salt corrosion, and eliminates premature face wear common to bare-metal aftermarket weights.

Key Performance Features

• Low-Elevation Cam Profile: Calibrated to harness full sea-level engine torque, delivering explosive corner-to-corner acceleration, aggressive mid-range upshift, and sustained top-end pull.
• Tool-Free Magnetic Adjustment: High-power magnetic slugs snap securely into recessed weight channels—no loose screws, tiny wrenches, or thread lock required.
• 48g–62g Micro-Tuning Window: Allows fine gram adjustments to dial in target shift RPM across different track lengths, lug heights, studded setups, and engine modifications.
• Proprietary 5-Step Surface Treatment: Advanced heat treat and protective coating prevents rust, moisture degradation, and surface galling against pDrive rollers.
• Seamless Clicker Integration: Functions perfectly alongside factory Ski-Doo pDrive clickers for instantaneous trailside RPM trimming.
• Essential Kit Component: This is the exact primary weight set included in our Ski-Doo 850 E-TEC Low Elevation Stage 2 Clutch Kits (Long Track and Short Track configurations).
