Evolution Powersports is proud to introduce our XR Series direct replacement Primary Clutch Bolt for the Maverick X3! Our bolt is designed to yield more TQ to prevent the clutch from slipping on the crankshaft.
When the clutch slips, the rotation of the engine relative to the slipped clutch causes the bolt to tighten further. When this happens, due to the small minor diameter of the OEM bolt, it can shear off. As a result, the clutch comes off the crankshaft and wreaks havoc on the clutch, clutch housing, secondary clutch and crankshaft.
Don't risk severe clutch / crankshaft damage with a weak primary clutch bolt!
Features:
- Made in the USA from premium heat-treated alloy steel
- Larger outer diameter than OEM bolt where it passes through the puller threads before engaging the crankshaft, which equates to greater torque holding capacity
- Tensile load tested at 38,570 lbs.
- Tensile stress tested at 167,696 psi
- Additional thread engagement on the crankshaft to prevent stripped threads
- Allows a higher hold-down torque on the clutch vs OEM
- Reuses OEM washer
