RPM Polaris Patriot Boost / 9r P22 Titanium Primary Clutch Bolt # 7528193 / 7520526 M14X1.5X180

Polaris Primary Clutch Bolt Screw 7528193 / 7520526

Eliminate clutch bolt stretch, prevent catastrophic clutch failure, and shed critical rotating mass with the RPM SXS Grade 5 Titanium Primary Clutch Bolt! Engineered specifically for high-demand, high-RPM Polaris platforms, this ultra-high-strength titanium bolt directly replaces weak factory OEM bolts (#7528193 and #7520526), providing maximum clamping security for your primary drive clutch.

Factory clutch bolts are prone to fatigue, stretching under violent clutch engagement, belt slap, and aggressive throttle snaps. A stretched or failed bolt can cause severe clutch taper slippage, crankshaft snout damage, or complete clutch assembly failure. Precision CNC-machined from aerospace-grade Ti-6Al-4V (Grade 5 Titanium), this primary bolt delivers exceptional tensile strength, zero corrosion, and superior fatigue resistance while drastically cutting down rotating mass off the crankshaft snout.

Designed to match exact factory thread and shank specifications (M14 x 1.5 x 180mm), this bolt torques smoothly to factory specification (65 ft-lb with medium-strength blue thread locker) and serves as an indispensable upgrade for high-boost, hard-launching Polaris engines.

Key Highlights & Technical Specifications:

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

• Dimensions: M14 x 1.5 Pitch x 180mm Length

• OEM Cross-Reference: Direct replacement for Polaris OEM Part # 7528193 & 7520526

• Torque Specification: 65 ft-lb (88 Nm) with Blue Loctite

• Weight Profile: ~45% lighter than standard steel bolts, reducing rotational mass on the crankshaft

• Corrosion Resistance: 100% Impervious to rust, moisture, and road salt

• Hardware Ecosystem: Matching RPM titanium secondary clutch bolts and tower cover hardware available separately

Features:

• Superior Tensile Strength: Extreme yield strength prevents bolt stretching and loosening under violent clutch shifts, high RPMs, and big-boost shock loads.

• Reduces Rotating Mass: Lightweight Grade 5 titanium lowers reciprocating mass directly at the crankshaft center, improving rev response and clutch harmonics.

• Precision CNC Rolled Threads: Rolled threads provide significantly greater fatigue life and smoother torque application compared to cut threads.

• Complete Corrosion Immunity: High-purity titanium will never rust, gall, or seize due to belt dust, snow melt, or trail wash chemicals.

• 100% Direct Bolt-On Replacement: Exact drop-in replacement matching factory length, shank diameter, and thread pitch.
