DESCRIPTION

Evolution Powersports is proud to introduce our XR Series direct replacement Primary Clutch Bolt for CFMOTO U10 Models! 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.

• Made in the USA from premium heat-treated alloy steel
  
• Tensile load tested at 38,570 lbs.
• Tensile stress tested at 167,696 psi
  
• Allows a higher hold-down torque on the clutch vs OEM
