pDrive Adjustable Weight Pivot Bolt Kit (12–20.6g) for Ski-Doo 850 E-TEC // SKU: 05-202
⚙️ HARDWARE UPGRADE ADVISORY: This kit replaces the fragile factory 4mm Allen pivot bolts with heavy-duty, high-tensile 5mm Allen drive bolts. The larger hex socket prevents stripped fasteners during rapid trailside and mountain weight changes.
SKU: 05-202
Primary Clutch Compatibility: Ski-Doo pDrive Primary Drive Clutches
Adjustment Range: 12.0 grams (lighter than stock for extreme elevation) up to 20.6 grams
Primary Application: 2017+ Ski-Doo REV Gen4 & Gen5 850 E-TEC snowmobiles (Summit, Freeride, Renegade, MXZ, and Backcountry models).
Dial in your target shift RPM quickly and accurately with the Bikeman Performance pDrive Adjustable Weight Pivot Bolt Kit. The factory Ski-Doo pDrive primary clutch utilizes weighted pivot bolts inside the clutch arms to govern shift inertia and peak operating RPM. Our kit gives you complete control over this calibration, allowing you to fine-tune pivot weight in precise 1.2-gram increments without the expense of replacing entire arm assemblies.
Tuning between sea-level trail riding and high-elevation mountain backcountry has never been simpler. By swapping bolt lengths and stacking our precision 1.2-gram steel shims, you can adjust each arm anywhere from 12.0 grams up to 20.6 grams right through the clutch sheave openings—no need to pull the ramps, compress the spring, or remove the clutch from the engine.
Unlike factory BRP pivot bolts that rely on a tiny 4mm internal hex that is notorious for stripping out when locked with factory Loctite, Bikeman bolts are precision-machined from high-strength alloy steel with a deep 5mm hex socket for slip-free Allen key engagement every single time.
Key Performance Features
- Wide 12g to 20.6g Tuning Range: Adjust from 12.0 grams (substantially lighter than stock for thin mountain air above 8,000 ft) up to 20.6 grams for sea-level setups and modified engines.
- Micro-Gram Incremental Adjustments: Includes 15 precision-stamped 1.2-gram tuning shims to dial in exact target operating RPM (7,900–8,000 RPM sweet spot).
- No Ramp or Clutch Removal: Adjust pivot mass directly on the sled in minutes using standard hand tools.
- Upgraded 5mm Hex Fasteners: Heavy-duty bolt heads eliminate the stripped sockets, rounded heads, and seized hardware common to OEM 4mm factory bolts.
- Comprehensive Factory Weight Baseline Chart: Includes a detailed setup guide comparing all bolt and shim configurations directly against factory Ski-Doo baseline gram weights.
- Essential Kit Component: This is the exact adjustable pivot weight hardware included in our Ski-Doo 850 E-TEC Low Elevation Stage 2 Clutch Kits.
