What is the purpose of a secondary clutch spring?

The secondary clutch spring works with your ATV's clutch to control how and when power is transferred to the wheels. A new spring helps ensure smooth engagement and proper performance.

How do I know if my clutch spring needs replacing?

Signs of a worn clutch spring can include inconsistent acceleration, sluggish performance, or a clutch that doesn't engage smoothly. If you're experiencing these issues, replacing the spring is a good step.

What does the 5% tolerance mean for this spring?

The 5% tolerance means that each spring manufactured will be very close to the specified load ratings. This consistency ensures reliable and predictable clutch performance every time.
