RPM Ski Doo / Lynx Titanium P Drive 850 Clutch Bolt & Conical Washer 417300522 & 250200144

Prevent clutch bolt fatigue, safeguard your crankshaft taper, and shave critical rotating mass with the RPM SXS Grade 5 Titanium pDrive Primary Clutch Bolt and Conical Washer Kit! Engineered specifically for high-output BRP Ski-Doo and Can-Am pDrive clutch systems, this high-tensile hardware package directly replaces failure-prone OEM factory bolts and stamped washers with precision-machined, aerospace-grade titanium.

Under intense launch loads, rapid back-shifting, and high-boost RPM cycles, standard factory steel clutch bolts can stretch, leading to loss of clamping force, clutch slippage, taper galling, or catastrophic clutch departure. Precision CNC-machined from certified Ti-6Al-4V (Grade 5 Titanium), this M14 x 144mm bolt and matched conical Belleville-style washer deliver extreme shear and tensile strength while dropping roughly 45% of the rotating mass off the crankshaft snout.

The included Grade 5 titanium conical washer is engineered with the exact concave spring geometry required to maintain consistent, uniform tension across thermal expansion cycles.

Key Highlights & Technical Specifications:

• Material: Certified Aerospace-Grade Ti-6Al-4V (Grade 5 Titanium)

• Bolt Sizing: M14 x 1.5 Pitch x 144mm Length

• Washer Specification: M14 Precision Conical Spring Washer (Matches OEM taper tension)

• OEM Cross-Reference: Direct replacement for BRP / OEM Part # 417300522 (Bolt) & 250200144 (Washer)

• Thread Locker: Medium-Strength Blue Loctite Required

• Weight Profile: ~45% lighter than standard factory steel hardware

• Corrosion Resistance: 100% impervious to rust, trail brine, belt dust, and corrosive cleaners

Installation & Torque Guidance:

⚠️ CAUTION: When replacing factory steel clutch hardware with titanium, always reduce the manufacturer's published torque specification by 10% to 15% to account for titanium's lower thread friction coefficient, and always apply medium-strength blue thread locker to threads prior to torquing.

Features:

• High-Strength Grade 5 Titanium: Unmatched tensile and yield strength prevents bolt stretch and fatigue under heavy launches, rough chop, and high-horsepower applications.

• Reduces Rotating Crankshaft Mass: Significantly lighter than OEM steel bolts, reducing inertia on the crankshaft snout for sharper throttle pickup and improved harmonics.

• Precision CNC-Rolled Threads: Rolled threads provide smooth torque application and exceptional fatigue resistance against vibrational shear.

• Matched Conical Spring Washer: Engineered conical profile maintains constant clamping load across high-temperature clutch cycles.

• Zero Rust or Galling: High-purity titanium will never corrode, seize, or pit from moisture, snow melt, or belt dust.

• 100% Direct Bolt-On Fitment: Direct drop-in geometry matches factory length, thread pitch, and clutch taper pockets.
